Anatomically, the deltoid muscle is made up of three distinct sets of muscle fibers, namely the anterior or clavicular part (pars clavicularis) posterior or scapular part (pars scapularis) intermediate or acromial part (pars acromialis) The deltoid's fibres are Pennate muscle.

2019年8月22日 · The deltoid muscle (also known as deltoideus muscle) is the largest of the shoulder muscles. The muscle is composed of three heads (clavicular, acromial and spinous), although electromyography suggests that there are at least seven control regions that could act independently 1.
