Question

For each vertebrae, the laminae

A) are major components of the vertebral arches.
B) are where the ribs attach.
C) lie ventral to the vertebral foramen.
D) occur in two pairs, so there are four of them.

Answer 1

For each vertebrae, the laminae are major components of the vertebral arches, and each vertebra contains two laminae, one on each side.

Step-by-step explanation:

For each vertebrae, the laminae A) are major components of the vertebral arches. The vertebral arch is composed of pedicles and laminae, which together form the posterior roof of the vertebral arch. There are two laminae in each vertebra, one on the right and one on the left. The vertebral arch, including the laminae, surrounds and defines the vertebral foramen, which is the large opening that serves as a passageway for the spinal cord. A single vertebra does not have four laminae, ribs do not attach to laminae, and the laminae lie dorsal, not ventral, to the vertebral foramen.
