What are the 3 sections 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 3 main functions of the spine?

The three main functions of the spine are to:

  • Protect the spinal cord, nerve roots and several of the body’s internal organs.
  • Provide structural support and balance to maintain an upright posture.
  • Enable flexible motion.

What are the different 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.

Does Sofie Dossi have a spine?

Yes, she has a spine. If she didn’t, it’d be very hard for her to stand up straight.

What are the 26 bones of the spine called?

The spine, also known as the vertebral column or spinal column, is a column of 26 bones in an adult body — 24 separate vertebrae interspaced with cartilage, and then additionally the sacrum and coccyx.

What are the names of the 26 vertebrae?

These regions are called the cervical spine, thoracic spine, lumbar spine, sacrum, and coccyx.

What parts of the spine control what 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 first 7 vertebrae called?

The cervical spine is made up of the first 7 vertebrae, referred to as C1-7 (see the images below). It functions to provide mobility and stability to the head while connecting it to the relatively immobile thoracic spine. The cervical spine may be divided into 2 parts: upper and lower. Cervical spine anatomy.

What is the top vertebrae called?


What are the numbers of the vertebrae?

In humans, the vertebral column usually consists of 33 vertebrae, placed in series and connected by ligaments and intervertebral discs. However, the number of vertebrae can vary between 32 and 35. Usually there are 7 cervical, 12 thoracic, 5 lumbar, 5 sacral and 4 caudal (coccygeal) vertebrae.

What are the 5 types of vertebrae?

The spine is split into five regions: the cervical, thoracic, lumbar, sacral, and coccyx. The vertebrae of the sacrum and coccyx are fused, but those of the cervical, thoracic, and lumber regions are free to articulate.

What is the most inferior spinal nerve?

coccygeal nerve

What similarities and differences do you notice between the three major types of vertebrae?

Answer and Explanation: The biggest similarity between the main types of vertebrae is the location where they are found since they are all established on the body’s back, precisely on the midline of the back. The main differences, on the other hand, are related to the size and weight of each of them. 2.

What protects spinal cord?

The brain and spinal cord are protected by bony structures — the skull and spinal column. Meninges are membranes that cover and protect the brain and spinal cord.

What is a vertebra?

Vertebrae. Vertebrae are the 33 individual bones that interlock with each other to form the spinal column. The vertebrae are numbered and divided into regions: cervical, thoracic, lumbar, sacrum, and coccyx (Fig. 2).

What is vertebral foramen?

In a typical vertebra, the vertebral foramen is the foramen (opening) formed by the anterior segment (the body), and the posterior part, the vertebral arch. Within this foramen the spinal cord and associated meninges are housed.

What is the function of a vertebral foramen?

The vertebral foramen is of functional importance since it provides for the passage of the spinal cord and the meninges. This foramen gets progressively smaller as one moves inferiorly.

What passes through vertebral foramen?

A number of structures pass through the foramen. These are the root of each spinal nerve, the spinal artery of the segmental artery, communicating veins between the internal and external plexuses, recurrent meningeal (sinu-vertebral) nerves, and transforaminal ligaments.

What organ is found in the spinal vertebral foramen?

The vertebral foramen houses the spinal cord and its meninges. This large tunnel running up and down inside all of the vertebrae contains the spinal cord and is typically called the spinal canal, not the vertebral foramen.

Which vertebral curvatures are primary and secondary?

The vertebral column is curved, with two primary curvatures (thoracic and sacrococcygeal curves) and two secondary curvatures (cervical and lumbar curves).

Which vertebra has the largest vertebral foramen?


What are the three boundaries of the vertebral foramen?

6 The anatomic boundaries of the foramen consist of the adjacent vertebral pedicles superiorly and inferiorly, the postero-inferior margin of the superior vertebral body, the intervertebral disc, the postero-superior vertebral notch of the inferior vertebral body anteriorly, and the ligamentum flavum and superior and …

How big is the vertebral foramen?

In the present study, the mean diameter of the right transverse foramen varied from 2.54 mm to 7.79 mm in diameter (mean = 5.55 ± 0.87 mm), whereas the mean diameter of left transverse foramen varied from 2.65 mm to 7.35 mm (mean = 5.48 ± 0.77 mm).

What is the difference between vertebral foramen and intervertebral foramen?

The vertebral foramen provides for passage of the spinal cord. The intervertebral foramen is the opening formed between adjacent vertebrae for the exit of a spinal nerve.

What is the vertebral canal?

The vertebral canal, otherwise known as the vertebral cavity or spinal cavity, is an anatomical space formed by the vertebral column that stores an integral portion of the central nervous system: the spinal cord and the spinal nerve roots branching off the spinal cord bilaterally.

What is the function of spinal cavity?

Function of the Dorsal Cavity Like most body cavities, the dorsal cavity protects what’s inside by providing a cushion from damage and impacts with the environment and other organisms. The space around the brain and spinal column is filled with fluid, which acts as a buffer around the structures.

What ligament is inside the vertebral canal?

The posterior longitudinal ligament runs in the spinal canal attaching to the vertebral bodies and vertebral discs and tightens with cervical flexion.

Is Spinal stenosis a permanent disability?

If you have spinal stenosis and it has caused permanent damage and that you will not be able to work anymore and earn a living, then you may be eligible for Social Security disability benefits. Spinal stenosis is located in the Social Security disability blue book under disorders of the spine.

What is the best painkiller for spinal stenosis?

Pain medications such as ibuprofen (Advil, Motrin IB, others), naproxen (Aleve, others) and acetaminophen (Tylenol, others) may be used temporarily to ease the discomfort of spinal stenosis. They are typically recommended for a short time only, as there’s little evidence of benefit from long-term use. Antidepressants.
