Deltoid Muscle and Axillary Nerve

The video tutorial uses a Simon Says game to introduce the deltoid muscle, explaining its anatomy, parts, and functions. It covers the clavicular, acromial, and spinal parts of the deltoid, detailing their roles in shoulder movements. The tutorial also discusses axillary nerve injury, its causes, symptoms, and management options. The video concludes with a call to explore more resources on Kenhub for further learning.
