Spine Animals that have a spine are called vertebrates, and animals that don't have one are called invertebrates. Humans have a spine, so we are vertebrates. Many vertebrates, including mammals, have intervertebral discs separating the vertebrae. Regions. The vertebral column is divided by doctors into 5 sections called regions. These 5 regions from top to bottom are: Cervical - Shown in red, this region supports the head. It is made up of 7 vertebrae. The first two, called the atlas and axis, connect the spine to the skull. Thoracic - Shown in blue, this region supports the ribs.

- Just as any other bone in the body, the vertebral column protects the vertebrae which is the one that connects all of your body organs to the brain allowing sending and receiv … ing of impulses.This is also responsible for your posture.he vertebral column does 3 major things. 1. Supports the upper body. 2. Allows for flexibility of the upper body. 3. Houses the spinal cord. It protects and supports the spi … nal cord.

- The vertebral column is composed of a series of 31 separate bones known as vertebrae. There are seven cervical or neck vertebrae, 12 thoracic vertebrae, and five lumbar vertebrae. The sacrum is composed of five fused vertebrae, and there are two coccygeal vertebrae which are sometimes fused (fig.1). In the normal adult there are four curvatures in the vertebral column in an anteroposterior plane. These serve to align the head with a vertical line through the pelvis (fig. 2).he sacrum is composed of five fused vertebrae, and there are two coccygeal vertebrae which are sometimes fused (fig. 1).

- The spine (also called the vertebral column or spinal column) is composed of a series of bones called vertebrae stacked one upon another. There are four regions of the spine: 1  cervical (neck). 2  thoracic (chest/trunk).3  lumbar (low back).he five lumbar vertebral bodies are the weight-bearing portion of the spine and are the largest in diameter compared to the thoracic and cervical vertebral bodies. They sit atop the sacrum, which is formed by five vertebrae fused together into a solid unit.

Atlas The vertebral column, or spinal column, is made up of a total of 33 vertebrae, which are subdivided into five regions: cervical, thoracic, lumbar, sacral, and coccyx.At the cervical region the spinal column is further classified into an upper and lower cervical region.he atlas is one of the two upper cervical vertebrae, also known as C1, which is the topmost vertebra of the spinal column. It is the vertebra that is in contact with the occipital bone, a flat bone located at the back portion of the head.

Vertebrae in the Vertebral Column The cervical spine has seven vertebral bodies (segments). The top two segments are unique: 1  The first cervical segment (called the atlas) is a ring that does not have a vertebral body. 2  It is attached to the second vertebral body (the axis), which acts as a post that the first vertebral ring rotates around.3  Most of the rotation in the neck is located in these top two segments.ll of the vertebral bodies act as a support column to hold up the spine. This column supports about half of the weight of the body, with the other half supported by the muscles. Each area of the spine has some differences in the form and function of vertebral bodies and how they are attached to adjacent structures.

Disco Dance History Disco Dance History. By Gray Miller. Disco dance history is shaped by the music it is named after. This is ironic, as the first thing that comes to most people's minds when they think of disco is the iconic man in the white suit, dark shirt unbuttoned and finger pointing jubilantly into the sky.

- Vertebral Column Overview. The Vertebral column (spinal column) supports the head and encloses the spinal cord. The spinal column is comprised of 26 individual bones, these bones are referred to as vertebrae.The spinal column is divided into 5 different areas containing groups of vertebrae and are grouped as follows:7 cervical vertebrae in the neck. 12 thoracic vertebrae in the upper back corresponding to each pair of ribs. 5 lumbar vertebrae in the lower back.5 sacral vertebrae which are fused together to form 1 bone called the sacrum. 4 coccygeal vertebrae that are fused together to form the coccyx or tail-bone. The vertebrae are referred to by their name and number, counting down from the top of the spinal column as follows:he thoracic vertebrae are T1 - T12. The lumbar vertebrae are L1 - L5. The sacrum and coccyx do not have numbers and each is thought of as one bone. Spinal nerves exit the sacrum and coccyx at levels (Foramen) within the main structure of each vertebra.

Vertebral column In the human vertebral column there are normally thirty-three vertebrae; the upper twenty-four are articulating and separated from each other by intervertebral discs, and the lower nine are fused in adults, five in the sacrum and four in the coccyx or tailbone.

Spinal fractures Spinal column and spinal cord. To understand spinal fractures, it is helpful to understand how your spine works (see Anatomy of the Spine). Your spine is made of 33 bones called vertebrae that provide the main support for your body, allowing you to stand upright, bend, and twist. In the middle of each vertebra is a hollow space called the spinal canal, which provides a protective space for the spinal cord (Fig. 1).

Vertebral Column The cervical spine is further divided into two parts; the upper cervical region (C1 and C2), and the lower cervical region (C3 through C7). C1 is termed the Atlas and C2 the Axis. The Occiput (CO), also known as the Occipital Bone, is a flat bone that forms the back of the head.Atlas (C1).The Atlas is the first cervical vertebra and therefore abbreviated C1. This vertebra supports the skull. Its appearance is different from the other spinal vertebrae.

- Remember, any phylogenetic tree is a part of the greater whole and, as with a real tree, it does not grow in only one direction after a new branch develops. So, simply because a vertebral column evolved does not mean that invertebrate evolution ceased. It only means that a new branch formed.

Vertebrae in the Vertebral Column The vertebral bodies of the lower back are the largest of the spine because they bear the majority of the body's weight. The paired facet joints on the back of the vertebral segments are aligned so that they allow flexion/extension but not a lot of rotation.Most causes of back pain originate in the lumbar spine.he cervical spine has seven vertebral bodies (segments). The top two segments are unique: 1  The first cervical segment (called the atlas) is a ring that does not have a vertebral body. 2  It is attached to the second vertebral body (the axis), which acts as a post that the first vertebral ring rotates around.

- Vertebral column of a goat. The vertebral column, also known as the backbone or spine, is a bony skeletal structure found in vertebrates. It is formed from individual bones called vertebrae (singular: vertebra), which houses the spinal canal, a cavity that encloses and protects the spinal cord.he human vertebral column usually consists of 33 vertebrae; the upper 24 are articulating vertebrae, separated by intervertebral discs and the lower nine are fused, five fused in the sacrum and four in the coccyx.
