Coccyx

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 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 Complex 3D/multiplanar structure, the pea-sized glans and shaft (variably hooded by the labia minora and curtained by the upper/anterior junction/commissure of the labia majora) the only distinctly visible surface element. There is also an internal portion of the shaft and a much bigger associated cluster of tissue, some clearly distinguishable anatomically/histologically (such as paired
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 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).
Anatomy Course Arises from the third division axillary artery at the inferior border of the subscapularis muscle. In association with the axillary nerve it travels through the quadrangular space.
