What is in between the vertebrae in the back?

The intervertebral discs are flat, round “cushions” that act as shock absorbers between each vertebra in your spine. There is one disc between each vertebra. Each disc has a strong outer ring of fibers called the annulus, and a soft, jelly-like center called the nucleus pulposus.

How many vertebral veins are there?

two vertebral veins
the two vertebral arteries. the two vertebral veins. the anterior spinal artery. the two posterior spinal arteries.

Where is the vertebral vein?

The vertebral vein is a paired vessel found in the transverse foramina of the cervical vertebrae on either side of the neck. It arises at the level of the sixth cervical vertebra from a venous plexus that surrounds the vertebral artery and travels as far as the brachiocephalic veins.

What is located between the bodies of vertebrae?

Intervertebral Discs and Ligaments of the Vertebral Column. The bodies of adjacent vertebrae are strongly anchored to each other by an intervertebral disc. This structure provides padding between the bones during weight bearing, and because it can change shape, also allows for movement between the vertebrae.

What are the lumbar veins?

The lumbar veins are four pairs of blood vessels that drain the lumbar segments of the spinal cord, posterolateral abdominal wall and lumbar structures of the back. They usually empty into the inferior vena cava, but they can also drain into the ascending lumbar, azygos, renal or other lumbar veins.

What is emissary vein?

The emissary veins are valveless vessels which connect the superficial veins of the scalp with deeper veins, e.g. diploic veins of the skull bones. From: Essential Clinical Anatomy of the Nervous System, 2015.

What portions of the vertebrae are located between the bodies and the transverse processes?

The lamina is the part of the vertebra that connects the spinous process and the transverse process. There are two laminae, located on either side of the spinous process.

What is Flavum?

One of a series of bands of elastic tissue that runs between the lamina from the axis to the sacrum, the ligamentum flavum connects the laminae and fuses with the facet joint capsules. … The ligament can become a substantial contributor to spinal stenosis, and is usually removed during a lumbar decompression surgery.

What is the difference between vertebral foramen and intervertebral foramen?

The vertebral foramen provides for passage of the spinal cord. Each spinal nerve exits through an intervertebral foramen, located between adjacent vertebrae.

What is the difference between the cervical thoracic and lumbar vertebrae?

The key difference between cervical thoracic and lumbar vertebrae is their location. Cervical vertebrae are in the neck region while thoracic vertebrae are in the thorax (chest region) and lumbar vertebrae are in the lower back region. … It is a bony segmented structure that runs on the back of the body.

What do you call the fibrocartilage pad between adjacent vertebrae?

An intervertebral disc (or intervertebral fibrocartilage) lies between adjacent vertebrae in the vertebral column. Each disc forms a fibrocartilaginous joint (a symphysis), to allow slight movement of the vertebrae, to act as a ligament to hold the vertebrae together, and to function as a shock absorber for the spine.

What is the name of the second vertebrae?

Axis
Axis (C2) The second cervical vertebra, or axis, supports the dens, or odontoid process, which projects rostrally from the body, serving as a pivotal restraint against horizontal displacement of the atlas.

What is the superior articular facet?

Superior articular facet (facies articularis superior) is a posterior facing, slightly concave surface on the superior articular process. It articulates with the inferior articular facet on the vertebra above.

What is a fibrocartilage?

Fibrocartilage is the tough, very strong tissue found predominantly in the intervertebral disks and at the insertions of ligaments and tendons; it is similar to other fibrous tissues but contains cartilage ground substance and chondrocytes. Elastic cartilage, which is yellow in appearance, is more pliable…

What is the difference between synchondrosis and symphysis?

At a synchondrosis, the bones are united by hyaline cartilage. The epiphyseal plate of growing long bones and the first sternocostal joint that unites the first rib to the sternum are examples of synchondroses. At a symphysis, the bones are joined by fibrocartilage, which is strong and flexible.

Which of the following is a fibrocartilage cartilaginous joint?

symphysis
A cartilaginous joint where the bones are joined by fibrocartilage is called a symphysis (“growing together”).
