Because it has long and prominent spinous process.
Because the most distinctive characteristic of this vertebra is the existence of a long and prominent spinous process.
Ventral Arches
C 1, also known as the atlas.
The second cervical vertebra (C2), also called the axis, has a projection on it's superior surface called a dens that creates a pivot joint with the vertebra above it (C1), also known as the atlas. The pivot joint between these two vertebra allows 45 degrees of rotation in each direction, which is half the possible rotation of the head.
The only bones (vertebrae) in your neck are from the spinal column. These are better known as the Cervical vertebra, of which you have seven, medically speaking they are labelled C1 - C7.
a vertebra is more closely defined according to what part of the spine it's in. It may be cervical (neck), thoracic (chest), lumbar (abdomen), or sacral (hips).

Yes the atlas is the first cervical vertebra known as C1.
Most vertebrae have 3 processes. The spinous process, which is the one that comes straight off of your vertebral column, can actually be felt . You can feel this one particularly well at the base of your neck (this is the 7th Cervical vertebra, also known as Vertebra prominens). The very first vertebra, C1, also known at Atlas, does not have a spinous process. Each vertebra has two transverse processes which are on either side of the spinous processes. All of these processes are important for muscle attachments for movement of the head, neck and torso.
Ventral Arches
The odontoid process is found on C2, the second cervical vertebra, also known as the axis.

The occipital condyles "lay on", or articulate with, the lateral masses of the first cervical vertebra, also known as atlas.
The vertebrae in the neck are called cervicle vertebrae. There are 6 of them altogether. The first two (going downward from the skull) are called the atlas and the axis. The rest are just name by their order. Eg: C1 (Atlas), C2 (Axis), C3, C4.....

No, an osteon is the unit of compact bone containing what is known as Haversian canals (series of tubes surrounding and containing the blood vessels and nerve cells that satisfy compact bone)
