	~~'''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.~~		{{Short description\|An article about the spinalis muscle, part of the erector spinae group}}

	== Spinalis ~~Dorsi~~ ==		==Spinalis==
	The '''~~Spinalis Dorsi~~''' is the ~~smallest and~~ most medial ~~column~~ of muscles in the erector spinae. It is ~~usually blended with~~ the [[~~Semispinalis dorsi~~]].		[[File:Spinalis.png\|thumb\|right\|Diagram of the spinalis muscle]]
			The '''spinalis''' is a muscle located in the back, part of the [[erector spinae]] muscle group. It is the most medial of the three muscles that comprise the erector spinae, the others being the [[longissimus]] and the [[iliocostalis]]. The spinalis muscle is responsible for extending and laterally flexing the [[vertebral column]].

	== ~~Spinalis Cervicis~~ ==		==Anatomy==
	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.~~		The spinalis muscle is divided into three parts:

	~~== Spinalis Capitis ==~~		* '''Spinalis thoracis''': This is the largest and most prominent part of the spinalis muscle. It originates from the spinous processes of the lower thoracic and upper lumbar vertebrae and inserts into the spinous processes of the upper thoracic vertebrae.
	~~The~~ '''Spinalis ~~Capitis~~''' ~~(Biventer cervicis)~~ is ~~usually inseparable~~ from the ~~Semispinalis capitis~~.

	~~== Function ==~~		* '''Spinalis cervicis''': This part is often poorly developed or absent. When present, it originates from the spinous processes of the lower cervical and upper thoracic vertebrae and inserts into the spinous processes of the cervical vertebrae.
	~~The~~ Spinalis ~~muscles are responsible for extending~~ the ~~vertebral column~~ and ~~aiding in~~ the ~~posture and curvature~~ of the ~~spine~~.

	~~== Clinical Significance ==~~		* '''Spinalis capitis''': This part is usually indistinguishable from the [[semispinalis capitis]] muscle. It originates from the spinous processes of the upper thoracic and lower cervical vertebrae and inserts into the occipital bone of the skull.
	~~Injury or strain to~~ the ~~Spinalis muscles can result in back pain or loss~~ of ~~mobility. Treatment typically involves physical therapy~~ and ~~pain management~~.

	== ~~See Also~~ ==		==Function==
	* [[Erector spinae ~~muscles]]~~		The primary function of the spinalis muscle is to extend the vertebral column. It also plays a role in lateral flexion of the spine. The spinalis, along with the other muscles of the erector spinae group, helps maintain posture and stabilize the spine during movement.
	* [[Semispinalis muscles]]
	* [[Spinalis Thoracis]]
	* [[Spinalis Cervicis]]
	* [[Spinalis Capitis]]

	== ~~References~~ ==		==Innervation==
	~~<references />~~		The spinalis muscle is innervated by the [[posterior rami]] of the spinal nerves. These nerves provide the necessary motor signals for muscle contraction and sensory feedback from the muscle.

			==Blood Supply==
			The blood supply to the spinalis muscle is provided by the [[dorsal branches]] of the [[posterior intercostal arteries]] and the [[lumbar arteries]]. These vessels ensure that the muscle receives adequate oxygen and nutrients to function effectively.

			==Clinical Significance==
			Injuries or conditions affecting the spinalis muscle can lead to back pain and impaired movement. Conditions such as [[muscle strain]], [[spinal stenosis]], and [[herniated disc]]s can impact the function of the spinalis and other muscles in the erector spinae group.

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

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

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