TRANSVERSOSPINALIS Meaning and
Definition
-
The transversospinalis is a set of deep muscles located in the back that runs along the vertebral column. It is comprised of three distinct muscles: the semispinalis, multifidus, and rotatores. These muscles play a crucial role in maintaining and supporting the stability and mobility of the spine.
The semispinalis muscle is the most superficial of the transversospinalis muscles. It originates from the transverse processes of the vertebrae and attaches to the spinous processes of the vertebrae above. Its primary function is to extend and rotate the spine.
The multifidus muscle is the second layer of the transversospinalis muscles. It originates from the sacrum and the iliac crest and attaches to the spinous processes of the vertebrae. Its main role is to stabilize and extend the spine, as well as to provide rotational control.
The rotatores muscle is the deepest layer of the transversospinalis muscles. It originates from the transverse process of one vertebra and attaches to the spinous process of the vertebra above. Its primary function is to assist in rotation and stabilization of the spine.
Collectively, the transversospinalis muscles work together to provide strength, support, and flexibility to the vertebral column. They contribute to maintaining proper posture, enhancing spinal stability, and enabling a range of movements, including extension, rotation, and lateral flexion of the spine. Dysfunction or weakness in these muscles can lead to spinal instability, pain, and limited mobility.

Etymology of TRANSVERSOSPINALIS
The word "transversospinalis" is derived from Latin roots.
- "Transverso" comes from the Latin word "transversus", which means "running across" or "lying across".
- "Spinalis" is derived from the Latin word "spina", which means "backbone" or "spine".
Therefore, "transversospinalis" essentially means "lying across the spine" or "running across the spine". The term is used in anatomy to describe a group of muscles that run obliquely across the vertebral column, helping to stabilize and support the spine.
