Explanation:

Identify the anatomical structure

The image shows a model of a single vertebra. A blue label with the number "3" is placed on the long posterior projection extending backward from the vertebral arch.

Determine the specific feature

In Skeletal Anatomy, this prominent posterior projection is the spinous process. We are looking at a lateral view of a vertebra where the spinous process is clearly highlighted by the label.

Relate to anatomical models

Using Anatomical Models to study bones helps identify key landmarks. The spinous process serves as an attachment point for muscles and ligaments.

Answer:

Spinous process
