The five major regions of the vertebral column are the cervical region, thoracic region, lumbar region, sacrum, and coccyx.
What are the 5 sections of the spine?
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 regions of the spine quizlet?
Typically, the spine is divided into four main regions: cervical, thoracic, lumbar and sacral. Each region has specific characteristics and functions.
What are the spine regions?
The vertebrae are numbered and divided into regions: cervical, thoracic, lumbar, sacrum, and coccyx (Fig. 2). Only the top 24 bones are moveable; the vertebrae of the sacrum and coccyx are fused. The vertebrae in each region have unique features that help them perform their main functions.
What is the lower part of your spine called?
The bottom of the spine is called the sacrum. It is made up of several vertebral bodies usually fused together as one. The remaining small bones or ossicles below the sacrum are also fused together and called the tailbone or coccyx.
What are the 3 areas of the spine?
The spine has three normal curves: cervical, thoracic and lumbar. There are seven cervical vertebrae in the neck, 12 thoracic vertebrae in the torso and five lumbar vertebrae in the lower back.
Which spinal nerves affect which parts of the body?
The nerves of the cervical spine go to the upper chest and arms. The nerves in your thoracic spine go to your chest and abdomen. The nerves of the lumbar spine then reach to your legs, bowel, and bladder. These nerves coordinate and control all the body’s organs and parts, and let you control your muscles.
What are the primary curvatures of the spine?
The vertebral column is curved, with two primary curvatures (thoracic and sacrococcygeal curves) and two secondary curvatures (cervical and lumbar curves).
What are the four regions of the spinal cord?
The spinal cord is divided into four different regions: the cervical, thoracic, lumbar and sacral regions (Figure 3.1).
What are the five regions of the spine in order from top to bottom quizlet?
The five major regions of the vertebral column are the cervical region, thoracic region, lumbar region, sacrum, and coccyx. You just studied 22 terms!
What are the four major regions of the spine and which type of curve is found in each?
Spinal curves are either kyphotic or lordotic. In a normal spine there are four types of spinal curvatures important to balance, flexibility, and stress absorption and distribution.
|Type of Spinal Curves||Curve Description|
|Lumbar Lordosis||40 to 60 degrees|
|Sacral Kyphosis||Sacrum fused in a kyphotic curve|

What absorbs shock in the spine?
The intervertebral discs are soft structures which act as shock absorbers between each of the vertebrae (bones) in the spine. A single disc sits between each vertebra. Each intervertebral disc has a strong outer ring of fibres (‘annulus’), and a soft, jelly-like centre (nucleus).
