Transverse processes

Transverse processes (pronunciation: trans-verse pro-cess-es) are small bony projections off the right and left side of each vertebrae. The transverse processes provide points of attachment for muscles and ligaments of the spine.

Etymology

The term "transverse processes" is derived from the Latin "transversus" meaning "across" and "processus" meaning "projection".

Anatomy

The vertebrae are the individual bones that interlock with each other to form the spinal column. Each vertebra has several important parts, one of which is the transverse process. The transverse processes are located on either side of the vertebral body and serve as attachment sites for muscles and ligaments of the spine.

Function

The main function of the transverse processes is to provide points of attachment for the muscles and ligaments that move and stabilize the spine. They also serve as levers, increasing the efficiency of these movements.
