The hands'" (med. /lat.: manus, pl. manūs) are the two intricate, prehensile, multi-fingered body parts normally located at the end of each arm of a human or other primate. They are the chief organs for physically manipulating the environment, using anywhere from the roughest motor skills (wielding a club) to the finest (threading a needle), and since the fingertips contain some of the densest areas of nerve endings on the human body, they are also the richest source of tactile feedback so that sense of touch is intimately associated with human hands. Like other paired organs (eyes, ears, legs), each hand is dominantly controlled by the opposing brain hemisphere, and thus handedness, or preferred hand choice for single-handed activities such as writing with a pen, reflects a significant individual trait. What constitutes a hand? Many mammals and other animals have grasping appendages similar in form to a hand such as paws, claws, and talons, but these are not scientifically considered to be hands. The scientific use of the term "hand" to distinguish the terminations of the front paws from the hind ones is an example of anthropomorphism. The only true hands appear in the mammalian order of primates. Hands must also have opposable thumbs, as described later in the text. Humans have only two hands (except in cases of polymelia), which are attached to the arms. Apes and monkeys are sometimes described as having four hands, because the toes are long and the hallux is opposable and looks more like a thumb, thus enabling the feet to be used as hands. Also, some apes have toes that are longer than human fingers. Anatomy of the human hand. The human hand consists of a broad palm (metacarpus) with 5 digits, attached to the forearm by a joint called the wrist (carpus). The back of the hand is formally called the dorsum of the hand. Digits. The four fingers on the hand are used for the outermost performance; these four digits can be folded over the palm which allows the grasping of objects. Each finger, starting with the one closest to the thumb, has a colloquial name to distinguish it from the others: The thumb (connected to the trapezium) is located on one of the sides, parallel to the arm. The thumb can be easily rotated 90°, on a level perpendicular to the palm, unlike the other fingers which can only be rotated approximately 45°. A reliable way of identifying true hands is from the presence of opposable thumbs. Opposable thumbs are identified by the ability to be brought opposite to the fingers, a muscle action known as opposition. Bones. The human hand has 27 bones: the carpus or wrist account for 8; the metacarpus or palm contains 5; the remaining 14 are digital bones; fingers and thumb. The eight bones of the wrist are arranged in two rows of four. These bones fit into a shallow socket formed by the bones of the forearm. The bones of proximal row are (from lateral to medial): scaphoid, lunate, triquetral and pisiform. The bones of the distal row are (from lateral to medial): trapezium, trapezoid, capitate and hamate. The palm has 5 bones (metacarpals), one to each of the 5 digits. These metacarpals have a head and a shaft. Human hands contain 14 digital bones, also called phalanges, or phalanx bones: 2 in the thumb (the thumb has no middle phalanx) and 3 in each of the four fingers. These are: Sesamoid bones are small ossified nodes embedded in the tendons to provide extra leverage and reduce pressure on the underlying tissue. Many exist around the palm at the bases of the digits; the exact number varies between different people. Articulations=== Also of note is that the articulation of the human hand is more complex and delicate than that of comparable organs in any other animals. Without this extra articulation, we would not be able to operate a wide variety of tools and devices. The hand can also form a fist, for example in combat, or as a gesture. Muscles and tendons. The movements of the human hand are accomplished by two sets of each of these tissues. They can be subdivided into two groups: the extrinsic and intrinsic muscle groups. The extrinsic muscle groups are the long flexors and extensors. They are called extrinsic because the muscle belly is located on the forearm. The intrinsic muscle groups are the thenar and hypothenar muscles (thenar referring to the thumb, hypothenar to the small finger), the interosseus muscles (between the metacarpal bones, four dorsally and three volarly) and the lumbrical muscles. These muscles arise from the deep flexor (and are special because they have no bony origin) and insert on the dorsal extensor hood mechanism. The fingers have two long flexors, located on the underside of the forearm. They insert by tendons to the phalanges of the fingers. The deep flexor attaches to the distal phalanx, and the superficial flexor attaches to the middle phalanx. The flexors allow for the actual bending of the fingers. The thumb has one long flexor and a short flexor in the thenar muscle group. The human thumb also has other muscles in the thenar group (opponens- and abductor muscle), moving the thumb in opposition, making grasping possible. The extensors are located on the back of the