2.2 Neurovascular system. 2.2.1 Nerve supply. ... The term "upper arm" is redundant in anatomy, but in informal usage is used to distinguish between the two terms.
A neurovascular bundle is a structure that binds ... By Susan Standring, PhD, DSc, Emeritus Professor of Anatomy, Head of Anatomy and Human Sciences, King's College ...
However, in common, literary, and historical usage, arm refers to the entire upper limb from shoulder to wrist. This article uses the former definition; see upper limb for the wider definition. [8] In primates, the arm is adapted for precise positioning of the hand and thus assist in the hand's manipulative tasks. The ball and socket shoulder ...
The anterior compartment of the arm is also known as the flexor compartment of the arm as its main action is that of flexion. The anterior compartment is one of the two anatomic compartments of the upper arm, the other being the posterior compartment. The compartment contains three muscles; the biceps brachii, the brachialis and the ...
The nerve lies at first behind the axillary artery, [4] and in front of the subscapularis, [1] and passes downward to the lower border of that muscle.. It then winds from anterior to posterior around the neck of the humerus, in company with the posterior humeral circumflex artery, [2] through the quadrangular space (bounded above by the teres minor, below by the teres major, medially by the ...
In human anatomy, the cephalic vein (also called the antecubital vein) [1] is a superficial vein in the arm. It is the longest vein of the upper limb. It starts at the anatomical snuffbox from the radial end of the dorsal venous network of hand, and ascends along the radial (lateral) side of the arm before emptying into the axillary vein.
The axillary sheath is a fibrous sheath that encloses the axillary artery and the three cords of the brachial plexus to form the neurovascular bundle. [1] [2] [3] It is surrounded by the axillary fat. [1] [2] It is an extension of the prevertebral fascia of the deep cervical fascia [citation needed] and is continuous with the carotid sheath at ...
Thoracic outlet syndrome (TOS) is a condition in which there is compression of the nerves, arteries, or veins in the superior thoracic aperture, the passageway from the lower neck to the armpit, also known as the thoracic outlet. [1]
