In anatomy, an arm'" is one of the upper limbs of an animal. The term "arm" can also be used for analogous structures, such as one of the paired upper limbs of a four-legged animal, or the arms of cephalopods. In the lexicon of human anatomy, the term "arm" refers specifically to the segment between the shoulder and the elbow. The segment between the elbow and wrist is the forearm. However, in colloquial speech the term "arm" often refers to the entire upper limb from shoulder to wrist. In primates the arms are richly adapted for both climbing and for more skilled, manipulative tasks. The ball and socket shoulder joint allows for movement of the arms in a wide circular plane, while the presence of two forearm bones which can rotate around each other allows for additional range of motion at this level. Anatomy of the human arm. The human arm contains 30 bones, joints, muscles, nerves, and blood vessels. Many of these muscles are used for everyday tasks. Bony structure and joints. The humerus is the (upper) arm bone. It joins with the scapula above at the shoulder joint (or glenohumeral joint) and with the ulna and radius below at the elbow joint. Elbow joint. The elbow joint is the hinge joint between the distal end of the humerus and the proximal ends of the radius and ulna. The humerus cannot be broken easily. Its strength allows it to handle loading up to 300lbs. Osteofascial compartments. The arm is divided by a fascial layer (known as lateral and medial intermuscular septa) separating the muscles into two "osteofascial compartments": The fascia merges with the periosteum (outer bone layer) of the humerus. The compartments contain muscles which are innervated by the same nerve and perform the same action. Two other muscles are considered to be partially in the arm: Cubital fossa. The cubital fossa is clinically important for venepuncture and for blood pressure measurement. It is an imaginary triangle with borders being: The structures which pass through the cubital fossa are vital. The order from which they pass into the forearm are as follows, from medial to lateral: Nerve supply. The musculocutaneous nerve, from C5, C6, C7, is the main supplier of muscles of the anterior compartment. It originates from the lateral cord of the brachial plexus of nerves. It pierces the coracobrachialis muscle and gives off branches to the muscle, as well as to brachialis and biceps brachii. It terminates as the anterior cutaneous nerve of the forearm. The radial nerve, which is from the fifth cervical spinal nerve to the first thoracic spinal nerve, originates as the continuation of the posterior cord of the brachial plexus. This nerve enters the lower triangular space (an imaginary space bounded by, amongst others, the shaft of the humerus and the triceps brachii) of the arm and lies deep to the triceps brachii. Here it travels with a deep artery of the arm (the profunda brachii), which sits in the radial groove of the humerus. This fact is very important clinically as a fracture of the bone at the shaft of the bone here can cause lesions or even transections in the nerve. Other nerves passing through give no supply to the arm. These include: Arteries. The main artery in the arm is the brachial artery. This artery is a continuation of the axillary artery. The point at which the axillary becomes the brachial is distal to the lower border of teres major. The brachial artery gives off an important branch, the profunda brachii (deep artery of the arm). This branching occurs just below the lower border of teres major. The brachial artery continues to the cubital fossa in the anterior compartment of the arm. It travels in a plane between the biceps and triceps muscles, the same as the median nerve and basilic vein. It is accompanied by venae comitantes (accompanying veins). It gives branches to the muscles of the anterior compartment. The artery is in between the median nerve and the tendon of the biceps muscle in the cubital fossa. It then continues into the forearm. The profunda brachii travels through the lower triangular space with the radial nerve. From here onwards it has an intimate relationship with the radial nerve. They are both found deep to the triceps muscle and are located on the spiral groove of the humerus. Therefore fracture of the bone may not only lead to lesion of the radial nerve, but also haematoma of the internal structures of the arm. The artery then continues on to anastamose with the recurrent radial branch of the brachial artery, providing a diffuse blood supply for the elbow joint. Veins. The veins of the arm carry blood from the extremities of the limb, as well as drain | A bottle'" is a container with a neck that is narrower than the body and a "mouth." Bottles are often