Median nerve and medial cords of the brachial plexus, courses through the anterior part of arm, forearm, and hand, and terminates by supplying the muscles of the hand. After receiving inputs from both the lateral and medial cords of the brachial plexus, the median nerve enters the arm from the axilla at the inferior margin of the teres major muscle. It then passes vertically down and courses lateral to the brachial artery between biceps brachii (above) and brachialis (below). At first, it is lateral to the artery and lies anterior to the elbow joint; it then crosses anteriorly to run medial to
Femoral artery on the type of intervention or diagnostic. The site for optimally palpating the "femoral pulse" is in the inner thigh, at the mid-inguinal point, halfway between the pubic symphysis and anterior superior iliac spine. Presence of a "femoral pulse" has been estimated to indicate a systolic blood pressure of more than 50 mmHg, as given by the 50% percentile. The femoral artery can be used to draw arterial blood when the blood pressure is so low that the radial or brachial arteries cannot be located. The femoral artery is susceptible to peripheral arterial disease. When it is blocked through atherosclerosis,
