Learn the brachioradialis muscle’s attachments, open- and closed-chain functions, palpation technique, and why it’s the ultimate example of a muscle that changes its joint action with joint position.
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.
Epimuscular Myofascial Force Transmission in Upper Limbs
Epimuscular myofascial force transmission is a concept that concerns transmission of muscular forces other than the sliding filament mechanism.
