What is the name of the hole in the vertebrae where the nerves pass through?
The neural foramen is the opening between every two vertebrae where the nerve roots exit the spine. The nerve roots travel through the foramen to reach the rest of your body. There are two neural foramina between each pair of vertebrae – one on each side.
What is the name of the openings in which individual nerves emerge from the backbone?
Emerging from the spinal cord are 31 pairs of spinal nerves (8 cervical, 12 thoracic, 5 lumbar, 5 sacral and 1 coccygeal). These emerge from the spine though a small opening between adjacent vertebrae, called the intervertebral foramen.
What are the openings in the sacrum called for nerves to travel through called?
The anterior (or pelvic) sacral foramina are openings in the concave anterior surface of the sacrum through which the anterior divisions of the sacral nerves and the lateral sacral arteries pass.
What is the hole in the vertebrae called?
The vertebrae also have a large hole in the back part of the bone, behind the vertebral body, called the spinal canal.
What are the names of the spinal nerves?
- 8 cervical (C1-C8) nerves emerge from the cervical spine (neck)
- 12 thoracic (T1-T12) nerves emerge from the thoracic spine (mid back)
- 5 lumbar (L1-L5) nerves emerge from the lumbar spine (lower back)
- 5 sacral (S1-S5) nerves emerge from the sacrum (the triangular bone at the base of the spine)
What does the spinal cord pass through?
The spinal cord passes through a hole in the center (called the spinal canal) of each vertebra. Between the vertebrae there are discs that act as cushions, or shock absorbers for the spine. Ligaments and muscles help keep the vertebrae in the right position.
What is the space where the spinal nerve roots exit the vertebral column called?
When the vertebrae are stacked on top of each other the pedicle notches form an area called the intervertebral foramen. This area is of critical importance as the nerve roots exit from the spinal cord through this area to the rest of the body.
What are the holes in the sacrum for?
transverse processes of the lower sacral vertebrae, on each side, are a series of four openings (sacral foramina); the sacral nerves and blood vessels pass through these openings. A sacral canal running down through the centre of the sacrum represents the end of the vertebral canal; the functional spinal cord…
Where is the posterior sacral foramina?
Posterior sacral foramina (foramenina sacralia posteriora) are eight irregular shaped openings located lateral to the bodies of the sacral vertebrae. They communicate with the sacral canal and transmit the posterior (dorsal) primary branches (rami) of the sacral nerves.
