What is trapezius pars Descendens?

What is the insertion of the trapezius Part 1?
Trapezius Attachments It originates on the occipital bone, the ligamentum nuchae, and the spinous processes of T01–T12. The trapezius inserts on the lateral third of the clavicle, as well as the acromion and scapular spine of the scapula.
What nerve Innervates the upper trapezius?
Cranial nerve XI innervates the motor function of the trapezius. The function of the trapezius is to stabilize and move the scapula. The upper fibers can elevate and upwardly rotate the scapula and extend the neck.

What nerve supplies the sternocleidomastoid?
The sternocleidomastoid muscle is generally considered to have nerve supply from the accessory nerve. However, the innervation pattern to the SCM is not so simple and it also receives fibers from the C2 and C3 anterior branches, as studied by Caliot et al.
