The radial artery arises from the bifurcation of the brachial artery in the antecubital fossa.It runs distally on the anterior part of the forearm. There, it serves as a landmark for the division between the anterior and posterior compartments of the forearm, with the posterior compartment beginning just lateral to the artery.
These terms describe location as palmar and plantar; For example, volar pads are those on the underside of hands or fingers; the plantar surface describes the sole of the heel, foot or toes. Similarly, in the forearm, for clarity, the sides are named after the bones.
It passes down the forearm on the palmar surface of the interosseous membrane. [2]It is accompanied by the palmar interosseous branch of the median nerve, and overlapped by the contiguous margins of the flexor digitorum profundus and flexor pollicis longus muscles, giving off in this situation muscular branches, and the nutrient arteries of the radius and ulna.
The forearm is the region of the upper limb between the elbow and the wrist. [1] The term forearm is used in anatomy to distinguish it from the arm, a word which is used to describe the entire appendage of the upper limb, but which in anatomy, technically, means only the region of the upper arm, whereas the lower "arm" is called the forearm.
The brachioradialis, flexor of the elbow, is unusual in that it is located in the posterior compartment, but it is actually a muscle of flexor / anterior compartment of the forearm. The anconeus, assisting in extension of the elbow joint, is by some considered part of the posterior compartment of the arm.
Forearm: Anterior ulnar recurrent artery, Posterior ulnar recurrent artery, Common interosseous is very short, around 1 cm, and gives rise to the anterior, posterior, and recurrent interosseous arteries and close to the wrist it gives off the palmar carpal branch which is the ulnar contribution to the palmar carpal arch and it also gives a dorsal carpal branch which is the ulnar contribution ...
AIN also has large sensory nerve to the volar wrist bones and compression of the AIN branch of the median nerve at the elbow can cause referred pain in the volar wrist/distal volar forearm. Non-surgical treatment consists of splinting, proximal tissue massage and anti-inflammatory drugs.
the brachial region encompassing the upper arm, the olecranal region encompassing the back of the elbow, the antebrachial region encompasses the forearm, front and back; and the manual or manus region encompassing the back of the hand. The posterior regions of the legs, from superior to inferior, include the gluteal region encompassing the ...
