Anatomy Course An anterior branch of the abdominal aorta that arises at approximately the vertebral level of L1. It descends into the abdomen, passing in front of the left renal vein and the inferior duodenum and passing behind the neck of the pancreas and the splenic vein. It also crosses in front of the uncinate

Anatomy Course Branches from the common peroneal nerve just below the knee joint on the anterolateral side of the leg. It descends towards the foot passing between the peroneus longus and extensor digitorum longus muscles. It then becomes more superficial, piercing through the deep fascia approximately half-way down the leg. It ends in branches which

Anatomy Course A branch of the external carotid artery. It is a terminal branch of the external carotid and is said to begin in the parotid gland. It ascends anterior to the ear and divides into branches that travel in the connective tissue layer of the scalp. Supply Supplies most of the scalp. Interested in

Anatomy Course Begins in a venous plexus on the side of the scalp. It travels through the connective tissue layer of the scalp, to just above the parotid gland, where it unites with the maxillary vein to form the retromandibular vein. Drain Drains the superficial temporal aspect of the scalp. Interested in taking our award-winning

Anatomy Paired structure that forms a superficial elevation on the dorsal side of the rostral midbrain. It is located within the tectum of the midbrain. The superior and inferior colliculi are collectively known as the corpora quadrigemina. Blood Supply: Supplied by branches of the posterior cerebral arteries. Functions Tectospinal fibers arise from the superior colliculus.

Anatomy Origin: Dorsal surface of the ischial spine. Insertion: Blends with the more superior fibres of the tendon of the obturator internus and attaches with the tendon to the medial border of the greater trochanter of the femur. Key Relations: Lies superior to the obturator internus muscle. Functions Working with gemellus inferior and obturator internus,

Anatomy The subdeltoid bursa lies between the tendon of subscapularis and the fibrous membrane of the glenohumeral joint capsule. Functions The subdeltoid bursa reduces friction between the glenohumeral joint and the tendon of the subscapularis muscle. Clinical Bursitis is swelling of the bursa from infection or overuse.

Anatomy Origin: Medial two thirds of the costal surface of the scapula. Insertion: Lesser tubercle of humerus and anterior of capsule of shoulder joint. Key Relations: -Forms much of the posterior axillary wall. -One of the four muscles of the rotator cuff muscle group. Functions -Medially rotates the arm at the glenohumeral joint. -Adducts the

Anatomy Course Branches off from the radial nerve just beyond the lateral epicondyle of the humerus, beneath the brachioradialis muscle. From there it continues to course distally beneath the brachioradialis. Just proximal to the wrist, it emerges from underneath the tendon of the brachioradialis muscle, between it and the tendon of the extensor carpi radialis

Anatomy Course A terminal branch of the ulnar nerve. Supply Supplies the skin on the medial aspect of the palm with sensory innervation. Clinical Damage may result in pain, a tingling sensation or numbness in its region of distribution. Interested in taking our award-winning Pocket Anatomy app for a test drive?
