The vertebrae are the backbones. The cervical vertebrae are at the top. The skull rests on and turns on the first cervical vertebra, called "C1". C1 is tied to the second cervical vertebra, called "C2", which allows, the head to turn far to each side by a special arrangement of bone and ligaments.
C3, C4, and C5 are regular vertebrae, but smaller than those further down the spine.
What else can I help you with?
What bone feature of the second cervical vertebrae articulates with the first cervical vertebrae?
The odontoid process, also known as the dens, is the bone feature of the second cervical vertebrae that articulates with the first cervical vertebrae. This connection forms the atlantoaxial joint, which allows for rotation of the head.
Which cranial bone houses the condyles that articulate with first cervical vertebra?
The occipital condyles of the occipital bones articulate with the first cervical vertebra.
Which vertebra articulates with the occipital bone?
The first cervical vertebra, called C1 or the atlas, articulates with the occipital bone.
What is the bone that support the skull?
The bone that supports the skull is the atlas, which is the first cervical vertebra. It sits directly below the skull and allows for the nodding motion of the head. The atlas articulates with the occipital condyles of the skull, providing a crucial connection between the head and the spinal column.
Does the atlas bone have spinous process?
No it doesn't. The atlas is the first cervical vertebra and the only one with no spinous process.
How many sections in the spinal column?
There are three parts: cervical which is at the top, thoracic which is in the middle, and the lumbar which is at the bottom. There could be five parts if you count the sacrum and the coccyx (tail bone) which are at the way bottom or the spinal column.
Which part of the vertebral column has one more pair of nerves coming from it than it has vertebra?
The cervical region of the vertebral column has one more pair of nerves than vertebrae. There are seven cervical vertebrae (C1 to C7) but eight pairs of cervical nerves (C1 to C8). This occurs because the first pair of cervical nerves exits above the first cervical vertebra, while the remaining pairs exit below their corresponding vertebrae.
What movement is most likely to occur in the cervical vertebral column?
how migth bifid spinous process of cervical vertebrae affect anterior-posterior movement in the cervical region of the vertebrae column
What is the name of the superior concave curve in the vertebral column?
The superior concave curve in the vertebral column is called the cervical lordosis.
Divisions of the back bone?
The three main divisions of the spinal column are the cervical spine near the neck, the thoracic region of the upper back, and the lumbar spine in the lower back.
What does the vertebral column support?
The axis supports the weight of the head.
How many bone in vertical column?
There are 33 vertebrae in the human spinal column: 7 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 4 coccygeal vertebrae. These bones are stacked on top of each other to form the spine.
