What are the 5 regions of the vertebrae called?
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 last 5 vertebrae called?
Thoracic spine: 12 vertebrae (T1–T12) Lumbar spine: 5 vertebrae (L1–L5) Sacrum: 5 (fused) vertebrae (S1–S5) Coccyx: 4 (3–5) (fused) vertebrae (Tailbone)
What is the middle of your back called?
The upper and middle back (called the thoracic spine) has: 12 vertebrae. These bones attach to your rib cage. They make up the longest part of your back.
Sacrum
Thoracic spine: 12 vertebrae (T1–T12) Lumbar spine: 5 vertebrae (L1–L5) Sacrum: 5 (fused) vertebrae (S1–S5) Coccyx: 4 (3–5) (fused) vertebrae (Tailbone)
What are the sections of the spine called?
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.
Where is the C spine?
The cervical spine is made up of the first seven vertebrae in the spine. It starts just below the skull and ends just above the thoracic spine. The cervical spine has a lordotic curve (a backward C-shape) – just like the lumbar spine.

What are the names of the bones in the spine?
The 26 bones of spine are called vertebrae. The first 5 bones of spine are known as the cervical vertebrae, the next 12 bones are known as the thoracic vertebrae followed by 5 lumbar vertebrae and then one fused sacral and a coccyx at the last.
What are the different regions of the spinal cord?
Spinal nerves arise from different regions of the vertebral column and are named accordingly, the regions are – Neck, chest, pelvic and abdominal. Cross-section of spinal cord displays grey matter shaped like a butterfly surrounded by a white matter.
How many vertebrae are there in the spine?
The spine protects the spinal cord. Our spine consists of twenty-six vertebrae. Actually, there are 33 vertebrae in total, but the five sacral and four coccygeal vertebrae are fused together, so taken as one each.
Which is the most delicate region of the spine?
There are 5 major regions of the spine: Cervical: The 7 vertebrae in the neck form the cervical region of the spine. Cervical vertebrae are the thinnest and most delicate vertebrae in the spine but offer great flexibility to the neck. Thoracic: The 12 vertebrae in the chest region form the spine’s thoracic region.
What are the four regions of the spine?
Regions of the Spine. Anatomically, the spine is divided into four regions: The top seven vertebrae that form the neck are called the cervical spine and are labeled C1-C7. The upper back, or thoracic spine, has 12 vertebrae, labeled T1-T12. The lower back, or lumbar spine has five vertebrae, labeled L1-L5.
What are the names of the vertebrae in the spine?
This region consists of seven vertebrae, which are abbreviated C1 through C7 (top to bottom). These vertebrae protect the brain stem and the spinal cord, support the skull, and allow for a wide range of head movement. The first cervical vertebra (C1) is called the Atlas. The Atlas is ring-shaped and it supports the skull. C2 is called the Axis.
What are the three curves of the spine?
When viewed from the side, the normal spine has three gradual curves: The neck has a lordosis; it curves toward the back. The thoracic spine has a kyphosis; it curves toward the front. The lumbar spine also has a lordosis. These curves help the spine to support the load of the head and upper body, and maintain balance in the upright position.
There are 5 major regions of the spine: Cervical: The 7 vertebrae in the neck form the cervical region of the spine. Cervical vertebrae are the thinnest and most delicate vertebrae in the spine but offer great flexibility to the neck. Thoracic: The 12 vertebrae in the chest region form the spine’s thoracic region.
