Key points

  • The deltoid forms the rounded contour of the shoulder and covers the shoulder joint.
  • Its anterior, middle and posterior parts arise from the clavicle and scapula and attach to the humerus.
  • The middle part mainly raises the arm sideways, while the anterior and posterior parts contribute to forward and backward movement.
  • The axillary nerve supplies the deltoid, with fibres mainly from the C5 and C6 spinal nerve roots.
  • The right deltoid muscle is the right-sided structure used to anchor this article in the 3D model.
