There are 31 pairs of spinal nerves:
- Cervical- 8 pair
- Thoracic- 12 pair
- Lumbar- 5 pair
- Sacral- 5 pair
- Coccygeal- 1 pair
Most exit through their intervertebral foramen (openings in between and towards the back of the vertebra of the spinal column), spinal nerves are named according to the vertebrae they exit from.
The first pair of spinal nerves exits between the occipital bone of the skull and the first cervical vertebra.
The Sacral and Coccygeal nerves exit from the sacrum (the five fused vertebrae at the base of the spine) through the sacral foramina (openings or holes on running down along both sides of the sacrum).

The intervertebral foramina provide passageways for?
provide passageways for spinal nerves that proceed between joining vertebrae and connect to the spinal cord.
What are the openings providing for exit of spinal nerves?
Vertebral foramen are the spaces between adjacent vertebrae where the spinal nerves exit the spinal canal.
Openings provide exit of spinal nerves?
The spinal nerves exit from the vertebral column through openings between adjacent vertebrae. These openings, called intervertebral foramina, are located just in front of the facet joints. They exit from what are called intervertebral foramina (foramen means opening).
What openings for exit of spinal nerves?
foramen
What protect the vertebrae?
spinal cordSpinal chord and nerves
What is a network of spinal nerves called?
nerve plexusesThe spinal nerves emerge from the spinal cord at the brain stem, and between each vertebrae.
Why do i have 31 spinal nerves and only 30 spinal bones?
There are 7 cervical vertebrae and 8 cervical spinal nerves. This explains why you have 31 spinal nerves relative to the 30 vertebral bones.
What provides openings for the exit of spinal nerves?
Intervertebral Foramina
What does the verebrae do?
The vertebrae has two major functions: to provide support and to provide protection. The vertebrae helps to provide support by forming the core structure of the body's frame. If you think about it, the vertebrae connects everything (the limbs, head) to each other. The vertebrae also provides protection for the spinal nerves. These nerves are responsible for sending/receiving motor and sensory information to the brain. If these are damaged, paralysis can occur.
The intervertebral foramina provide passageway for the?
spinal nerves
Intervertebral foramina provide passageways for?
Spinal Nerves
What is spondylotic ridging at L5 S1?
Spondylotic ridging found on MRI is when there is calcification of the posterior longitudinal ligament, which runs behind the bodies of vertebrae caudal to cephlad. Neural foramina are the openings in the spinal column where the spinal nerves exit to the periphery.
