Interspinales muscles

Interspinales muscles are a group of small muscles located in the human body, specifically in the spinal column. They are part of the deep muscles of the back and are situated deeply in the back, between the spinous processes of the vertebrae.

Etymology

The term "Interspinales" is derived from Latin, with "inter" meaning between and "spinales" referring to the spine. Thus, the name directly refers to the location of these muscles, which is between the spinous processes of the vertebrae.

Structure

The Interspinales muscles are divided into two groups: the Interspinales cervicis and the Interspinales lumborum. The Interspinales cervicis are located in the neck region, while the Interspinales lumborum are found in the lumbar region of the spine.

Function

The primary function of the Interspinales muscles is to assist in the extension and rotation of the vertebral column. They also play a role in maintaining posture and stabilizing the spine.

Clinical significance

Due to their deep location, the Interspinales muscles are not commonly injured. However, they can be affected by conditions that impact the spinal column, such as spinal stenosis or herniated disc.
