The five regions of the spine include: cervical, thoracic, lumbar, sacral, and coccygeal. The spine includes four normal curves. As viewed from the side, the thoracic and sacral curves are convex posteriorly, and the lumbar and cervical curves are concave posteriorly.
What are 5 regions of the spine?
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 are the curves of the spine and where are the different curves?
|Type of Spinal Curves||Curve Description|
|Cervical Lordosis||20 to 40 degrees|
|Thoracic Kyphosis||20 to 40 degrees|
|Lumbar Lordosis||40 to 60 degrees|
|Sacral Kyphosis||Sacrum fused in a kyphotic curve|
What are the five regions of the spine quizlet?
The five major regions of the vertebral column are the cervical region, thoracic region, lumbar region, sacrum, and 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.

What are the terms for the 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.
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).
How much curve in spine is normal?
While a normal spine curve at the thoracic region should be within 20 to 50 degrees, kyphosis forces a curve greater than 50 degrees. Patients experience moderate back pain and fatigue. With kyphosis, the curvature forces the body to hunch over and appear as if you are lounging.
What is the difference between the spinal column and the spinal cord?
The spine is made up of a column of bones called vertebrae (spinal column). The spinal cord, a long, fragile structure contained in the spinal canal which runs through the centre of the spine, is protected by the vertebrae.
What are the three pairs of Funiculi in the spinal cord?
The white matter forming the ascending and descending spinal tracts is grouped in three paired funiculi, or sectors: the dorsal or posterior funiculi, lying between the dorsal horns; the lateral funiculi, lying on each side of the spinal cord between the dorsal-root entry zones and the emergence of the ventral nerve …
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.
