The Human Skull Drawings Muscles

The ear is shell-shaped in form and general structure. Its outer contour is formed like a C, wider at the top and narrower at the base. In the center, it has a bowl-like depression, the concha, large enough to admit the curve of the thumb. ►

forms of ear

The ear has four major forms: the wide, outer encircling rim (helix) ; the smaller inside rim (antihelix), which encloses the depressed bowl; the lower fleshy base (lobule); the firm projection (tragus) which overhangs the opening to the ear canal. The inner rim (anti-helix), divides at the top into two arms, forming a bent Y shape. Below the tragus is a small notch, just under and outside the ear canal opening. The tubercle, a small knot on the upper outside curve of the helix, is sometimes called Darwin's point. The curve of the helix turns into the bowl of the ear and implants itself in the central wall. ▼

PROPORTIONS OF EAR

WIDTH COMPARED TO LENGTH

The entire ear lies within two lines drawn from the top of the eyebrow and the base of the nose. The ear divides vertically into three generally equal parts.

First part: from the top of the ear to the point where the helix attaches to the side of the head.

Second part: the mid-region of the ear is occupied entirely by the bowl (concha). The tragus is at the exact midpoint of the ear.

Third part: the lobe of the ear. The bottom of the lobe aligns with the base of the nose.

The width of the ear is half the length. This measure occurs only at the highest part of the ear, the helix or outer rim.

PLACEMENT OF EAR

On the side plane of the head, the ear tips slightly backward at an angle of 15 degrees. Seen from the back, the outer rim of the ear stands away from the head at an angle of almost 20 degrees. This view clearly reveals the rounded back wall of the central bowl.
