Cutaneous innervation of the upper limbs is the nerve supply to areas of the skin of the upper limbs (including the arm, forearm, and hand) which are supplied by specific cutaneous nerves. Modern texts are in agreement about which areas of the skin are served by which cutaneous nerves, but there are minor variations in some of the details.
The superficial branch then continues onto the dorsum of the foot to supply sensory fibers to the skin there. The main deep neurovascular bundle at risk is the posterior tibial artery. It lies on the posterior aspect of the tibialis posterior and flexor digitorum longus muscle, and medial to the belly of flexor hallucis longus muscle.
The distal part of the upper limb between the elbow and the radiocarpal joint (wrist joint) is known as the forearm or "lower" arm, and the extremity beyond the wrist is the hand. By anatomical definitions, the bones , ligaments and skeletal muscles of the shoulder girdle , as well as the axilla between them, are considered parts of the upper ...
English: 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. Notice: When the arm is spun so that the thumb point to the outside of the body, meaning the palm of the hand looks forward then it is said the hand is supinated. But ...
The hand (Latin: manus), [5] the metacarpals (in the hand proper) and the phalanges of the fingers, form the metacarpophalangeal joints (MCP, including the knuckles) and interphalangeal joints (IP). Of the joints between the carpus and metacarpus, the carpometacarpal joints , only the saddle-shaped joint of the thumb offers a high degree of ...
A fascial compartment [1] is a section within the body that contains muscles and nerves and is surrounded by deep fascia.In the human body, the limbs can each be divided into two segments – the upper limb can be divided into the arm and the forearm and the sectional compartments of both of these – the fascial compartments of the arm and the fascial compartments of the forearm contain an ...
The peripheral vascular system is the part of the circulatory system that consists of the veins and arteries not in the chest or abdomen (i.e. in the arms, hands, legs and feet). [1] [2] The peripheral arteries supply oxygenated blood to the body, and the peripheral veins lead deoxygenated blood from the capillaries in the extremities back to ...
Neurovascular anatomy [ edit ] Deep to the tendons which form the borders of the anatomical snuff box lies the radial artery , which passes through the anatomical snuffbox on its course from the normal radial pulse detecting area, to the proximal space in between the first and second metacarpals to contribute to the superficial and deep palmar ...
