1.The __ provide passageways fro spinal nerves to exit the verebral column and travel to other parts of the body.

Answer:(B) -intervertbral foramina

Neural foramen also called as the intervertebral foramen is the foramina, or opening between every pair of spinal vertebrae. The opening between the adjacent vertebrae provide passage for exit of spinal nerves and travel to other parts of the body. The size of the foramina largely varies between each person depend upon their pathology, spinal loading, and posture. The intervertebral foramina is found in all the three vertebrae are: cervical, thoracic, and lumbar vertebrae. In addition, it also provide passage for:

  • Spinal artery of the segmental artery
  • Communicating veins between the internal and external plexuses
  • Sinu-vertebral nerves and
  • Transforaminal ligaments.

Vertabral foramen is the large hole between the vertebral arch and its body which houses the spinal cord and its meninges.

Transverse vertebrae enable the passage of the vertebral artery and vertebral vein in each cervical vertebra except the seventh.

The vertebral canals also called as spinal cavity or vertebral cavity is formed by the vertebrae which provides the passage of spinal cord. It has the spinal cord within the vertebral column.

A pair of facet joints of each vertebra is called articular facets.
