The asymmetry due to divergence is observed from two norms, the facial and the occipital.
The asymmetry may be caused by one of the ears being placed too high up or too far back in respect to the other, or both asymmetries may occur together.
Asymmetry of form is perceived by observing successively the two external ears according to the lateral norms; their morphological aspect should correspond on the two sides.

We owe to Brugia a most admirable method for demonstrating the high degrees of facial asymmetry which sometimes reach such an extreme point as to give the two halves the appearance of having formed parts of two different faces.
One of the most frequent occurrences among the abnormal is asymmetry of the facial expressions; the muscles contract more on one side of the face than on the other.

Judging from what takes place in other mutations, it was quite possible for asymmetry to have developed directly from the egg, in consequence of some difference in the chromosomes of the nucleus.
A mutation consisting in general asymmetry would be comprehensible, but the head of the Pleuronectid is not asymmetrical in a general sense, but only so far as to allow of the changed position of the eyes.
There is no general and constitutional asymmetryof head or body, but a modification of different organs independently of each other in relation to external conditions-- light, food, movement.
The abnormal development is not due to a change occurring after the normal asymmetry has been developed.
This asymmetry affects particularly the premaxillae, the maxillae, and the nasals.
The asymmetry of the Whale's skull is one of its most remarkable features; this, however, is entirely limited to the Toothed Whales, and among them is more pronounced in some forms than in others.
Asymmetry of the folds is a marked characteristic in the zones of closer folding, the anticlines having long gently inclined easterly limbs, and short, steep and even overturned limbs upon the west.
Thus the pupils are unequal; there may be asymmetry of the face, or the limbs may be more rigid or flaccid on one side than on the other.
Even more important, Zen asymmetry forcefully draws one away from any mental connection one might have between completed form and notions of completion and timelessness in material things.

At such times asymmetry in the cell is apt to make some part of the plate take much more than its share of the current.
There is nothing in their mode of life which will afford an explanation of the asymmetry which is a developmental phenomenon.
Evidence from such cases is not so clear and simple as might be expected, because as a matter of fact, the heart and stomach, upon which the asymmetry of the viscera chiefly depend, are usually common to the two bodies.
The asymmetry was first observed when the child was three.
Congenital asymmetry and hemihypertrophy of the body are most peculiar anomalies and must not be confounded with acromegaly or myxedema, in both of which there is similar lack of symmetric development.
The bilateral asymmetry to which we have alluded produces the chess-board arrangement of the ventral spots in many snakes.
In all these cases the torsion and asymmetryof the body are unaffected.
He fully recognized, however, the similarity of Pteropods to Gastropods in their general asymmetry and in the torsion of the visceral mass in Limacinidae.
When the shell is sinistral the asymmetry of the organs is usually reversed, and there is a complete situs inversus viscerum, the direction of the spiral of the shell corresponding to the position of the organs of the body.
An outstanding example is Raphael's Sistine Madonna, where in the eyes and whole countenance both of Mother and Child this asymmetry can be studied in a specially impressive way.
The asymmetry of the crystal, due to a one-sided working of the forces of crystallization, plays the same role here as does the alchemic opposition between the two bodies used for the production of frictional electricity.
The asymmetry of the mouth is an independent trait, but, like the migration of the eye, is an adaptation to swimming on the side.
Each of the various traits of asymmetry may appear independently of the others.
Physical examination showed him to be a fairly well developed colored male, slight acneiform eruption over back, slight asymmetry of head, ears close set to head, lobules attached, palate high arched.
The asymmetry of face and cranium finds, as it were, its counterpart in their mental faculties.
There may be thermo-asymmetry often very marked, accompanied by but it is slight.
He was a tall, intelligent looking man with adherent lobules, slight facialasymmetry and evidence of tongue biting.
This asymmetry of the patella and Achilles reflexes lasted about 10 minutes after anesthesia was stopped, and lasted a little longer for the patella reflexes than for the Achilles reflexes.
There was a marked facial asymmetry and faulty arrangement of teeth.
The buccal facial asymmetry exists, it is commissure may be lowered, the due to spasm.
He was found to be mentally below par, nervous, apprehensive, stuttering in speech and not readily responsive, with defective vasomotor control, though of good average bodily development except for asymmetry of chest.
Although many of the adult forms are symmetrical, there is very early an asymmetry visible in the larva, shewing that the Pteropods are descended from asymmetrical ancestors.
In the Lobster, as in many of the higher Crustacea in which this asymmetry occurs, the larger claw may be indifferently on either side of the body.
Not solely to the old torticollis was the facial asymmetry attributable, but also to the convulsive movements of the right half of the face.
A complete cure ensued, but from that time a certain degree of facial asymmetry was remarked.
The peculiar asymmetry in the form of the rings raises the possibility that the two columellae in this species are the remaining parts of a frontal ring, and that the sagittal ring has altogether disappeared.
An irregularity or asymmetry of growth on the different sides of the shell is probably the cause of this strange, spiral structure.
The four pores of the collar septum (two larger cardinal and two smaller jugular) exhibit in this species a peculiar asymmetry (fig.
It habitually lies on one side in the mud of the sea bottom, and it is probable that this external asymmetry is due to this habit, so that too much classificatory importance must not be attached to it.
This origin of the coeliaco-mesenteric artery a little to the left, is the only asymmetry (want of balance) in the arterial system of the frog, as contrasted with the very extensive asymmetry of the great vessels near the heart of the rabbit.
Asymmetry is a common characteristic of the criminal physiognomy.
