Is semispinalis the same as spinalis?
Sitting deep to semispinalis thoracis are the rotatores and levatores costarum, while superficially it is covered by the spinalis thoracis (erector spinae group). Just like all the spinotransverse muscles, semispinalis thoracis is innervated by the medial branches of the posterior rami of adjacent spinal nerves.
What are the 3 spinalis muscles?
Spinalis is the most medial of the three erector spinae muscles. Like the other two, it is made up of three parts. Spinalis and longissimus both have capitis, cervicis and thoracis parts, while iliocostalis has cervicis, thoracis and lumborum parts.
What are the spinalis muscles?
spinalis muscle, any of the deep muscles of the back near the vertebral column that, as part of the erector spinae (sacrospinalis) muscle group, assist in extension (e.g., bending backward), lateral flexion (bending to the side), and rotation of the spine.
What does the spinalis thoracis attach to?
The spinalis thoracis is the thoracic part of the spinalis muscle that attaches to thoracic vertebral spinous processes and continues forward as spinalis cervicis. Action: Extends the neck; in unilateral action to raise the neck obliquely and turn it to one side.
How many spinalis muscles are there?
The 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….

(Entry 1 of 2) : the most medial division of the sacrospinalis situated next to the spinal column and acting to extend it or any of the three muscles making up this division: a : spinalis thoracis.
What is spinalis anatomy?
The spinalis is the body’s most medial, or closest to the midline of the body, deep back muscle and originates at the spinous processes (bony projections at the back of each vertebra) of the lower spinal vertebrae. It inserts there, as well as at the skull’s base.
What does the spinalis dorsi do?
It is divided into three parts: Spinalis dorsi, spinalis cervicis, and spinalis capitis….

What are the names of the muscles in the semispinalis?
Anatomical terms of muscle. [edit on Wikidata] The semispinalis muscles are a group of three muscles belonging to the transversospinales. These are the semispinalis capitis, the semispinalis cervicis and the semispinalis thoracis.
Is the semispinalis in the back of the neck?
The semispinalis capitis (Latin: musculus semispinalis capitis) is a long thin muscle lying deep in the back of the neck, overlying the semispinalis cervicis. It is involved in head and neck movements.
What are the muscles of the transversospinales?
The semispinalis muscles are a group of three muscles belonging to the transversospinales. These are the semispinalis capitis, the semispinalis cervicis and the semispinalis thoracis.
Is the semispinalis thoracis part of the spinotransverse?
Sitting deep to semispinalis thoracis are the rotatores and levatores costarum, while superficially it is covered by the spinalis thoracis (erector spinae group). Just like all the spinotransverse muscles, semispinalis thoracis is innervated by the medial branches of the posterior rami of adjacent spinal nerves.
