089 What are the Six Intrinsic Shoulder Muscles?

Leslie Samuel introduces a video on intrinsic shoulder muscles, focusing on those originating from the scapula and inserting on the humerus. The video lists six muscles: deltoid, supraspinatus, infraspinatus, teres minor, teres major, and subscapularis. Details on origins, insertions, and actions are reserved for a future video. The video concludes with a call to visit interactive-biology.com for more resources.
