What are the 4 main parts of each vertebra?
It protects the spinal cord and is an important attachment point for many muscle groups. There are 33 vertebrae in the human spine, divided into four sections corresponding to the curves of the spine: cervical, thoracic, lumbar, sacral, and coccygeal.
What are the 4 sections of the vertebrae?
The vertebrae are numbered and divided into sections: cervical, thoracic, lumbar, sacral, and coccygeal (Fig. 2). Only the upper 24 bones are mobile, the vertebrae of the sacrum and coccyx are fused. The eddies in each area have unique properties that help them perform their main functions.
What are the main components of the vertebrae?
Cervical, thoracic and lumbar spine
Each vertebra consists of an anterior vertebral body, posterior articular facets, and pedicles that connect the vertebral body to the articular facets.
What are the 4 main curvatures of the vertebrae?
There are four natural curves in the spine. Cervical, thoracic, lumbar and sacral curvature.
What are the 3 parts of each vertebra?
The normal anatomy of the spine is usually described by dividing the spine into three main sections: the cervical spine, the thoracic spine, and the lumbar spine. (Below the lumbar spine is a bone called the sacrum, which is part of the pelvis.)
What are the 4 main parts of each vertebra?
It protects the spinal cord and is an important attachment point for many muscle groups. There are 33 vertebrae in the human spine, divided into four sections corresponding to the curves of the spine: cervical, thoracic, lumbar, sacral, and coccygeal.
What are the divisions of the vertebrae?
The spinal column is made up of 33 bones called vertebrae, which are divided into five sections: cervical, thoracic, lumbar, sacral, and coccygeal. The cervical spine is made up of the first seven vertebrae of the spine, C1 through C7, and connects to the base of the skull.
What is the fourth section of the column called?
There are usually thirty-three vertebrae in the human spine. The upper 24 presacral vertebrae are articulated and separated from each other by intervertebral discs, while the lower nine in the adult are fused, five in the sacrum and four in the coccyx or coccyx.
How many divisions does a vertebra have?
Vortex. As mentioned above, our vertebrae are numbered and divided into five sections: cervical, thoracic, lumbar, sacral, and coccygeal. ten
What are the 4 types of vertebrae?
The vertebrae are 33 individual bones that, when joined together, form the spine. The vertebrae are numbered and divided into sections: cervical, thoracic, lumbar, sacral, and coccygeal (Fig. 2). Only the upper 24 bones are mobile, the vertebrae of the sacrum and coccyx are fused.
What is the curvature of the spine?
Normally, the spine has an S-shaped curvature when viewed from the side. This shape ensures even weight distribution and freedom of movement. The spine curves as follows: The cervical spine curves slightly inward, sometimes described as a posterior C-curve or lordotic curve.
What are the four curvatures of the spine and what do they do?
spinal curvature. The spinal column of an adult does not form a straight line, but has four curves along its length: cervical, thoracic, lumbar, pelvic (sacrum/coccyx) (see Fig.6.29). These curves increase the strength, flexibility and cushioning capacity of the tips.
What are the main curvatures of the vertebrae?
The spinal column has four curves: cervical, thoracic, lumbar, and sacrococcygeal. Thoracic and sacrococcygeal flexions are the primary flexions preserved from the original fetal flexion. The cervical and lumbar curves develop after birth and are therefore secondary curves.
