Question

identify this specific vertebral bone.
answers: a - d
a sacrum
b atlas
c coccyx
d axis

Explanation:

The Atlas (C1 vertebra) is the first cervical vertebra. It has a ring - like structure with large lateral masses. It lacks a body (which is fused with the Axis, C2, forming the dens). The Sacrum is a triangular bone at the base of the spine formed by fused sacral vertebrae. The Coccyx is the small, triangular tailbone. The Axis (C2) has the dens (odontoid process) which articulates with the Atlas. The given image matches the structure of the Atlas.

Answer:

B. Atlas
