Anatomy Origin: Anterior tubercles of the transverse processes of C3 to C6. Insertion: Scalene tubercle and upper surface of the 1st rib. Key Relations: -Deep to sternocleidomastoid. -The brachial plexus and the subclavian artery pass between the anterior scalene and the middle scalene. -The subclavian vein and phrenic nerve passes anterior to the anterior scalene

Anatomy Course Continuation of the brachial vein as it passes the teres major muscle. Along with its corresponding artery it travels through the axilla until it reaches the lateral aspect of the first rib, where it becomes the subclavian vein. Drain Receives superficial veins of the area such as the basilic and cephalic veins. Interested

Anatomy A thickening of the fibrous membrane of the sacroiliac joint capsule. It extends from the anterior lateral surface of the sacrum to the articulating margin of the ilium. The ligament covers the anterior and inferior surface of the sacroiliac joint. Functions Stabilizes the sacroiliac joint. Interested in taking our award-winning Pocket Anatomy app for

Anatomy The axillary nerve arises from the posterior cord of the brachial plexus and exits through the quadrangular space along with the anterior circumflex humeral artery and posterior circumflex humeral vein. Supply Supplies the deltoid, teres minor and triceps brachii (long head), as well as carrying sensory information from the skin covering the inferior region

Anatomy Course Branches off the anterior tibial artery immediately after it has crossed the interosseous space.

Anatomy Course Continuation of the subclavian artery after it passes the lateral margin of the first rib. It passes through the axillary inlet in association with the axillary vein, which is anterior to the artery. Separated into three parts by the pectoralis muscles. Supply Supplies the distal aspect of the arm. Clinical Fracture of the

Anatomy The ligament is part of the proximal tibiofibular joint. It attaches to the anterior surface of the head of the fibula to the anterior surface of the head of the tibia, along the oblique line. Functions To reinforce the proximal tibiofibular joint.

Anatomy Cluster/group of nodes, in armpit. Afferent vessels bring lymph from arm, thoracic walls, breast, upper parts of abdominal walls. Efferent vessels pass filtered lymph on via the Subclavian Trunk to the Lymphatic (Thoracic) Duct; R empties into the R Subclavian Vein, L into L Brachiocephalic (aka Innominate) Vein, each through semilunar valves (which prevent

Anatomy Vermiform (worm-like) blind vestigial sac, 1-8″, arising from 2 cm below ileocecal valve in cecum, right lower quadrant, roughly surface equivalent McBurney’s point (2/3 way from umbilicus to anterior superior iliac spine); base constant but body can lie behind cecum, or in pelvis, or points in between, and can be retroperitoneal. Common site of

Anatomy Course Composed of two different roots of the mandibular nerve, which pass along both sides of the middle meningeal artery. It travels with the superficial temporal artery and vein to the neck of the mandible. It then travels anteriorly to cross the zygomatic process of temporal bone giving off branches along its route.