forearm and are connected in a more complex way than the flexors to the dorsum of the fingers. The tendons unite with the interosseous and lumbrical muscles to form the extensorhood mechanism. The primary function of the extensors is to straighten out the digits. The thumb has two extensors in the forearm; the tendons of these form the anatomical snuff box. Also, the index finger and the little finger have an extra extensor, used for instance for pointing. The extensors are situated within 6 separate compartments. The 1st compartment contains abductor pollicis longus and extensor pollicis brevis. The 2nd compartment contains extensors carpi radialis longus and brevis. The 3rd compartment contains extensor pollicis longus. The extensor digitorum indicis and extensor digititorum communis are within the 4th compartment. Extensor digiti minimi is in the fifth, and extensor carpi ulnaris is in the 6th. Variation. Some people have more than the usual number of fingers or toes, a condition called polydactyly. Others may have more than the typical number of metacarpal bones, a condition often caused by genetic disorders like Catel-Manzke syndrome. The average length of an adult male hand is 189 mm, while the average length of an adult female hand is 172 mm. The average hand breadth for adult males and females is 84 and 74 mm respectively. A bell'" is a simple sound-making device. The bell is a percussion instrument and an idiophone. Its form is usually an open-ended hollow drum which resonates upon being struck. The striking implement can be a tongue suspended within the bell, known as a "clapper", a small, free sphere enclosed within the body of the bell, or a separate mallet. Bells are usually made of cast metal, but small bells can also be made from ceramic or glass. Bells can be of all sizes: from tiny dress accessories to church bells weighing many tons. Church and temple bells. In the Western world, its most classical form is a church bell or town bell, which is hung within a tower and sounded by having the entire bell swung by ropes, whereupon an internal hinged clapper strikes the body of the bell (called a free-swinging bell). A set of bells, hung in a circle for change ringing, is known as a ring of bells. In the Eastern world, the traditional forms of bells are temple and palace bells, small ones being rung by a sharp rap with a stick, and very large ones rung by a blow from the outside by a large swinging beam. The striking technique is employed worldwide for some of the largest tower-borne bells, because swinging the bells themselves could damage their towers. In the Roman Catholic Church and among some High Lutherans and Anglicans, small hand-held bells, called Sanctus or sacring bells, are often rung by a server at Mass when the priest holds high up first the host, and then the chalice immediately after he has said the words of consecration over them (the moment known as the Elevation). This serves to indicate to the congregation that the bread and wine have just been transformed into the body and blood of Christ (see transubstantiation), or, in the alternative Reformation teaching, that Christ is now bodily present in the elements, and that what the priest is holding up for them to look at is Christ himself (see consubstantiation). Japanese religious bells. Japanese Shintoist and Buddhist bells are used in religious ceremonies. "Suzu", a homophone meaning both "cool and refreshing," are spherical bells which contain metal pellets that produce sound from the inside. The hemispherical bell is the "Kane" bell, which is struck on the outside. See also Kane (musical instrument). Buddhist bells. Buddhist bells are used in religious ceremonies. Bell construed as a cause for war. On January 15, 1602 ("Keichō 7"), a fire broke out at Hōkō-ji, Buddhist temple complex in Kyoto. The great image of the Buddha and the structure housing the statue, the "Daibutsu-den", were both consumed by the flames. In 1610, Toyotomi Hideyori decided to sponsor rebuilding the Hōkō-ji and he also decided to order a great bell cast in bronze. On August 24, 1614 ("Keichō 19"), the huge new bronze bell was cast successfully. Dedication ceremonies were scheduled, but at the last minute, Tokugawa Ieyasu forbade the ceremonies to take place because he construed inscriptions on the bell to have been a personal affront: This contrived dispute led to the, which was a series of battles between armies of the Tokugawa shogunate and the samurai of the Toyotomi clan. The siege lasted through 1615. It is conventionally divided into two stages: the Winter Campaign and the Summer Campaign. In the end, the total destruction of the Toyotomi eliminated the last major opposition to the shogunate which would come to dominate Japan for the next 250 years. Bellmaking. The process of casting bells is called bellmaking or bellfounding, and in Europe dates to the 4th or 5th century. The traditional metal for these bells is a bronze of about 23% tin. Known as "bell metal", this alloy is also the traditional alloy for the finest Turkish and Chinese cymbals. Other materials sometimes used for large bells include brass and iron. Bells are always cast mouth