Semispinalis Thoracis Semispinalis Thoracis connects T7-T10 to C6-T4 trapping T5-T6 in the middle. Origin – transverse processes of T6-T10 Insertion – Spinous processes of T1-T4 Function – Extension and some rotation of the thoracic vertebrae. Wikipedia Entry for Semispinalis muscles
Overview Semispinalis cervicis fits between the deeper multifidi and the more superficial erectors and serratus anterior. It is a thin muscle that connects the transverse processes of the upper thoracic vertebrae with the mid-cervical vertebrae. Consequently, It is in a position to trap and compress the lower cervical vertebrae. Interestingly, the posterior rami of those
Multifidi and Rotatores The anatomy studies and illustrations of the multifidus and rotatores vary a great deal. In general, They anchor near the base of the transverse process of a vertebra. Then, strands of muscle extend to spinous processes of the five vertebrae above them. There are exceptions to that generalization. Overall Structure Multifidi and
