What is the vertebrae of the axis?
The vertebral axis is the bone of the cervical spine in the throat. Secondly, it is located under the Atlas bone, which supports the weight of the head. Other names for axes include C2 for its location; Epistropheus, his scientific name; and dentata vertebrae, for an unusual bone protrusion that projects up from the vertebral body as a tooth and is therefore known as DENS. His spinus processes, backward design of bone protrusions on the back of the bone, which are shaped as a whale story, angle slightly down and serve as a point of attachment for the muscles of spinalis and semispinalis cervicis in the upper back. Both play a role in bending the head laterally or bending to one side and when the uterine part is extended, the spinal column.
As well as other cervical vertebrae, the vertebrae also has a few transverse processes, minor prominence on both sides of the vertebra that acts as a place of connection for a number of muscles. These include the muscles of Scalene, Splenius and Longissimus in the throat. Because these muscles stretch from the axis to attach to other points alongThe spine, allows the spine movement, especially rotation and lateral head and neck flexion.
One of the distinctive features of the axis vertebra is DENS, also known as the odontoid process. The odontoid process is so known for its similarity to the tooth, what allows the atlas to rotate around the axis, causing the head to turn. This bone protrusion protrudes vertically from the front of the body axis and articulates with the inner surface of the front arch of the atlas, where it is held in place its back side with a transverse atlantal ligament. Thanks to this and several other bonds holding the lair in place, articulation, swivel joint, it is well fortified and allows limited head rotation on the neck.
Another anatomical structure on the vertebrae, which is characteristic of its unique function, is a few excellent articulated surfaces, one on both sides of the front segment of the vertebral body. Excellent articulated surfaces, set at the top of the vertebralAbout the bodies above the transverse processes are somewhat shaped beans and slightly convex. In this way, they are shaped because they are articulated with the concave lower surfaces of the side materials on the atlas higher to create lateral axial joints, one on both sides. This articulation between the vertebrae of the axis and the atlas is a synovial gliding joint, which means that these two almost flat surfaces can slide each other to a very small extent.
