They posses inhibitory zones at one or both ends of oriented excitatory regions, thereby responding to bars of preferred orientation only if they are not too long.

Hyperglycemia
Too high a level of glucose (sugar) in the blood; a sign that diabetes is out of control. Many things can cause hyperglycemia. It occurs when the body does not have enough insulin or cannot use the insulin it does have to turn glucose into energy. Signs of hyperglycemia are a great thirst, a dry mouth, and a need to urinate often. For people with Type 1 diabetes, hyperglycemia may lead to diabetic ketoacidosis.
Hyperglycemic
High blood sugar.

See Nonketotic Coma.
Hyperinsulinemia
The excess production of insulin. This is usually a consequence of insulin resistance in which the cells do not respond to insulin to reduce blood glucose levels.
Hyperinsulinism
Too high a level of insulin in the blood. This term most often refers to a condition in which the body produces too much insulin. Researchers believe that this condition may play a role in the development of noninsulin-dependent diabetes and in hypertension.
Hyperlipidemia

Hypermobility syndrome
Syndrome of arthralgia associated with joint hypermobility.
Hyperopia
Hyperopia (or more rarely, hypermetropia), also known as farsightedness or longsightedness, is a defect of vision caused by an imperfection in the eye (often when the eyeball is too short), causing inability to focus on near objects, and in extreme cases causing a sufferer to be unable to focus on objects at any distance. As an object moves towards the eye, the eye must increase its power to keep the image on the retina.
Hyperorgasmia
The phenomenon of having an inordinate number of orgasms within a given period, as compared with a given criterion standard.
Hyperparathyroidism
Excessive secretion of parathyroid hormone from the parathyroid glands, which are situated alongside the thyroid gland in the throat, and which play a role in regulating the amount of calcium in blood and body tissues.
Hyperphilia
A condition or syndrome, variable in etiology and diagnosis, of being sexuoerotically above standard or inordinate, particularly with respect to some aspect of genital functioning prior to and at the acceptive phase. The condition of being supranormal in sexual and genital responsiveness or frequency.
Hyperphoria
A tendency for one eye to drift upward. A vertical type of muscle imbalance between the eyes.
Hyperpigmentation
Post-inflammatory hyperpigmentation is an excessive skin darkening at places where the skin was inflamed.
Hyperplasia
An increase in the number of cells in a tissue or organ, usually as a physiologic response to a stimulus.
Hypersensitivity
State of reactivity to antigen that is greater than normal for the antigenic challenge; hypersensitivity is the same as allergy and denotes a deleterious outcome rather than a protective one.
Hypersomnia
Excessive difficulty maintaining an alert awake state during the day, or undesired daytime sleep episodes. sleepiness, as evidenced by prolonged nocturnal sleep, ideas of reference The feeling that casual incidents and external events have a particular and unusual meaning that is specific to the person. This is to be distinguished from a delusion of reference, in which there is a belief that is held with delusional conviction

Hyperstat
Hyperstat is a prescription or over-the-counter drug which is (or once was) approved in the United States and possibly in other countries. Active ingredient(s): diazoxide.
Hypertension
Higher blood pressure than normal. Diastolic blood pressure from 90 to 99 mm HG is considered mild hypertension; 100–109, moderate hypertension; and 110 or greater, severe hypertension. Systolic blood pressure from 140 to 159 mm HG is considered mild hypertension; 160–179, moderate hypertension; and 180 or greater, severe hypertension.
Hypertension (high blood pressure)
An arterial condition whose primary feature is chronically elevated blood pressure.
Hyperthermia

Rapid or deep breathing producing faintness, numbness, chest pain, apprehension and tingling, and spasms of the extremities.
PREVIOUS AND NEXT TERMS--------------------------------------
Hybristophilia
A paraphilia of the marauding/predatory type in which sexuoerotic arousal and facilitation and attainment of orgasm are responsive to and [dependent upon] {contingent on} being with a partner known to have committed an outrage or crime, such as rape, murder, or armed robbery [from Greek, hybridzein, to commit an outrage against someone + -philia]. The partner may have served a prison sentence as a convicted criminal, or may be instigated by the hybristophile to commit a crime and so be convicted and sent to prison.
Hyperorgasmia
The phenomenon of having an inordinate number of orgasms within a given period, as compared with a given criterion standard.
Hyperparathyroidism
Excessive secretion of parathyroid hormone from the parathyroid glands, which are situated alongside the thyroid gland in the throat, and which play a role in regulating the amount of calcium in blood and body tissues.
Hyperphilia

The condition of being supranormal in sexual and genital responsiveness or frequency.
Hyphephilia
One of a group of paraphilias of the fetishistic/talismanic type in which the sexuoerotic stimulus is associated with the touching, rubbing, or the feel of skin, hair, leather, fur, and fabric, especially if worn in proximity to erotically significant parts of the body [from Greek, hyphe, web + -philia].
Hypertrophy
Hypophilia
A condition or syndrome, variable in etiology and diagnosis, of being sexuoerotically substandard or deficient, particularly with respect to some aspect of genital functioning at the acceptive phase; impaired or deficient in sexual and genital responsiveness or frequency. The condition of being subnormal in sexual and genital responsiveness or frequency.
Hypopituitarism
A generalized endocrine deficiency condition produced by failure, either partial or complete, of the pituitary gland to secrete its proper hormones. Failure after surgery for a pituitary tumor is usually complete. Idiopathic failure may be either complete or partial. In some instances, partial failure may involve chiefly the secretion of pituitary gonadotropins, the hormones that stimulate the ovaries or the testes to produce their own hormones.
Hypospadias
A birth defect in the positioning of the urethral (urinary meatus) opening on the penis in males or into the vagina in females. In mild male hypospadias, the opening is only slightly displaced from the tip of the penis. In severe male hypospadias, the opening is in the female position, at the base of the scrotum, and the penis has an open gutter on its underside, instead of a covered urinary canal. A hypospadiac penis may be normal sized or small. 2. A birth defect in the male in which the urinary opening is on the underside of the shaft of the penis anywhere from the glans (first degree) to the perineum (third degree or penoscrotal hypospadias). A small penis with a severe degree of hypospadias is identical in appearance with an enlarged clitoris below which is a single opening or urogenital sinus leading to both the urethra and the vagina. Artificial hypospadias may occur as a sequel to an injury, as in a circumcision accident, or be self-inflicted.
Hyperspadias
A congenital malformation or misplacement of the urethra as in hypospadias except that the position of the opening is on the upper or superior/dorsal surface of the penis.
Hypothyroidism
Deficiency of thyroid hormone; the opposite of hyperthyroidism. The thyroid gland is in the throat, near the larynx or Adam's apple.
