Radial nerve arm, and later in the anterior compartment of the arm, and continues in the posterior compartment of the forearm. The radial nerve originates from the posterior cord of the brachial plexus with root values of C5 to C8 and T1. From the brachial plexus, it travels behind the third part of the axillary artery (part of the axillary artery distal to the pectoralis minor). In the arm, it runs behind the brachial artery and then enters the lower triangular space to reach the radial sulcus of back of the humerus. It travel downwards together with profunda brachii atery, between the
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,
