The structures of the vertebral column include: Cervical vertebrae, Thoracic vertebrae, Lumbar vertebrae, Atlas, Axis, Vertebra prominens, Intervertebral foramen, Intervertebral disc.
What are the functions and characteristics of the cervical vertebrae?The cervical vertebrae are the first seven vertebrae of the vertebral column located in the neck region. They have several important functions and characteristics.
The cervical vertebrae provide support to the skull and allow for various movements of the head and neck. They possess a unique structure known as the Atlas (C1) and Axis (C2).
The Atlas is the first cervical vertebra that articulates with the skull, while the Axis is the second cervical vertebra that allows rotational movement of the head. This specialized structure enables us to nod and rotate our head.
Furthermore, the cervical vertebrae have small vertebral bodies and bifid (split) spinous processes. The small size of the vertebral bodies allows flexibility and a wide range of motion in the neck. The bifid spinous processes provide attachment sites for muscles and ligaments.
