Thus in my opinion the question is decided ; the kidney is but an organ of elimination; its office in diabetes is to eliminate the sugar from the blood, as it is in health to eliminate the urea.

deltoidus

Like deltoid, ultimately from Ancient Greek δέλτα (délta), the triangular fourth letter of the Greek alphabet, and the suffix -(ο)ειδής (-(o)eidḗs, “-like”), the source of English -oid. This suffix has usually been adapted in Neo-Latin as -oīdēs or -oīdeus (giving Latin deltoīdēs or deltoīdeus), but the variant or misspelling -oīdus is attested in some Latin texts. As an English word, the form deltoidus might have been taken from such Latin variants, or may have been created analogically within English by simply combining deltoid with the ending -us (seen in some other muscle names such as trapezius).

The deltoid muscle of the human raises the arm. Its anterior section pulls the arm forward and rotates it inward while its posterior section pulls it backward and rotates it outward. The same muscle in the animal, known as the deltoidus, abducts the upper portion of the forelimb and flexes the shoulder.

1983, Fredric Sweney, The Art of Painting and Drawing Animals, page 37:

The deltoidus is a thick, large triangular muscle that covers the shoulder joint in the front, behind and laterally. It encircles the cap of the shoulder. The muscle fibers converge to unite in a thick tendon which inserts into the middle lateral side of the upper arm bone. The muscle's basic action is to lift the arm away from the body. It makes sense then that forward, lateral, and backward movements are necessary to work the muscle fully. ¶ The trapezius is a flat triangular muscle that covers parts of the neck, shoulders and upper back.

2012, Arnold Schwarzenegger, Douglas Kent Hall, Arnold: The Education of a Bodybuilder:

The muscles involved in the external rotation are: Infraspinatus, Teres minor, Deltoidus and Supraspinatus.

Within the greasy T-zone is an area referred to as the ‘danger triangle’. The client may be tempted to squeeze spots that appear there. This should be warned against very strongly. Behind this area are important blood vessels which connect with the brain. Fatalities have resulted from deep-seated bacterial infections behind the danger triangle, caused by skin damage.