down. Bells are made to exact formulas, so that given the diameter it is possible to calculate every dimension, and its musical note, or tone. The frequency of a bell's note in Hz varies with the square of its thickness, and inversely with its diameter. Much experimentation has been devoted to determining the exact shape that will give the best tone. The thickness of a church bell at its thickest part, called the 'sound bow' is usually one thirteenth its diameter. If the bell is mounted as cast, it is called a "maiden bell" while "tuned bells" are worked after casting to produce a precise note. Bell towers. Bells are also associated with clocks, indicating the hour by ringing. Indeed, the word "clock" comes from the Latin word "cloca", meaning bell. Clock towers or bell towers can be heard over long distances which was especially important in the time when clocks were too expensive for widespread use. In the case of clock towers and grandfather clocks, a particular sequence of tones may be played to represent the hour. One common pattern is called the "Westminster Quarters," a sixteen-note pattern named after the Palace of Westminster which popularized it as the measure used by "Big Ben". Bells as musical instruments. Some bells are used as musical instruments, such as carillons, (clock) chimes, or ensembles of bell-players, called bell choirs, using hand-held bells of varying tones. A "ring of bells" is a set of 4 to twelve bells or more used in change ringing, a particular method of ringing bells in patterns. A peal in changing ringing may have bells playing for several hours, playing 5,000 or more patterns without a break or repetition.. Ancient Chinese bells. The ancient Chinese bronze chime bells called bianzhong or (鐘) are among the highest achievements of Chinese bronze casting technology. These chime bells were used as polyphonic musical instruments and some of these bells have been dated at between 2000 to 3600 years old. The secret of the design and the method of casting zhong bells, which was known only to the Chinese in antiquity, was lost in later generations. It was not fully rediscovered and understood until 1978, when a complete ceremonial set of 65 "zhong" bells was found in a near-perfect state of preservation during the excavation of the of Marquis Yi, who died ca. 430BCE. Yi was ruler of Zeng, one of the Warring States which at the time of his death was under control of the Chǔ state. This region is now part of the present-day Hubei province. Although tuned bells have been created and used for musical performance in many cultures, zhong are unique among all other types of cast bells in several respects. They have a lens-shaped (rather than circular) section and the bell mouth has a distinctive "cutaway" profile, and this special shape gives zhong bells the remarkable ability to produce, depending on where they are struck. The interval between these notes on each bell is either a major or minor third, equivalent to a distance of four or five notes on a piano.. The bells of Marquis Yi, which are still fully playable after almost 2500 years, cover a range of slightly less than five octaves but thanks to their twin-tone capability, the set can sound a complete 12-tone scale, predating the development of the European 12-tone system by some 2000 years, and can play melodies in diatonic and pentatonic scales These bells usually have inscriptions on them from which scholars used as references for studying ancient Chinese writings (also known as Bronzeware script). Another related ancient Chinese musical instrument is called qing (pinyin qing4) but it was made of stone instead of metal. Konguro'o. Konguro'o is a small bell, which as well as Djalaajyn firstly had the utilitarian purposes and only after artistic ones. Konguro'o sounded by the time of moving to the new places, being fastened to the horse harness it created very specific "smart" sound background. Konguro'o also hanged on the neck of leader goat, which leads the flock of sheep in some definite direction. That is why in folk memory almost magic sound of konguro'o was associated with nomadic mode of life. To make this instrument Kyrgyz foremen used cooper, bronze, iron and brass. They also decorated it with artistic carving and covered with silver. Sizes of the instruments might vary in considerable limits, what depended on its function. Every bell had its own timbre. Chimes. A variant on the bell is the tubular bell. Several of these metal tubes which are struck manually with hammers, form an instrument named "tubular bells" or "chimes". In the case of wind or aeolian chimes, the tubes are blown against one another by the wind. Farm bells. Whereas the church and temple bells called to mass or religious service, bells were used on farms for more secular signaling. The greater farms in Scandinavia usually had a small bell-tower resting on the top of the barn. The bell was used to call the workers from the field at the end of the day's work. In folk tradition, it is recorded that each church and possibly several farms had their specific rhymes connected to the sound of the specific bells. An example is the Pete Seeger song "The Bells of Rhymney".
