Females underarm The underarm (or armpit, axilla, or oxter) is the area on the human body directly under the joint where the arm connects to the shoulder. ... The first portion of the axillary artery is enclosed, together with the axillary vein and the brachial plexus, in a fibrous sheath—the axillary sheath—continuous above with the deep cervical fascia. ... The lateral intermuscular septum extends from the lower part of the crest of the greater tubercle, along the lateral supracondylar ridge, to the lateral epicondyle; it is blended with the tendon of the Deltoideus, gives attachment to the Triceps brachii behind, to the Brachialis, Brachioradialis, and Extensor carpi radialis longus... The medial intermuscular septum, thicker than the lateral intermuscular septum, extends from the lower part of the crest of the lesser tubercle of the humerus below the Teres major, along the medial supracondylar ridge to the medial epicondyle; it is blended with the tendon of the Coracobrachialis, and affords attachment... Opposite the bend of the elbow the tendon of the biceps brachii gives off, from its medial side, a broad aponeurosis, the lacertus fibrosus (aponeurosis of biceps muscle of arm, bicipital fascia) which passes obliquely downward and medialward across the brachial artery, and is continuous with the deep fascia covering...

The antebrachial fascia (or antibrachial fascia) continuous above with the brachial fascia, is a dense, membranous investment, which forms a general sheath for the muscles in this region; it is attached, behind, to the olecranon and dorsal border of the ulna, and gives off from its deep surface numerous intermuscular... In the human wrist there is a sheath of tough connective tissue which envelopes and protects one nerve (median nerve) and tendons, which attach muscles to the wrist and hand bones. ...

Fingers of the human left hand A finger is a type of digit, an organ of manipulation and sensation found in the hands of humans and other primates. ... The flexor retinaculum (transverse carpal ligament, or anterior annular ligament) is a strong, fibrous band, which arches over the carpus, converting the deep groove on the front of the carpal bones into a tunnel, the carpal tunnel, through which the Flexor tendons of the digits and the median nerve pass. ... The anatomical snuff box is a depression on the back of the hand, just beneath the thumb, that is formed by two tendons. ...
