What are the 4 curvatures regions of your spine?
There are 33 vertebrae in the human spine that are split into four regions that correspond to the curvature of the spine; the cervical, thoracic, lumbar, sacrum, and coccyx.
What are the names of the 4 regions of the vertebral column?
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. 2).
What are the vertebral curvatures?
The vertebral column is curved, with two primary curvatures (thoracic and sacrococcygeal curves) and two secondary curvatures (cervical and lumbar curves).
What are curvatures of the spine?
At the neck, or cervical level, the normal spine arches slightly inward toward the jaw in a curvature called lordosis. The spine arches out slightly at the chest level (kyphosis), and it curves inward again (lordosis) at lumbar level, or lower back.
What are the 3 main parts of a vertebra?
The normal anatomy of the spine is usually described by dividing up the spine into three major sections: the cervical, the thoracic, and the lumbar spine. (Below the lumbar spine is a bone called the sacrum, which is part of the pelvis). Each section is made up of individual bones, called vertebrae.
What are the 5 sections of the vertebral column?
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 four physiological curvatures of the vertebral column What are their functions?
Curvatures of the Vertebral Column. The adult vertebral column does not form a straight line, but instead has four curvatures along its length – cervical, thoracic, lumbar, pelvic (sacrum/coccyx) (see Figure 6.29). These curves increase the vertebral column’s strength, flexibility, and ability to absorb shock.
What are the four curvatures of the vertebral column and what is their purpose?
What are the primary curvatures of the vertebral column?
What are the two primary curves of the adult vertebral column?
The vertebral column is curved, with two primary curvatures (thoracic and sacrococcygeal curves) and two secondary curvatures (cervical and lumbar curves). The vertebral column originally develops as a series of 33 vertebrae, but this number is eventually reduced to 24 vertebrae, plus the sacrum and coccyx .
What are four functions of the vertebral column?
The vertebral column has four main functions: Protection – encloses and protects the spinal cord within the spinal canal. Support – carries the weight of the body above the pelvis. Axis – forms the central axis of the body.
What are sections of vertebral column curve posteriorly?
thoracic and sacral. 2 sections of the vertebral column that curve posteriorly. cervical. there are 7 of these vertebrae in the bertebral column. thoracic. there are 12 of these vertebrae in the vertebral column. lumbar. there are 5 of these varebrae in the vertebral column. cervical vertebrae.
What is inside the vertebral column?
The spine is a column of vertebrae in the back part of the torso (upper body). It is also called the backbone or vertebral column. There is a spinal canal that runs through the length of the spine. Inside this canal is the spinal cord.
