Anatomy Most curved, usually shortest (sometimes 12th shorter). Only rib whose posterior/vertebral articulation is with only 1 vertebra (T1). Only rib whose anterior/sternal articulation is entirely with manubrium (lateral extremity of the arm of the cruciform – ross-shaped – manubrium. Clinical Ordinarily there are 12 ribs, sometimes 11, this number added to if there are

Anatomy Origin: Spinous process of axis. Insertion: Middle third of inferior nuchal line. Key Relations: Forms the superior and medial border of the suboccipital triangle. Functions -Acts bilaterally to extend the head at the atlanto-occipital joint. -Acts unilaterally to rotate the head to the same side at the atlanto-occipital joint. Supply Innervation: Suboccipital nerve (C1).

Anatomy Origin: posterior tubercle of atlas. Insertion: From foramen magnum to medial third of inferior nuchal line. Functions Acts bilaterally to extend the head at the atlanto-occipital joint. Supply Innervation: Suboccipital nerve (C1). Blood supply: Muscular branches of vertebral artery. Clinical Slips of the muscle attach to the spinal dura and may be involved in

Anatomy Origin: Straight head: anterior inferior iliac spine. Reflected head: a groove on the upper surface of the acetabulum and from the fibrous capsule of the hip joint. Insertion: Base of the patella via the quadriceps femoris tendon. The quadriceps femoris tendon is functionally continuous with the patellar ligament which runs from the apex of

Anatomy Course The renal arteries branch directly from the abdominal aorta at approximately vertebral level L1-L2. The right renal artery is longer and must pass behind the inferior vena cava to reach the right kidney. The left renal artery usually originates slightly higher. Both travel horizontally and retroperitoneally to their respective kidneys. Supply Supply blood

Anatomy Course Begin at the hilums of the kidneys, running horizontally and retroperitoneally to the inferior vena cava. They drain into the inferior vena cava at the approximate vertebral level of L2. Because the left renal vein is longer, and must cross the aorta, it receives a number of tributaries, such as the left phrenic
