In modern writing, there are simultaneous trends toward and away from capitalization. The trend in informal writing and much journalistic writing is away from it.

The deltoid muscle is a rounded, triangular muscle located on the uppermost part of the arm and the top of the shoulder.
The deltoid is innervated by the axillary nerve. The axillary nerve originates from the anterior rami of the cervical nerves C5 and C6, via the superior trunk, posterior division of the superior trunk, and the posterior cord of the brachial plexus. The anterior or clavicular fibers arises from most of the anterior border and upper surface of the lateral third of the clavicle. 2  The anterior origin lies adjacent to the lateral fibers of the pectoralis major muscle as do the end tendons of both muscles.
