Question

each vertebra contacts the one above it via the
o transverse processes.
o pedicles.
o superior articular processes.
o dens.
o lamellae.

Explanation:

In the vertebral - column, each vertebra contacts the one above it via the superior articular processes. The superior articular processes of a vertebra face upward and articulate with the inferior articular processes of the vertebra above it, forming zygapophyseal joints. Transverse processes are lateral projections for muscle and ligament attachment. Pedicles are short, thick processes that connect the vertebral arch to the vertebral body. The dens is a bony projection from the axis (C2) that articulates with the atlas (C1). Lamellae are flat, thin plates in the vertebral arch.

Answer:

superior articular processes.
