Compare the anatomical features of the cervical, thoracic, and lumbar vertebrae that enable identification of these vertebrae.

Comparison should include

• cervical vertebrae (atlas, axis, odontoid process/dens, and transverse foramen)
• thoracic vertebrae (costal facets)
• lumbar vertebrae
• comparative landmarks (vertebral body, spinous processes, transverse processes, lamina, pedicle, intervertebral foramen, superior and inferior articulating facets, and vertebral foramen).

Process/Skill Questions:

• Why is the first cervical vertebra named after the Greek mythological figure Atlas?
• What functional purpose does the transverse foramen serve?
• What other names are used for the facet joints?
