NEET PG DENTAL EXAM

Detailed explanation-1: -The atlas (C01) and axis (C02) are two of the most important vertebrae in the spine. Without them, head and neck movement would be impossible.

Detailed explanation-2: -The C1 vertebra, also called atlas, is shaped like a ring. The C2 vertebra has an upward-facing long bony process called the dens. The dens forms a joint with the C1 vertebra and facilitates its turning motions, thereby allowing the head to turn in different directions. The atlantoaxial joint.

Detailed explanation-3: -The first two cervical vertebrae are specialized for articulating with the skull. The atlas (C1) lacks a body and spinous process, and its superior articulating processes (facets) articulate with the occipital condyles of the skull, permitting the head movement used in nodding “yes".

Detailed explanation-4: -The C1 vertebrae is named atlas and the C2 vertebrae is named axis. As well as protecting the spinal cord, these vertebrae are primarily responsible for facilitating and controlling the large range of movement that your neck has, and supporting the considerable weight of your skull at the tip of your spine.
