Their conjoint function facilitates the movements of the vertebral column; extension, lateral flexion and rotation of the head, cervical and thoracic spines. This article will discuss the anatomy and function of the semispinalis cervicis muscle.
spinae can be subdivided into the following parts: 1. Medial Part a) transversopinalis In the thoracic part, the muscle extends cranially and medially as semispinalis thoracis. Further cranially, now as semispinalis cervicis, the muscle inserts on the spinous process of C2.
3 Νοε 2023 · With these attachments, semispinalis thoracis aids several movements of the vertebral column; specifically extension, lateral flexion and rotation of the thoracic spine. Acting together with semispinalis capitis and cervicis, it supports the same movements occuring at the head and neck.
