INTERTRANSVERSARII MUSCLE Meaning and
Definition
-
The intertransversarii muscle refers to a group of small, deep muscles found in the vertebral column. Specifically, they are located between the transverse processes of adjacent vertebrae. These muscles play a significant role in the stabilization and movement of the spine.
The intertransversarii muscle consists of multiple short fascicles that run obliquely between the transverse processes of the vertebrae. These muscles are arranged symmetrically on both sides of the spine and vary in size depending on the location in the vertebral column.
Functionally, the intertransversarii muscles act as multifidus muscle's stabilizing assistants. Together, they help maintain proper alignment and coordination within the spine while performing movements like bending, rotating, and extending. The contraction of these muscles can provide segmental stability, facilitating the maintenance of proper posture and balance.
Commonly associated with the deep intrinsic muscles of the back, the intertransversarii muscles are innervated by the spinal nerves that correspond to the vertebral levels at which they are located. The precise action and importance of each intertransversarii muscle may vary across the vertebral column due to differences in spinal movement and stability requirements.
Overall, the intertransversarii muscles are integral to the dynamic functioning of the vertebral column, contributing to the stability, flexibility, and smooth coordination of movements in the spine.
Etymology of INTERTRANSVERSARII MUSCLE
The word "intertransversarii muscle" is composed of two parts: "inter-" and "transversarii muscle".
- "Inter-" is a Latin prefix meaning "between" or "among".
- "Transversarii" is the plural of the Latin word "transversarius", which translates to "transverse" or "running across".
- "Muscle" comes from the Latin word "musculus", meaning "little mouse" due to the similarity of certain muscles to little mice.
Thus, the etymology of the word "intertransversarii muscle" suggests that it is a muscle located between or among other transverse muscles.
