Iliocostalis Thoracis
The Iliocostalis Thoracis is a muscle located in the lower back, part of the larger group known as the erector spinae. It plays a crucial role in maintaining posture and supporting the spine during movement. This muscle extends from the lower ribs to the upper ribs and is involved in lateral flexion and extension of the spine.
As a component of the iliocostalis muscle group, the Iliocostalis Thoracis works alongside other muscles like the Iliocostalis Lumborum and Iliocostalis Cervicis. Together, they help stabilize the vertebral column and assist in various activities, such as bending and twisting the torso.
