Anatomy Tailbone. Lowest section of spine, made up of 3-5 small vertebrae, often fused. Transition top to bottom of coccyx, from rudimentary to absent pedicles, laminae, transverse and spinous processes. Clinical Articulates with Sacrum above; limited movement. Vignette From Greek for cuckoo, as viewed from side, resembles its beak. Vestigial tail. Interested in taking our

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. It is situated on the base of the metacarpals bones. Supply Supplies the deeper components of the palm. Interested in taking our award-winning Pocket Anatomy app for a test drive?

Anatomy Most noticeable feature – odontoid process (derived from separation and fusion of body C1 with that of C2) rising from upper surface. Also large strong spinous process. C2 has complex articulation with atlas: Pivotal junction with odontoid process at 2 joints – front of odontoid with anterior arch C1, back of odontoid with transverse

Anatomy Medial end of clavicle (which is a long flat bone, elongated s-shape, convex at medial end, concave at lateral) articulates with manubrium of sternum. Clinical The only horizontal long bone (though ordinarily, no marrow), the clavicle acts as a strut, holding scapula in place and free to move on thoracic wall, which in turn

Anatomy Highest vertebra of column of 33. Forms spine/skull joint, along with C2 (axis). C1 has no vertebral body, as it is fused with that of C2 to contribute to formation of odontoid process (or dens). C1 has no spinous process; its absence affords greater range of movement of skull on C1. Superior facets (atlanto-occipital)

Anatomy Lateral end of clavicle (which is a long flat bone, elongated s-shape, convex at medial end, concave at lateral) articulates with acromial process of scapula. Connected to coracoid process below by coracoclavicular ligament. Clinical Clavicula (Latin); little key. First bone to begin ossification (5-6 weeks in embryo), one of last to finish (21-25 years).
