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 A shirt'" is a cloth garment for the upper body. Originally an item of underwear worn exclusively by men, it has become in American English a catch-all term for almost any upper-body garment other than outerwear such as sweaters or coats, or undergarments such as bras (the term "top" is sometimes used in ladieswear). In British English, a shirt is more specifically a garment with a collar, sleeves with cuffs, and a full vertical opening with buttons; what is known in American English as a dress shirt. History. The world's oldest preserved garment, discovered by Flinders Petrie, is a "highly sophisticated" linen shirt from a First Dynasty Egyptian tomb at Tarkan, "ca." 3000B.C.: "the shoulders and sleeves have been finely pleated to give form-fitting trimness while allowing the wearer room to move. The small fringe formed during weaving along one edge of the cloth has been placed by the designer to decorate the neck opening and side seam." The shirt was an item of men's underwear until the twentieth century. Although the woman's chemise was a closely related garment to the man's, it is the man's garment that became the modern shirt. In the middle ages it was a plain, undyed garment worn next to the skin and under regular garments. In medieval artworks, the shirt is only visible (uncovered) on humble characters, such as shepherds, prisoners, and penitents. In the seventeenth century men's shirts were allowed to show, with much the same erotic import as visible underwear today. In the eighteenth century, instead of underpants, men "relied on the long tails of shirts... to serve the function of drawers. Eighteenth century costume historian Joseph Strutt believed that men who did not wear shirts to bed were indecent. Even as late as 1879, a visible shirt with nothing over it was considered improper. The shirt sometimes had frills at the neck or cuffs. In the sixteenth century, men's shirts often had embroidery, and sometimes frills or lace at the neck and cuffs, and through the eighteenth century long neck frills, or jabots, were fashionable. Colored shirts begin to appear in the early nineteenth century, as can be seen in the paintings of George Caleb Bingham. They were considered casual wear, for lower class workers only, until the twentieth century. For a gentleman, "to wear a sky-blue shirt was unthinkable in 1860 but had become standard by 1920 and, in 1980, constituted the most commonplace event." European and American women began wearing shirts in 1861, when the "Garibaldi Blouse", a red shirt as worn by the freedom fighters under Giuseppe Garibaldi, became fashionable. Types of shirt. Tops that would generally not be considered shirts: Parts of shirts. Many terms are used to describe and differentiate types of shirts (and upper-body garments in general) and their construction. The smallest differences may have significance to a cultural or occupational group. Recently, (late 20th century) it has become common to use tops to carry messages or advertising. Many of these distinctions apply to other upper-body garments, such as coats and sweaters. Cuffs. Shirts with long sleeves may further be distinguished by the cuffs: Other features. Some combinations are not applicable, of course, e.g. a tube top cannot have a collar. Types of shirting Fabrics. There are main two categories of i.e. Natural Fibre and Man-Made Fibre (Synthetics or Petroleum based). Some of Natural Fibre fabric are 100% cotton, Bamboo, Soya, now Organic Cotton widely used in making shirts of high quality. Synthetics fibre are Polyester, Tencel, Viscose etc. These are easy care fabrics, some times low in cost. Polyester mixed with cotton (Polycotton) and 100% cotton are most used in shirting fabrics. Shirts and politics. Redshirts was the name used by Garibaldi's troops in Italian Unification. In 1920s and 1930s, the fascism choose coloured shirts for made explicit its ideology:
