The second cervical vertebrae is commonly known as the Axis, It forms the pivot upon which C1 rotates. The movement of shaking or rotating the head left and right happens almost entirely at the joint between the atlas(C1) and the axis(C2).
The cervical spine is made up of seven cervical vertebrae. These are numbered(C1-C7) and are the smallest of the true vertebrae. The third through sixth cervical vertebrae have characteristics in common. The first, second, and seventh are considered special cervical vertebrae, and have different characteristics.
In short, the vertebrae protects the spinal chord, provides support to the body as a whole, and serves as a place to which the pectoral and pelvic girdles as well as many muscles attach. from, Rachel; MN
There are normally thirty-three (33) vertebrae in humans, including the five that are fused to form the sacrum (the others are separated by intervertebral discs) and the four coccygeal bones that form the tailbone. The upper three regions comprise the remaining 24, and are grouped under the names cervical (7 vertebrae), thoracic (12 vertebrae) and lumbar (5 vertebrae), according to the regions they occupy. This number is sometimes increased by an additional vertebra in one region, or it may be diminished in one region, the deficiency often being supplied by an additional vertebra in another. The number of cervical vertebrae is, however, very rarely increased or diminished. With the exception of the first and second cervical, the true or movable vertebrae (the upper three regions) present certain common characteristics that are best studied by examining one from the middle of the thoracic region.

Because the neck is relatively fragile compared with the rest of the spine ... and it has that big lump at the top end.
The origins of the latissimus dorsi are: - spinous processes of the lower six thoracic vertebrae - lumbar vertebrae - sacral vertebrae - lower three or four ribs

There is no such thing as a clavicle vertebrae -- do you mean cervical vertebrea? Here are the common names of all three -- clavicle = collar bone. patella = knee cap. cervical vertebrae = neck.
can also occur in the cervical spine. The incidence of cervical disk herniation is most common between the fifth and sixth cervical vertebrae. The second most common area for cervical disk herniation occurs between
There are only 2 cervical vertebrae that have common names: the atlas and the axis, they act as the pivot that allows you to turn your head.
all mammals descended from a common ancestor.
C2 can refer to a few different things, but probably the most common is in reference to the Cervical vertebrae #2.
Infection with the common human papillomavirus (HPV) is a cause of approximately 90% of all cervical cancers.

Yes. The human spine is made up of three parts, the cervical spine(neck), the thoracic(middle), and the lumbar (lower back). The lumbar consists of 5 vertebrae in the average adult human, but may also only have 4 or 6 vertebrae depending on the individual, although this is not as common. There can be sacralization of the 5th lower lumbar resulting in only 4 lumber vertebrae, or a vertebrae of the sacrum where the individual has an extra 6th lumbar vertebrae. While all adults have 7 cervical vertebrae there is much more variation in the thoracic and lumbar vertebrae. The thoracic too may have a 13th vertebrae resulting in an extra rib. And as mentioned before the lumbar may have 4-6 vertebrae depending on the individual.

Cervical spondylosis refers to spondylosis of the cervical vertebrae (Bones of the spine in the region of the neck). Spondylosis refers to changes occurring in the bones ultimately resulting in compression of the nerve roots passing through these regions. The result of the nerve compression is determined by the specific nerve that is compressed. Common features include sharp pain radiating down the region of the upper limb supplied by the specific nerve root affected. Cervical spondylosis is common in older population. It is often due to osteoarthritis resulting in osteophyte formation (abnormal new bone growth) and these osteophytes result in the nerve compression.
