Spinalis

From WikiMD's Wellness Encyclopedia

(Redirected from Spinalis muscle)

Spinalis is a portion of the Erector spinae, a bundle of muscles and tendons, located nearest to the spine. It is divided into three parts: Spinalis dorsi, Spinalis cervicis, and Spinalis capitis.

Spinalis Dorsi[edit | edit source]

The Spinalis Dorsi is the smallest and most medial column of muscles in the erector spinae. It is usually blended with the Semispinalis dorsi.

Spinalis Cervicis[edit | edit source]

The Spinalis Cervicis (Spinalis colli) is an inconstant muscle, which arises from the lower part of the ligamentum nuchae, the spinous process of the seventh cervical, and sometimes from the spinous processes of the first and second thoracic vertebrae, and is inserted into the spinous process of the axis, and occasionally into the spinous processes of the two vertebrae below it.

Spinalis Capitis[edit | edit source]

The Spinalis Capitis (Biventer cervicis) is usually inseparable from the Semispinalis capitis.

Function[edit | edit source]

The Spinalis muscles are responsible for extending the vertebral column and aiding in the posture and curvature of the spine.

Clinical Significance[edit | edit source]

Injury or strain to the Spinalis muscles can result in back pain or loss of mobility. Treatment typically involves physical therapy and pain management.
