What are the vertebrae in your back 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.

What is the difference between the cervical thoracic and lumbar vertebrae?

They are the smaller, lighter vertebrae of your neck. Thoracic spine: The next 12 vertebrae run from your neck down your mid-back. Each forms a joint with your 12 pairs of ribs. Lumbar spine: From your ribs to your sacrum, the lower five vertebrae comprise the lumbar spine.

What is the difference between typical and atypical vertebrae?

The key difference between typical and atypical vertebrae is that typical vertebrae consist of all basic components of a vertebra while atypical vertebrae are the vertebrae that have modified structure due to their position and function.

Which of the lumbar vertebrae is a atypical vertebrae?

L5

What are the features of a typical vertebra?

Parts of a Typical Vertebra A typical vertebra consists of a body and a vertebral arch. The arch is formed by the paired pedicles and paired laminae. Arising from the vertebral arch are the transverse, spinous, superior articular, and inferior articular processes.

What are the features of atypical vertebrae?

Of the cervical vertebrae, the atlas (C1), axis (C2) and vertebra prominens (C7) are considered atypical cervical vertebrae. The atlas (C1) lacks a body or spinous process. It has anterior and posterior arches with lateral masses.

What is the function of the lumbar 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. Many back problems occur in the lumbar spine.

Which of these features is found in a lumbar vertebra?

Distinguishing features of the lumbar vertebrae include a thick and stout vertebral body, a blunt, quadrilateral spinous process for the attachment of strong lumbar muscles, and articular processes that are oriented differently than those found on the other vertebrae.

How many vertebrae does the lumbar spine have?

Lumbar (low back) – the main function of the lumbar spine is to bear the weight of the body. The five lumbar vertebrae are numbered L1 to L5. These vertebrae are much larger in size to absorb the stress of lifting and carrying heavy objects.

How many vertebrae do you have in your back?

33 bones

What happens if spinal cord is damaged?

When the spinal cord is damaged, the message from the brain cannot get through. The spinal nerves below the level of injury get signals, but they are not able to go up the spinal tracts to the brain. Reflex movements can happen, but these are not movements that can be controlled.

What part of the spine controls digestion?

The spinal cord sends nerve signals to all parts of your body, affecting how your digestion functions. The lumbar spine, or lower back, includes the sacrum and is particularly vital in terms of nerve function.

Can a misaligned spine cause bowel problems?

If the vertebrae in the spine are improperly aligned, it can cause a misfire in the signals they send to the nerves of the digestive system, including those in the stomach and intestines. The result is many of the commonly reported digestive ailments we hear about, or experience ourselves.
