The median nerve is a nerve in humans and other animals in the upper limb. It is one of the five main nerves originating from the brachial plexus. The median nerve originates from the lateral and medial cords of the brachial plexus, [1] and has contributions from ventral roots of C6-C7 (lateral cord) and C8 and T1 (medial cord). [1] [2]
In the human body, the femoral vein is the vein that accompanies the femoral artery in the femoral sheath.It is a deep vein that begins at the adductor hiatus (an opening in the adductor magnus muscle) as the continuation of the popliteal vein.
The medial femoral circumflex artery (with its branches) supplies arterial blood to several muscles, including: the adductor muscles of the hip, gracilis muscle, [1] [3] pectineus muscle, [3] and external obturator muscle. [1] It delivers most of the arterial supply to the femoral head and femoral neck via branches - the posterior retinacular ...
In the palm of the hand, the median nerve is covered by the skin and the palmar aponeurosis, and rests on the tendons of the Flexor muscles.Immediately after emerging from under the transverse carpal ligament the median nerve becomes enlarged and flattened and splits into a smaller, lateral, and a larger, medial portion.
The recurrent branch of the median nerve is also colloquially called the "Million Dollar Nerve", because injury to this nerve during carpal tunnel surgery can lead to a million dollar lawsuit. Injury to this nerve can lead to loss of function of the thumb. Such injury can happen if the flexor retinaculum is transected too radially. The ...
Flexor pollicis brevis: Supplied by recurrent branch of the median nerve and the deep branch of the ulnar nerve; Iliopsoas: Supplied by spinal nerves and femoral nerve; The tongue is a composite muscle made up of various components like longitudinal, transverse, horizontal muscles with different parts innervated having different nerve supply.
The lateral rotator group is a group of six small muscles of the hip which all externally (laterally) rotate the femur in the hip joint.It consists of the following muscles: piriformis, gemellus superior, obturator internus, gemellus inferior, quadratus femoris and the obturator externus.
The obturator nerve passes around the iliac fossa. [2] It is perforated at its inner part by a nutrient canal . Below it there is a smooth, rounded border, the arcuate line , which runs anterior, inferior, and medial.
