088 The Deep Extrinsic Shoulder Muscles

In this video, Leslie Samuel discusses the deep extrinsic shoulder muscles, focusing on the levator scapulae, rhomboideus minor, and rhomboideus major. The video explains the origins, insertions, and actions of these muscles, using a mnemonic system to aid memory. The levator scapulae originates from the transverse processes of C1-C4 and elevates the scapula. The rhomboideus minor originates from the spinous processes of C7 and T1, causing scapula retraction. The rhomboideus major originates from T2-T5, also causing retraction and rotation. The video concludes with a review and encourages viewers to visit interactive-biology.com for more resources.
