Intertransversarii Muscles

Diagram of the intertransversarii muscles

The intertransversarii are small muscles located in the vertebral column. They are part of the intrinsic muscles of the back and play a role in stabilizing the spine and facilitating lateral flexion.

Anatomy

The intertransversarii muscles are situated between the transverse processes of the vertebrae. They are divided into two main groups based on their location:

Cervical Intertransversarii

The cervical intertransversarii are found in the cervical vertebrae region. They are more developed than their lumbar counterparts and are divided into anterior and posterior groups. These muscles assist in the lateral flexion of the neck.

Lumbar Intertransversarii

The lumbar intertransversarii are located in the lumbar vertebrae region. They are less developed than the cervical intertransversarii and are primarily involved in stabilizing the lumbar spine during movement.

Function

The primary function of the intertransversarii muscles is to stabilize the vertebral column. They also assist in lateral flexion of the spine, allowing for side-to-side bending movements. These muscles work in conjunction with other paraspinal muscles to maintain posture and support the spine during various activities.

Clinical Significance

The intertransversarii muscles can be involved in certain clinical conditions, such as muscle strain or back pain. Dysfunction or injury to these muscles may contribute to instability or reduced mobility of the spine. Physical therapy and exercises targeting the intertransversarii can help in rehabilitation and strengthening of the back muscles.
