What is a vertebral body?
The vertebral body is the main portion of the vertebra. It bears about 80 percent of the load while standing and provides an attachment for the discs between the vertebrae. The front or anterior section of the vertebral body protects the spinal cord and nerve roots.
What is the vertebral body responsible for?
The major function of the vertebral column is protection of the spinal cord; it also provides stiffening for the body and attachment for the pectoral and pelvic girdles and many muscles. In humans an additional function is to transmit body weight in walking and standing.
What forms vertebral bodies?
Intervertebral discs unite the bodies of adjacent vertebrae. The vertebral arch forms the posterior portion of each vertebra. It consists of four parts, the right and left pedicles and the right and left laminae. Each pedicle forms one of the lateral sides of the vertebral arch.
How do you describe the vertebral column?
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 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.
How many vertebral bodies are there?
Vertebrae. Vertebrae are the 33 individual bones that interlock with each other to form the spinal column. The vertebrae are numbered and divided into regions: cervical, thoracic, lumbar, sacrum, and coccyx (Fig.
What are the 33 vertebrae?
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 are the vertebrae called?
The vertebral column, also known as the backbone or spine, is part of the axial skeleton.
What is vertebral column Class 10?
Vertebrae in Human Body: The axial skeleton comprises the vertebral column, often regarded as the backbone skeleton or spine. The spinal canal (backbone skeleton), a cavity that encircles and protects the spinal cord, is housed within the vertebral column. A vertebral column is found in about 50,000 animal species.
What is vertebral column Class 5?
Where is the vertebrae?
The vertebrae are the bony building blocks of the spine. There are seven cervical vertebrae in the neck, twelve thoracic vertebrae in the upper back, and five lumbar vertebrae in the lower back.
What is a vertevertebral body?
vertebral body. noun. anatomy. : the thick, cylindrical, anterior part of a vertebra that bears the weight of the head and trunk, is attached to and articulates with an adjacent vertebral body by an intervertebral disk, and encloses the front part of the vertebral foramen.
What is the centrum of the vertebrae?
The main portion of a vertebra anterior to the vertebral canal, as distinct from the arches. usage note The term “centrum” is frequently erroneously used as a synonym for vertebral body-however, the developmental centrum is less than the body, which also includes parts of the developmental neural arches.
What is an anterior vertebral body?
medical Definition of vertebral body. : the main anterior bony part of a vertebra that consists of the centrum, the ossified posterolateral joints linking the centrum and each half of the neural arch, and part of the neural arch.
What is the cavity of the vertebral body made of?
The cavity of the vertebral body consists of cancellous bone tissue and is encircled by a protective layer of compact bone. Bony structures called pedicles protrude from each side of the vertebral body and join with the laminae to form the vertebral arch.
