Intervertebral Foramina
foramen
Spinal nerves exit the vertebral column through small openings called intervertebral foramina located between adjacent vertebrae.
Vertebral foramen are the spaces between adjacent vertebrae where the spinal nerves exit the spinal canal.
Spinal nerves exit the vertebral column through small openings called intervertebral foramina. Once they have exited, these nerves carry sensory information from the body to the spinal cord and transmit motor signals from the spinal cord to the muscles, allowing for movement and sensation.
cervical spinal nerves, thoracic spinal nerves, lumbar spinal nerves, sacral 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).

There are 31 pairs of spinal nerves:Cervical- 8 pairThoracic- 12 pairLumbar- 5 pairSacral- 5 pairCoccygeal- 1 pairMost 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 cranial nerves exit from the brainstem. They emerge from specific openings in the skull called foramina, which are small bony passageways. These openings provide a pathway for the cranial nerves to exit the skull and innervate different parts of the head and neck.
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.
There are 31 pairs of nerves that leave the central nervous system - 12 pairs of cranial nerves that exit from the brain and 31 pairs of spinal nerves that exit from the spinal cord.
The spinal nerves that exit the vertebral column through lateral openings or gaps between the vertebrae are called "intervertebral foramina." These foramina allow the spinal nerves to branch off from the spinal cord and extend to various parts of the body, facilitating communication between the central nervous system and peripheral nervous system. Each pair of spinal nerves corresponds to a specific segment of the vertebral column.
