2023年11月3日 · Semispinalis thoracis consists of five fascicles bridging over five to six vertebral levels between the transverse and spinous processes of certain cervical and thoracic vertebrae. With these attachments, semispinalis thoracis aids several movements of the vertebral column; specifically extension, lateral flexion and rotation of the

The semispinalis thoracis (or semispinalis dorsi) muscle consists of thin, narrow, fleshy fasciculi, interposed between tendons of considerable length. It arises by a series of small tendons from the transverse processes of the sixth to the tenth thoracic vertebrae , and is inserted, by tendons, into the spinous processes of the upper four ...

Explore the semispinalis thoracis muscle's origin, insertion, action, innervation and arterial supply for better understanding of human anatomy.

2024年10月22日 · The semispinalis thoracis is a narrow muscle located in the upper to mid-back region. It is the lowest of the three semispinalis muscles, belonging to the transversospinalis or deep intrinsic back muscle group. Along with the other semispinalis muscles, it helps with the extension and rotation of the head and neck.

2025年2月7日 · The semispinalis thoracis muscle plays a crucial role in spinal mobility and stability, forming an integral component of the deep muscles of the back. This comprehensive analysis explores its anatomical relationships, functional significance, and clinical implications that every medical professional should understand.

2020年7月29日 · The Semispinalis thoracis muscle consists of narrow, thin, fleshy fascicule that is interposed between the surrounding tendons of considerable length. It erupts from a series of small tendons out of the transverse processes for the sixth to the tenth thoracic vertebrae.

Semispinalis thoracis muscle - thin, fleshy fascicles with long tendons at either end. Covers the thoracic multifidus muscle and is regarded as the inferior portion. origin: T6-T10 transverse processes

The semispinalis cervicis (Latin: musculus semispinalis cervicis), also known as the semispinalis colli, is the middle portion of the semispinalis muscles. It lies over the cervical and thoracic parts of the multifidus. The semispinalis thoracis (Latin: musculus semispinalis thoracis) is the lower portion that overlies the thoracic multifidus.

2023年9月10日 · Trigger points of the semispinalis cervicis and the semispinalis thoracis form a similar pain pattern. The presence of trigger points in all parts of the semispinalis muscle results in limited neck flexion, rotation and lateral tilt.

2020年7月29日 · The Semispinalis thoracis muscle consists of narrow, thin, fleshy fascicule that is interposed between the surrounding tendons of considerable length. It erupts from a series of small tendons out of the transverse processes for the sixth to the tenth thoracic vertebrae.
