vertebral notch(redirected from incisura vertebralis)
one of the two concavities above (superior) and below (inferior) the pedicle of a vertebra; the notches of two adjacent vertebrae (plus the intervertebral disc) form an intervertebral foramen.
Etymology: L, vertebra, joint; OFr, enochier, notch
either of the concavities on the lower or upper border of a vertebral pedicle.
A concavity on the inferior surface of the vertebral arch for transmission of a spinal nerve.
