Which of the following sections of the spinal column have five vertebrae?

Regional Vertebral Characteristics. The vertebrae of the spinal column are divided into five regions: cervical, thoracic, lumbar, sacral, and coccyx.

Hereof, which of the following sections of the spinal column?

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). Only the top 24 bones are moveable; the vertebrae of the sacrum and coccyx are fused.

Subsequently, question is, which is the lowest section of the vertebral column? Inferiorly, C1 articulates with the C2 vertebra, and so on. Below these are the 12 thoracic vertebrae, designated T1–T12. The lower back contains the L1–L5 lumbar vertebrae. The single sacrum, which is also part of the pelvis, is formed by the fusion of five sacral vertebrae.

Keeping this in view, what are the 5 groups of vertebrae?

From top to bottom, the vertebrae are:

Cervical spine: 7 vertebrae (C1–C7)
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 makes up the spinal column?

The human spinal cord is protected by the bony spinal column shown to the left. The spinal column is made up of bones called vertebrae. The spinal cord is located in the vertebral foramen and is made up of 31 segments: 8 cervical, 12 thoracic, 5 lumbar, 5 sacral and 1 coccygeal.

What are the 31 spinal nerves and their functions?

Spinal nerve, in vertebrates, any one of many paired peripheral nerves that arise from the spinal cord. In humans there are 31 pairs: 8 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 1 coccygeal. Each pair connects the spinal cord with a specific region of the body.

What are the 3 main sections of the spine?

The normal anatomy of the spine is usually described by dividing up the spine into three major sections: the cervical, the thoracic, and the lumbar spine. (Below the lumbar spine is a bone called the sacrum, which is part of the pelvis). Each section is made up of individual bones, called vertebrae.

What are the 4 sections of the spine?

Typically, the spine is divided into four main regions: cervical, thoracic, lumbar and sacral.

Which vertebrae controls what?

Cervical spinal nerves, also called cervical nerves, provide functional control and sensation to different parts of the body based on the spinal level where they branch out from the spinal cord.

What is backbone in human body?

The human spine, or backbone, is made up of 33 bones called vertebrae that stretch from the neck to the pelvis and protect the spinal cord. It is divided into five main sections: cervical, thoracic, lumbar, sacrum, and coccyx.

What parts of the body are controlled by the thoracic spine?

Thoracic Spinal Cord Injuries

T-1 through T-5 nerves affect muscles, upper chest, mid-back and abdominal muscles. These nerves and muscles help control the rib cage, lungs, diaphragm and muscles that help you breathe.
T-6 through T-12 nerves affect abdominal and back muscles.

How many bones are in the spinal cord?

33 bones

What nerves are affected by t12?

At T12, the ventral ramus becomes a subcostal nerve that travels beneath the twelfth rib. At T1 through T12, the dorsal ramus goes into the back muscles and also provides sensation to the skin. The motor and sensory functions provided by a thoracic nerve root are determined by its vertebral level.

Where is the 6th vertebrae located?

The C6 vertebra is the sixth cervical vertebra of the spine. It is found in the base of the neck between the C5 and the last cervical vertebra, C7.

What are the characteristics of vertebrae?

They have three main distinguishing features:

Bifid spinous process – the spinous process bifurcates at its distal end.
Transverse foramina – an opening in each transverse process, through which the vertebral arteries travel to the brain.
Triangular vertebral foramen.

How big is a vertebrae?

Usually there are 7 cervical, 12 thoracic, 5 lumbar, 5 sacral and 4 caudal (coccygeal) vertebrae. In humans, the length of the vertebral column is 71 cm in males and 61 cm in females. This diagram shows the curvatures associated with the different regions of the human vertebral column.

What are the 26 vertebrae?

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. Continue Scrolling To Read More Below

How many vertebrae are in the human body?

33 vertebrae

What are the different types of vertebrae?

There are 4 different types of vertebrae:

Cervical vertebrae.
Thoracic vertebrae.
Lumbar vertebrae.
Sacrococcygeal vertebrae.

What is found between individual vertebrae?

The intervertebral discs are flat, round "cushions" that act as shock absorbers between each vertebra in your spine. There is one disc between each vertebra. Each disc has a strong outer ring of fibers called the annulus, and a soft, jelly-like center called the nucleus pulposus.

Do all humans have the same number of vertebrae?

Most people have the same number of vertebrae. The typical number is seven cervical, 12 thoracic and 5 lumbar vertebrae. There are also sacral vertebra analogues which are all typically fused to form the sacrum.

What is vertebral formula?

Vertebral formula is a formula indicating the number of vertebrae in each segment of the spinal column. For humans it is C 7, T 12, L 5, S 7, Co 4 which is equal to 33.

What is a Zygapophyseal joint?

The facet joints, (or zygapophysial joints, zygapophyseal, apophyseal, or Z-joints) are a set of synovial, plane joints between the articular processes of two adjacent vertebrae. There are two facet joints in each spinal motion segment and each facet joint is innervated by the recurrent meningeal nerves.

What are the functions of vertebral column?

The major function of the vertebral column is protection of the spinal cord; it also provides stiffening for the body and attachment for the pectoral and pelvic girdles and many muscles. In humans an additional function is to transmit body weight in walking and standing.
