SACRUM AND COCCYX: (ANTERIOR VIEW)

sacrum

(sa'krum) [L., sacred]
The triangular bone situated dorsal and caudal from the two ilia between the fifth lumbar vertebra and the coccyx. It is formed of five united vertebrae and is wedged between the two innominate bones, its articulations forming the sacroiliac joints. It is the base of the vertebral column and, with the coccyx, forms the posterior boundary of the true pelvis. The male sacrum is narrower and more curved than the female sacrum.
Synonym: sacral bone See: illustration

Sacrum

The triangle-shaped bone located between the fifth lumbar vertebra and the coccyx that consists of five vertebrae fused together. The sacrum joins on each side with the bones of the pelvis.

os sacrum

; sacrum vertebral column segment forming part of the pelvis and closing the posterior portion of the two halves of the pelvic girdle; formed from fusion of five sacral vertebrae (S1-S5); articulates superiorly with fifth lumbar vertebra (L5), inferiorly with the coccyx, and laterally with hip bones
