3 Νοε 2023 · Being a part of transversospinal muscle group along with semispinalis and multifidus, rotatores comprise the deep layer of deep, or intrinsic, muscles of the back. They can be divided regionally into rotatores colli/cervicis, rotatores thoracis and rotatores lumborum.
23 Νοε 2023 · The semispinalis muscle is one of the transversospinales muscles, which are a group of deep muscles within the back which lie deep to the erector spinae. There are three major muscle groups within the transversospinales: semispinalis, multifidus and rotares.
3 Νοε 2023 · As part of the transversospinal muscle group, multifidus is located in the third or deep layer of deep muscles of the back. It lies deep to erector spinae, semispinalis cervicis and thoracis, while it is located superficial to rotatores muscles.
Together with the multifidus and rotatores, the semispinalis muccle lies in the deep layer of the deep back muscles. It is located on either side of the spine and extends from the skull to the tenth thoracic vertebrae. The semispinalis muscles are subdivided into three portions based on their location.

15 Οκτ 2024 · Anatomical variations exist, where, in some areas, the rotatores are replaced by deeper muscle fibers of the multifidus. The rotatores muscles make up the deepest layer of the transversospinales group, with the multifidus muscles lying immediately superior to it.
