Sacrum – anterior sacral foramina

Sacrum - anterior sacral foramina

Anatomy

Whereas cervical and thoracic vertebrae are distinct and afford passage of nerves through intervertebral foramina created by notches of adjacent pedicles, the fused sacrum retains foramina for this purpose, front and behind, at the lateral ends of ridges which are remnants (after fusion) of planes of separation of sacral vertebrae.
