Transverse process

Transverse process is a small bony projection off the right and left side of each vertebrae of the spine in the human body. The two transverse processes of each vertebrae serve as the point of attachment for muscles and ligaments of the spine as well as the point of articulation for the ribs (in the thoracic spine).

Anatomy

The transverse process is a bony protrusion from the back of a vertebrae. It projects laterally and towards the back from the junctions of the pedicles and laminae. These processes function as levers for the muscles of the spine and for the ligaments. In the thoracic region, the transverse processes also serve as the points of attachment for the ribs.

Function

The transverse processes have three main functions:

• They serve as points of attachment for the muscles that move the spine.
• They function as levers, increasing the spine's range of motion.
• In the thoracic region, they serve as attachment points for the ribs, helping to stabilize the spine.

Clinical significance

Injuries or fractures to the transverse processes can be caused by severe trauma or stress to the spine. These injuries can cause pain and limit mobility. Treatment typically involves pain management and physical therapy.
