Anatomy Course Continuation of the femoral vein after it travels beneath the inguinal ligament. Travels briefly with its counterpart artery until it joins with the internal iliac vein and becomes the common iliac vein. Drain Drains the deep veins of the leg.

Anatomy Origin: Inferior margin of the rib above i.e. ribs 1 to 11. Insertion: Superior surface of the rib below i.e. ribs 2 to 12. Key relations: -Muscle fibres run obliquely anteroinferiorly. -Most superficial intercostal muscle. Functions -Moves ribs superiorly during inspiration, thereby expanding the thoracic cavity. -Maintains intercostals spaces during inspiration and expiration. Supply

Anatomy Course Arises after the bifurcation of the common iliac artery. It descends on the psoas muscle until it passes underneath the inguinal ligament, where it is referred to as the femoral artery. Supply Major source for the lower limb. Clinical In renal transplants, the surgeon often attaches the renal artery of the donor’s kidney

Anatomy Origin: Muscular digitations from the external inferior borders of the 5th to 12th ribs. Insertion: Via aponeurosis to the linea alba and the lateral lip of the iliac crest. Key relations: -Largest and most superficial of the three flat abdominal muscles. -Helpful to visualise the directions of the fibres as a putting your hands

Anatomy Course Begins with the fusion of the posterior auricular vein and a portion of the retromandibular vein in the parotid gland. As it descends from the head it perforates the deep fascia until it eventually joins the subclavian vein, lateral to the internal jugular vein. Drain Drains the blood exterior to the cranium.

Anatomy Course Originates from the anterior side of the external carotid artery, where it then rises superiorly through the deep structures of the neck until it reaches the mandible. It then curves around the inferior border of mandible, anterior to the master muscle. From there it undergoes a tortuous path superomedially, where it becomes the

Anatomy One of the intrinsic muscles of the back. Consists of spinalis capitis, cervicus, thoracis. Spinalis capitis: Usually blends with semispinalis capitis. Spinalis cervicis: (Not always present) Origin: Ligamentum nuchae and spinous process of C7 (sometimes T1 to T2). Insertion: Spinous process of axis (C2). Spinalis thoracis: Origin: Spinous processes of L2 toT11. Insertion: Spinous

Anatomy Origin: Junction of middle and distal thirds of ulna and adjacent interosseous membrane. Insertion: Extensor hood of index finger. Key Relations: The tendon of extensor indicis passes under the extensor retinaculum in a compartment with extensor digitorum. One of the six muscles in the deep posterior compartment of the forearm. Functions -Extends index finger

Anatomy One of the intrinsic muscles of the back. Consists of longissimus capitis, cervicus and thoracis. Longissimus capitis: Origin: Transverse process of T1 to T5 and articular processes of C5 to C7 approx. Insertion: Posterior margin of mastoid process. Key Relations: Lies medial to longissimus cervicus. Longissimus cervicis: Origin: Transverse processes of T1 to T5.

Anatomy Origin: Middle half of the anteromedial surface of the fibula and the interosseous membrane. Insertion: Dorsal surface of the base of the distal phalanx of the hallux (big toe). Key Relations: -One of the four muscles of the anterior compartment of the leg. -The extensor hallucis longus tendon crosses anterior to the ankle joint
