What is vertebral column explain with the help of diagram?

Most thoracic vertebrae have two facets located on the lateral sides of the body, each of which is called a costal facet (costal = “rib”). These are for articulation with the head (end) of a rib. An additional facet is located on the transverse process for articulation with the tubercle of a rib. Figure 8.

What is the importance of the vertebra?

The vertebrae protect and support the spinal cord. They also bear the majority of the weight put upon your spine. The body of each vertebra is the large, round portion of bone. The body of each vertebra is attached to a bony ring.

What are the 3 main functions of the vertebrae?

Roles of the spine

• Protect your spinal cord and surrounding structures. This is probably the most important the spinal vertebrae play in the body.
• Provide the foundation for your posture. Without your spinal bones, you would not be able to stand upright.
• Enable you to move and bend.

What’s a vertebral column?

(ver-TEE-brul KAH-lum) The bones, muscles, tendons, and other tissues that reach from the base of the skull to the tailbone. The vertebral column encloses the spinal cord and the fluid surrounding the spinal cord. Also called backbone, spinal column, and spine.

What are the 4 functions of the vertebral column?

The vertebral column provides attachments to muscles, supports the trunk, protects the spinal cord and nerve roots and serves as a site for haemopoiesis.

How do you learn the vertebral column?

You can use a meal-related mnemonic to remember them – imagine a crunchy breakfast at 7 am (7 cervical vertebrae), a tasty lunch at 12 noon (12 thoracic vertebrae), and a light dinner at 5 pm (5 lumbar vertebrae).

What is the purpose of the sacrum?

The sacrum forms the posterior pelvic wall and strengthens and stabilizes the pelvis. Joined at the very end of the sacrum are two to four tiny, partially fused vertebrae known as the coccyx or “tail bone”. The coccyx provides slight support for the pelvic organs but actually is a bone of little use.

What is the spinal main function?

The three main functions of the spine are to: Protect the spinal cord, nerve roots and several of the body’s internal organs. Provide structural support and balance to maintain an upright posture. Enable flexible motion.

What is the spinal column made up of?

The spine is composed of 33 bones, called vertebrae, divided into five sections: the cervical, thoracic, and lumbar spine sections, and the sacrum and coccyx bones. The cervical section of the spine is made up of the top seven vertebrae in the spine, C1 to C7, and is connected to the base of the skull.

What is vertebral column Class 9?

It is also known as the vertebral column. The vertebral column is a part of the axial skeleton, which comprises the skull, ribs and sternum other than the vertebral column. Each vertebra has a central hollow portion, which forms the neural canal through which the spinal cord passes. The spine protects the spinal cord.

What is vertebral column Class 6?

The vertebral column is also known as the backbone or spine and it is the part of the axial skeleton. The vertebral column houses the spinal canal, a cavity that encloses and protects the spinal cord.

What is the function of the vertebral process?

The spinous processes throughout the spine function as a series of levers both for muscles of posture and for muscles of active movement (Standring et al., 2008). Most of the muscles that attach to the spinous processes act to extend the vertebral column.
