Anatomy Vertebrae

Anatomy Back Lumbar Vertebrae Vertebrae along with intervertebral discs compose the vertebral column or spine. Hope you have a basic idea on osteological features of different vertebrae of animal.

The vertebral body is the large anterior cylindrical portion that is.

Anatomy vertebrae. It consists of a sequence of vertebrae singular vertebra each of which is separated and united by an intervertebral disc. The vertebral column is divided into 5 different regions - cervical thoracic lumbar sacrum and coccyx. A normal vertebral column creates a graceful double-S curve when viewed from the side of the body.

Each vertebral discs consist of. Vertebrae separated by intervertebral discs. First second sixth and seventh cervical vertebrae are atypical and rests are typical vertebrae.

The vertebral column houses the spinal canal a cavity that. It is part of the axial skeleton and extends from the base of the skull to the tip of the coccyx. Only the top 24 bones are moveable.

It is a flexible column that supports the head neck and body and allows for their movements. 12 vertebrae of the mid-back T1-T12 Lumbar spine. The pedicles are short thick processes that extend one from each side posteriorly from the junctions of the posteriolateral surfaces of the centrum on its upper surface.

This column supports about half of the weight of the body with the other half supported by the muscles. The first cervical vertebra C1 supports the skull and is named atlas after the Greek titan who held the Earth on his shoulders. Vertebrae are the 33 individual bones that interlock with each other to form the spinal column.

An outer fibrous ring consisting of fibrocartilage called called annulus fibrosus annalus ringlike. Cervical thoracic lumbar sacrum and coccyx Fig. The vertebral arch is formed by a pair of pedicles and a pair of laminae it encloses the vertebral foramen and supports seven processes.

Cervical vertebrae anatomy There are seven cervical vertebrae in most of the animal species first second third foutrth fifth sixth and seventh cervical vertebrae. The spine has several major roles in the body that include the protection of the spinal cord and branching spin. The thoracic spines range of motion is limited due to the many ribvertebrae connections and the long spinous processes.

The cervical vertebrae Latin. Vertebrae apart from those that are atypical have a similar basic structure which can be described as an anterior vertebral body and a posterior neural or vertebral arch. Typical cervical vertebrae are characterized mainly by their small size and the presence of a foramen in each transverse process.

Inner soft pulpy highly elastic substance called the nucleus pulposus pulposus pulplike which is acts as a shock absorber absorbing the impact of the bodys daily activities and keeping the two vertebrae separated 33. The vertebrae are numbered and divided into regions. The vertebral column can be divided into 5 regions.

The body of a typical lumbar vertebra is large and cylindrical typically wider from side to side than from front to back. The vertebral column also known as the backbone or the spine is a column of approximately 33 small bones called vertebrae. Cervical thoracic and lumbar vertebrae in the spinal column.

The vertebral bodies act as a support column to hold up the spine. Two pedicles extend from the sides of the vertebral body to join the body to the arch. Each vertebra in higher vertebrates consists of a ventral body or centrum surmounted by a Y-shaped neural arch.

The spinal cord runs through its center. The vertebral column also known as the spinal column is made up of 33 vertebrae. Vertebrae cervicales are seven vertebrae C1 - C7 forming the cervical part of the vertebral column which extends between the skull and the thorax.

The 7 vertebrae in the neck form the cervical region of the spine. The column runs from the cranium to the apex of the coccyx on the posterior aspect of the body. 5 vertebrae of the lower back L1-L5 Sacrum.

Cervical vertebrae are the thinnest and most delicate vertebrae in the spine but offer great flexibility to the neck. Together the vertebrae and intervertebral discs form the vertebral column. These basic characteristics vary depending on the function of each individual vertebra.

The arch extends a spinous process projection downward and backward that may be felt as a series of bumps down the back and two transverse processes one to either side which provide attachment for muscles and ligaments. By definition the vertebrae are the bones of the spine or backbone that function to protect the spinal cord and support the rest of the body and cranium. 7 vertebrae of the neck C1-C7 C1 is the atlas.

The vertebral column also known as the backbone or spine is part of the axial skeletonThe vertebral column is the defining characteristic of a vertebrate in which the notochord a flexible rod of uniform composition found in all chordates has been replaced by a segmented series of bone. Today I am going to discuss on comparative vertebrae anatomy atlas axis thoracic lumbar and sacrum vertebrae of different animals especially from ox sheep goat horse and dog. Lumbar Vertebrae L1 L5 The lumbar vertebrae graduate in size from L1 through L5.

These vertebrae bear much of the bodys weight and related biomechanical stress. C2 is the axis. It extends from the skull to the coccyx and includes the cervical thoracic lumbar and sacral regions.

The vertebral column spine or backbone is a curved structure composed of bony vertebrae that are interconnected by cartilaginous intervertebral discs. The vertebrae of the sacrum and coccyx are fused. Anatomy of a vertebra The vertebral arch is formed by pedicles and laminae.
