Anatomy Course Formed by the fusion of the external and internal iliac veins at the brim of the pelvis. Travel briefly before the two common iliac veins fuse together and form the inferior vena cava at the level of L5. Drain Receives the deoxygenated blood of the lower limb and pelvis. Clinical The right iliac

Anatomy Origin: Ischial spine and the pelvic surface of the sacrospinous ligament. Insertion: Lateral margin of the coccyx and related border of the sacrum. Key Relations: -Coccygeus overlies the sacrospinous ligament. -Contributes to the formation of the posterior part of the pelvic diaphragm in association with the levator ani muscles- iliococcygeus (for more information see

Anatomy Course Large branches of the bifurcation of the abdominal aorta at the level of L4. Travels along the inferior edge of the psoas muscles. Supply Responsible for the supply of the pelvis and the lower limb via the femoral artery. Clinical Common area for stenosis due to atherosclerosis; this is more common in the

Anatomy Cartilaginous forward/anterior/sternal prolongations of the ribs, articulating with the sternum, giving the thorax elasticity with strength. Clinical Hyaline cartilage is found on articular surfaces of synovial joints (as a thin covering layer with a smooth surface), providing resilience. Also found in nasal septum, larynx, trachea and bronchi, where it provides elasticity. Costal cartilage has

Anatomy Course A complex network of vessels that originate mostly from the radial artery but also from the ulnar artery via its deep palmar branch.
