This article will discuss the anatomy and function of the semispinalis cervicis muscle.
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.
The semispinalis capitis extends from the superior nuchal line of the occiput to the transverse processes of T1–T6. It covers the spinalis cer - vicis. The semispinalis thoracis is stretched from spinous processes of C2 to T4 to transverse processes from T2 to T11. It is covered at the top by the semispinalis capitis and at