made of glass, clay, plastic or other impervious materials, and typically used to store liquids such as water, milk, soft drinks, beer, wine, cooking oil, medicine, shampoo, ink and chemicals. A device applied in the bottling line to seal the mouth of a bottle is termed a bottle cap (external), or stopper (internal). A bottle can also be sealed using induction sealing. The bottle has developed over millennia of use, with some of the earliest examples appearing in China, Phoenicia, Rome and Crete. The Chinese used bottles to store liquids. In modern times for some bottles a legally mandated deposit is paid, which is refunded after returning the bottle to the retailer. For other glass bottles there is often separate garbage collection for recycling. History. Since prehistoric times, bottle containers were created from clay or asphaltum sealed woven containers. Early glass bottles were produced by the Phoenicians; specimens of Phoenician translucent and transparent glass bottles have been found in Cyprus and Rhodes generally varying in length from three to six inches. These Phoenician examples from the first millennium BC were thought to have been used for perfume. The Romans For wine. The glass bottle was an important development in the history of wine, because, when combined with a high-quality stopper such as a cork, it allowed long-term aging of wine. Glass has all the qualities required for long-term storage. It eventually gave rise to "château bottling", the practice where an estate's wine is put in bottle at the source, rather than by a merchant. Prior to this, wine would be sold by the barrel (and before that, the amphora) and put into bottles only at the merchant's shop, if at all. This left a large and often abused opportunity for fraud and adulteration, as the consumer had to trust the merchant as to the contents. It is thought that most wine consumed outside of wine-producing regions had been tampered with in some way. Also, not all merchants were careful to avoid oxidation or contamination while bottling, leading to large bottle variation. Particularly in the case of port, certain conscientious merchants' bottling of old ports fetch higher prices even today. To avoid these problems, most fine wine is bottled at the place of production (including all port, since 1974). There are many sizes and shapes of bottles used for wine. Some of the known shapes: Codd-neck bottles==. In 1872, British soft drink maker Hiram Codd of Camberwell, south east London, designed and patented a bottle designed specifically for carbonated drinks. The "'Codd-neck bottle'", as it was called, was designed and manufactured to enclose a marble and a rubber gasket in the neck. The bottles were filled upside down, and pressure of the gas in the bottle forced the marble against the washer, sealing in the carbonation. The bottle was pinched into a special shape, as can be seen in the photo to the right, to provide a chamber into which the marble was pushed to open the bottle. This prevented the marble from blocking the neck as the drink was poured Soon after its introduction, the bottle became extremely popular with the soft drink and brewing industries mainly in Europe, Asia and Australasia, though some alcohol drinkers disdained the use of the bottle. One etymology of the term "codswallop" originates from beer sold in Codd bottles. The bottles were regularly produced for many decades, but gradually declined in usage. Since children smashed the bottles to retrieve the marbles, they are relatively rare and have become collector items; particularly in the UK. A cobalt coloured Codd bottle today fetches thousands of British pounds at auction. The Codd-neck design is still used for the Japanese soft drink Ramune and in the Indian drink called Banta. Plastic bottles. Plastic bottles (e.g. two-liter) used for soft drinks can withstand typical internal carbonation pressures of 2–4 bar (30–60 psi.), because the plastic is strain oriented in the stretch blow molding manufacturing process. Aluminum bottles. The aluminum beverage bottle, launched in 2002, also known as a bottlecan, is made of recyclable aluminum with a resealable lug cap that fits onto a plastic sleeve. Some studies have concluded that aluminum provides for increased insulation keeping beverages cooler longer than glass. Capsules. Some jars and bottles have a metal cap or cover called a capsule. They were historically made of lead, and protected the cork from being gnawed away by rodents or infested with cork weevil. Because of research showing that trace amounts of lead could remain on the lip of the bottle, lead capsules (lead foil bottleneck wrappings) were slowly phased out, and by the 1990s most capsules were made of aluminum foil or plastic. |
