Course and Termination
- Ends by curving laterally around the surgical neck of the humerus
Muscle Innervation
- The anterior branch of the axillary nerve provides a muscular branch to the deltoid muscle
Cutaneous Innervation
- The upper lateral cutaneous nerve of the arm provides cutaneous innervation to the skin overlying the lower part of the deltoid
