Because the neck is relatively fragile compared with the rest of the spine ... and it has that big lump at the top end.
The neck doesn't have as much protection as the other sections of the vertebral column.
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.
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).
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.

the most common area that gets dislocated in the body is the shoulder.
The most common causes include complications of the progressive, degenerative spinal disease called spondylosis, as well as traumatic injury to the cervical spine, such as fractures or dislocations.

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.
Compression fractures are most common along the spine involving the vertebrae. This is when a bone in the spine collapses and is most commonly found in the thoracic area of the spine.
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.
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).
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.
