Promontory
Openings in the anterior surface of the sacrum where sacral nerves pass
Anterior sacral foramina
Horizontal ridges on anterior surface of sacrum that mark the edges of the fused vertebrae
Transverse lines
Articulate with the inferior facets on L5. Sacrum
Superior articular facets
Rough, raised wall of bone consisting of fused Lamina and articular process of sacral vertebrae. Bumpy, raised ridge
Dorsal wall
Spine of sacrum, projection of fused spines of sacral vertebrae. Most posterior projections
Median crest
Auricular surface of sacrum, ear shaped joint surface for articulation with the os coxae. Lateral
Sacroiliac joint
Vestigial tail/tailbone, 3-5 fused vertebrae
Coccyx
Mature forms from three separate bones: ilium, ischium, and pubis
