Semispinalis Capitis – Functional Anatomy

Semispinalis Capitis Semispinalis Capitis connects the C4-T7 to the occipital bone trapping C1-C3. Dissection studies vary in their report of attachments on the thoracic vertebrae. They show that they not only vary in which vertebrae are attached butContinue reading

Semispinalis Thoracis – Functional Anatomy

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.     Continue reading

Semispinalis Cervicis – Functional Anatomy

Semispinalis Cervicis Semispinalis Cervicis connects the transverse processes of  T1-T6 to the spinous processes of C2-C5 trapping C6-C7. Origin – transverse processes of T1-T5 or T6 Insertion – Spinous processes of C2-C5 Function – Extension and someContinue reading

Rotatores and Multifidi – Functional Anatomy

Multifidi and Rotatores Multifidi and rotatores form a thick band of muscle that fills the lamina groove. They connect the transverse process of a vertebra to the vertebrae above it. The shortest strand is the deepest. As theContinue reading
