Structure of the vertebral column

The vertebrae are divided into three regions. Vertebral column in vertebrate animals the flexible column extending from neck to tail made of bones called vertebrae.

The adult vertebral column consists of 24 vertebrae plus the sacrum and coccyx.

Structure of the vertebral column. The vertebral column spine or backbone is a curved structure composed of bony vertebrae that are interconnected by cartilaginous intervertebral discs. It is part of the axial skeleton and extends from the base of the skull to the tip of the coccyx. The spinal cord runs through its center.

The vertebral column usually consists of 33 vertebrae. 24 presacral vertebrae 7 cervical 12 thoracic and 5 lumbar followed by the sacrum 5 fused sacral vertebrae and the coccyx 4 frequently fused coccygeal vertebrae. The spine or vertebral column consists of 33 vertebral segments divided into 5 regions.

Cervical thoracic lumbar sacral and coccygeal. Normally there are 7 cervical 12 thoracic 5 lumbar 5 sacral and 4 coccygeal segments. The vertebral column is also known as the spinal column or spine Figure 1.

It consists of a sequence of vertebrae singular vertebra each of which is separated and united by an intervertebral disc. Together the vertebrae and intervertebral discs form the vertebral column. The vertebral column is a series of approximately 33 bones called vertebrae which are separated by intervertebral discs.

The column can be divided into five different regions with each region characterised by a different vertebral structure. In this article we shall look at the anatomy of the vertebral column its function structure and clinical significance. The vertebral column spine defines the animal subphylum Vertebra or vertebrates of the phylum Chordata.

In humans it is composed of 33 vertebrae that include 7 cervical 12 thoracic 5 lumbar 5 sacral and 4 coccygeal. Along with the skull ribs and sternum these vertebrae make up. The vertebral column is divided into five main sections and each contains a specific number of vertebrae.

There are 33 vertebrae in total the upper 24 vertebrae are articulating and separated. There are usually thirty-three vertebrae in a humans vertebral column. The top twenty-four articulate and are divided from one another by intervertebral discs while the bottom nine become united in adults five throughout the sacrum and four throughout the coccyx or tailbone.

The vertebral column spine or backbone is a curved structure composed of bony vertebrae that are interconnected by a series of cartilaginous intervertebral discs. The vertebral column can be divided into the cervical thoracic and lumbar vertebrae the sacrum and coccyx. Vertebral column in vertebrate animals the flexible column extending from neck to tail made of bones called vertebrae.

The major function of the vertebral column is to protect the spinal cord. It also is an attachment for many muscles. In humans it further transmits body weight in walking and standing.

The vertebral column consists of 33 vertebrae. 5 fused sacral vertebrae that make up the sacrum. 4 fused coccygeal vertebrae that form the coccyx tail bone.

Before we delve into the different types of vertebral bones its important to understand the structure and features of all vertebral bones. The vertebral column picks up from where the skull ends and goes right down to the lower back. The vertebral column consists of a continuous chain of 33 vertebrae as well as 23 intervertebral discs.

An intervertebral disc is a flattened structure that sits between and cushions vertebrae. Discs are composed of a fibrocartilage ring the annulus fibrosus surrounding a gelatinous center the. The vertebral column forms the neck and back.

The vertebral column originally develops as 33 vertebrae but is eventually reduced to 24 vertebrae plus the sacrum and coccyx. The vertebrae are divided into the cervical region C1C7 vertebrae the thoracic region T1T12 vertebrae and the lumbar region L1L5 vertebrae. What is the vertebral column comprised of.

• forms the major component of the axial skeleton. The vertebral column also known as the backbone or spine is a tall thin bone that runs from the base of the spine to the pelvis and is located dorsally. It protects the spinal cord and serves as a vital connection point for a variety of muscle groups.

The adult vertebral column consists of 24 vertebrae plus the sacrum and coccyx. The vertebrae are divided into three regions. Cervical C1C7 vertebrae thoracic T1T12 vertebrae and lumbar L1L5 vertebrae.

The vertebral column is one of the foundational structures of the human body. Housing the spinal cord this sequence of bones extends from the base of your skull all the way down to the coccyx. Without it our torsos would basically be lumps of flesh with no form.

The design specification for the human vertebral column is the provision of structural stability affording full mobility as well as protection of the spinal cord and axial neural tissues. 1 While achieving these seemingly disparate objectives the spine also contributes to the functional requirements of gait and to the. Vertebral Column Developmental anomalies pathological changes or obesity can enhance the normal vertebral column curves resulting in the development of abnormal or excessive curvatures Kyphosis also referred to as humpback or hunchback is an excessive posterior curvature of the thoracic region.

This can develop when osteoporosis causes weakening and erosion of the anterior portions of.
