Question

Which of these are typical cervical vertebrae?
A. 1,2,7
B. 5,6,7
C. 1,2,3
D. 4,5,6
E. 3,4,5,6

Answer 1

Hint: The thinnest and the most delicate bone of our body are the cervical vertebrae. They support our head and protect the spinal cord. They provide mobility to the head and neck.

Complete Answer:
The seven bones in our neck is called the cervical vertebrae. The top bone is called the atlas to which the head attaches to the neck. The second bone or the axis on which the head and atlas rotates. These are the smallest and can be readily distinguished from the thoracic or lumbar region by the presence of hole through which the vertebral artery, vein and inferior cervical ganglion passes.
The vertebras are named as C1, C2, C3, C4, C5, C6, C7.

 Where C1 does not have any spinous process and in C& the spinous is longer than the others and does not bifurcate. C1, C2, C3 are known as atypical vertebrae which consist of two broad portions. C1 and C2 do not have vertebral bodies.
 C3-C6 is called the typical vertebrae.

Thus the correct answer is (E). 3,4,5,6 are called the typical vertebrae.

Note: The vertebrae C3-C6 are present at the lower section. These spinal bones attach the thoracic spine and help in supporting the head. The C4 is located centrally in the neck region of the spinal column. C3-C5 helps to power diaphragm whereas C6 controls the wrist extension muscles. It also provides support to biceps.
