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 segments of the spine called?

The spine itself has three main segments: the cervical spine, the thoracic spine, and the lumbar spine. The cervical is the upper part of the spine, made up of seven vertebrae (bones). The thoracic is the center portion of the spine, consisting of 12 vertebrae. The lower portion of the spine is called the lumbar spine.

Which segment of the spine is made up of 5 vertebrae?

Lumbar (lower back): Five vertebrae (L1 to L5) make up the lower part of the spine. Your lumbar spine supports the upper parts of the spine. It connects to the pelvis and bears most of your body’s weight, as well as the stress of lifting and carrying items.

What’s the bottom 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.

How many cores does a spine have?

Your spine is made up of three segments. When viewed from the side, these segments form three natural curves. The “c-shaped” curves of the neck (cervical spine) and lower back (lumbar spine) are called lordosis. The “reverse c-shaped” curve of the chest (thoracic spine) is called kyphosis.

How do I protect my waistline?

Ways to protect your back

1. Strengthen your core muscles. Your low back is under the stress of supporting your entire upper body.
2. Stretch. Many back pain problems are caused by tight muscles.
3. Avoid sitting with poor posture.
4. Walk.
5. Lift correctly.
6. Sleep well.
7. Watch your weight.
8. Quit Smoking.

Should your spine be perfectly straight?

Just as the shapes of peoples’ bodies differ, the normal spine varies in size and shape. You may have been told to “stand up straight,” but no one’s spine is perfectly straight. The healthy spine has front-to-back curves (normal cervical lordosis, thoracic kyphosis, and lumbar lordosis).

The 5 sections of the spine or vertebral column are the cervical, thoracic, lumbar and sacrum which includes the coccyx. Cervical spine makes up the neck and has 7 vertebrae. The top two bones are known as the atlas and axis and are different from the others to allow rotation of the skull as well as forwards and backward.

How many vertebrae are there in the spine?

Spine anatomy is divided into 4 major sections, typically defined by the number of vertebrae (the round bones that make up the structure of one’s back bone) in each section. Vertebrae are also sometimes called vertebral bodies. (See Spinal Anatomy Image)

What makes up the L4-L5 segment of the spine?

The L4 vertebra and L5 vertebra, along with the disc in between them, make up the L4-L5 segment. Discs are always labeled for the vertebrae that they lie between, and this is consistent throughout the length of the spine – for the cervical, thoracic and lumbar spine.

Which is the best description of the spine?

Vertebrae Define Sections of the Spine 1 Cervical spine (neck) – comprised of 7 cervical vertebrae (termed C1 to C7), starting with C1 at the top of the spine… 2 Thoracic spine (upper back) – made up of 12 thoracic vertebrae (known as T1 to T12), which are attached to the rib bones… More
