Oh, are you struggling with learning anatomy? We created the ★ Ultimate Anatomy Study Guide ★ to help you kick some gluteus maximus in any topic. Completely free.

The deltoid muscle is one of the most prominent muscles of the shoulder and arm. It is innervated by the axillary nerve from the brachial plexus and plays an important role in various movements in the shoulder joint.

Its three parts (clavicular, acromial and spinal) originate from their respective bones and they all insert at the deltoid tuberosity at the lateral shaft of the humerus.

In this video tutorial are going to talk about the most important anatomy facts about the deltoid muscle, including origin, insertion, innervation and functions of the different parts of this muscle:

- origin and insertion of the clavicular part
- origin and insertion of the acromial part
- origin and insertion of the spinal part
- innervation by the axillary nerve
- functions of the three parts of the deltoid muscle

Very good job. Deltoid is a word from greek language. Delta δέλτα is the forth letter of alphabet

I have a question guys. I'm confused cuz lately I've seen literature talking about 7 anatomical segments on the deltoid. So does this mean 7 actual parts or heads on the deltoids? Please I'd love to hear an answer so I can get concepts clear on my head @Kenhub

But the axillary nerve can't be repaired right?
