Muscle Atrophy Also known as: Muscle wasting, Wasting or Atrophy of the muscles. Definition. Muscle atrophy is the wasting or loss of muscle tissue. Causes. There are two types of muscle atrophy: disuse and neurogenic. Disuse atrophy is caused by not using the muscles enough. This type of atrophy can often be reversed with exercise and better nutrition.

Testicular atrophy Testicular atrophy. Testicular atrophy is a medical condition in which the male reproductive organs (the testes, which in humans are located in the scrotum) diminish in size and may be accompanied by loss of function. This does not refer to temporary changes, such as those brought on by cold.

Atrophy Atrophy is the general physiological process of reabsorption and breakdown of tissues, involving apoptosis. When it occurs as a result of disease or loss of trophic support due to other disease, it is termed pathological atrophy, although it can be a part of normal body development and homeostasis as well.

Medical Definition of Gastric atrophy Gastric atrophy: A condition in which the stomach muscles shrink and become weak. Gastric atrophy may result in a lack of digestive juices due to accompanying shrinkage of the digestive glands.astric atrophy: A condition in which the stomach muscles shrink and become weak.

The Dangers of an Eating Disorder: Muscle Atrophy Muscle atrophy is defined as a decrease in muscle mass. Muscular atrophy, the wasting or loss of muscle tissue, can result either from lack of use (disuse atrophy), from disease (neurogenic atrophy), or from malnutrition. Muscular atrophy caused by lack of use is reversible with appropriate exercise.

Background Optic atrophy is the final common morphologic endpoint of any disease process that causes axon degeneration in the retinogeniculate pathway. Clinically, optic atrophy manifests as changes in the color and the structure of the optic disc (cupping) associated with variable degrees of visual dysfunction. The term atrophy is actually a misnomer, since, in its strict histologic definition, means involution of a structure due to prolonged disuse.

- Vaginal atrophy is the medical term that refers to the thinning of the wall of the vagina that occurs during menopause (the time when menstrual periods have ceased) in women. Prior to menopause, the vaginal lining appears plump, bright red, and moist. Vaginal atrophy occurs due to falling estrogen levels. 2  Vaginal atrophy may be associated with vaginal dryness, itching, irritation, and/or pain during sexual intercourse.

- Muscle wasting is the loss of muscle tissue resulting in muscle weakness. Muscle wasting, also called muscle atrophy, is the weakening or loss of muscle tissue. Muscle wasting causes a significant decrease in muscle strength and the ability to move the muscle, according to MedlinePlus.

- Cerebral atrophy refers to the progressive loss of brain cells over time. Atrophy refers to a decreased size or wasting away of any part of the body. Cerebral atrophy can happen in either the entire brain or in just one part of the brain and can lead to decreased brain mass and loss of neurological function. The symptoms of cerebral atrophy depend on the cause and location of cell death.

Vaginal Atrophy (Atrophic Vaginitis) Vaginal atrophy is a change of the vagina that develops when there is a significant decrease in levels of the female hormone estrogen. The condition also is called atrophic vaginitis. Estrogen, which is produced by the ovaries, plays a vital role in keeping vaginal tissues lubricated and healthy. When levels of estrogen are low, vaginal tissue becomes atrophic — thin, dry and shrunken.

atrophy 1. decrease in size of a normally developed organ or tissue; wasting. 2. to undergo or cause atrophy. disuse atrophy. atrophy of local musculature due to failure to use a part of the body, due usually to pain. Is separate from neurogenic atrophy when nerve damage causes atrophy from both disuse and denervation.

Muscle Atrophy: Causes, Symptoms & Treatments Muscle atrophy is the loss or wasting of muscle tissue throughout the body. There are two basic ways in which this disease can form. The most severe form of this disease is neurogenic atrophy, a disease caused when an injury or disease harms the nerve which attaches to the muscle.This damage can occur quite suddenly.The second type of this disease is disuse atrophy which is caused by a lack of physical activity.When your muscles are not used often or movement is limited, your muscles can be damaged. This is a significant concern for those who are bedridden.his damage can occur quite suddenly. The second type of this disease is disuse atrophy which is caused by a lack of physical activity.

What Causes Leg Muscle Atrophy? Muscle atrophy is a loss of muscle tissue due to disuse, disease or injury. A decrease in physical activity can lead to muscle loss in as little as 72 hours. Atrophy can occur more suddenly with illness or injury to the muscles or their nerves, and the muscles in the legs are among the first to weaken.

atrophy Atrophy. Definition: Decrease in the size of cells, tissues, or organs. Causes of atrophy include poor nourishment, poor circulation, loss of hormonal support, loss of nerve supply to the target organ, disuse or lack of exercise, or disease intrinsic to the tissue itself.Hormonal and nerve inputs that maintain an organ or body part are referred to as trophic.Atrophy is a general physiological process of reabsorption and breakdown of tissues, involving apoptosis on a cellular level.

ATROPHY Cellular Adaptation — Atrophy. Atrophy is a form of cell adaptation in response to decreased trophic influences, decreased functional demands or decreased nutrition. Cellular Atrophy is a decrease in cell size caused by loss of subcellular organelles and substances.trophied cells have fewer and smaller organelles. Organ Atrophy is a decrease in the tissue mass of an organ due to either a decrease in size of individual cells (cellular atrophy), a decrease in number of cells, or both.

Muscle Atrophy Muscle atrophy takes place when a muscle partially or completely wastes away and its mass decreases. Most cases of muscle atrophy are usually results of other pre-existing medical conditions that include the loss of muscle mass as a side effect. Loss of muscle mass can be characterized by fatigue, extreme muscle weakness, or the actual shrinking of the physical body of the affected individual.
