The cervical vertebra which make up the cervical spine are similar to other vertebra. They are numbered C1-C7.
C1 is formed somewhat differently as it forms a "ring" that supports the skull. It has almost no body. It is called the Atlas. (Atlas carried the world on his back).
C2 has a "tooth" called the dens or odontoid process. The dens sticks up like a finger into the "ring". The two together also allow the head to move. For example, when a person looks to the left or right. C2 is called the Axis.
C3-C6 all are the same. C7 has a projection called the vertebral prominence. This can be felt near the middle between the scapulae. It is a landmark for C7.

Do muscle push bones to make them move?
Muscles never "push"; they can only "pull".
The only power that muscles have is to contract or relax. When they contract, they pull. Most bones have two or more sets of muscles, and each muscle pulls in one direction; in sets, the muscles can work together or oppose each other, which account for all the actions that an animal or person can perform.
Bones have names so that medical professionals can have a precise terminology to use across many medical and therapeutic disciplines.
If you want to know where the nearest pharmacy is then the person answering you will use names of roads and landmarks to guide your way. In much the same way medical professionals need names for all parts of the body including the bones to guide their way when treating illness and injuries.
