Identify the target anatomical structure

Using the Skeletal Anatomy and Bone Identification knowledge points

• The question asks for the name of the first cervical vertebra, which is designated as C1.

Evaluate the given options

Using the Skeletal Anatomy and Bone Identification knowledge points

• clavicle: This is the collarbone, part of the pectoral girdle, not a vertebra.
• atlas: This is the specific name for the first cervical vertebra (C1), which supports the globe of the head.
• axis: This is the second cervical vertebra (C2), characterized by the dens (odontoid process) around which the atlas rotates.
• tailbone: This refers to the coccyx, located at the terminal end of the vertebral column.
