Introduction to the Cervical Spine
It is extremely important to be able to locate and palpate the laminar groove of the cervical spine because the thickest musculature is located there.
Coracobrachialis: Attachments, Functions, Palpation & Treatment
The coracobrachialis is a muscle in the anterior compartment of the upper arm. It originates on the coracoid process of the scapula and inserts on the medial shaft of the humerus. It performs flexion and adduction at the glenohumeral joint and serves as a key teaching muscle for core kinesiology concepts including open-chain vs. closed-chain movement, cardinal-plane vs. oblique-plane motion, and anatomic vs. non-anatomic actions.
