Thymus atrophy during early human development (childhood) is an example of physiologic atrophy. Skeletal muscle atrophy is a common pathologic adaptation to skeletal muscle disuse (commonly called "disuse atrophy"). Tissue and organs especially susceptible to atrophy include skeletal muscle, cardiac muscle, secondary sex organs, and the brain ...
Atrophy is the partial or complete wasting away of a part of the body. Causes of atrophy include mutations (which can destroy the gene to build up the organ), poor nourishment, poor circulation, loss of hormonal support, loss of nerve supply to the target organ, excessive amount of apoptosis of cells, and disuse or lack of exercise or disease intrinsic to the tissue itself.
Hypertrophy is the increase in the volume of an organ or tissue due to the enlargement of its component cells. [1] It is distinguished from hyperplasia , in which the cells remain approximately the same size but increase in number. [ 2 ]
Atrophy (reduced functionality of an organ, with decrease in the number or volume of cells) Hypertrophy (increase in the volume of cells or tissues) Hypotrophy (decrease in the volume of cells or tissues) Dystrophy (any degenerative disorder resulting from improper or faulty nutrition)
The muscle hypertrophy may persist throughout the course of the disease, or may later atrophy, or become pseudohypertrophic (muscle atrophy with infiltration of fat or other tissue). For instance, Duchenne and Becker muscular dystrophy may start as true muscle hypertrophy, but later develop into pseudohypertrophy. [41]
Cerebral atrophy is a common feature of many of the diseases that affect the brain. [1] Atrophy of any tissue means a decrement in the size of the cell, which can be due to progressive loss of cytoplasmic proteins. In brain tissue, atrophy describes a loss of neurons and the connections between them.
Pseudohypertrophy, or false enlargement, is an increase in the size of an organ due to infiltration of a tissue not normally found in that organ. [1] It is commonly applied to enlargement of a muscle due to infiltration of fat or connective tissue, [2] famously in Duchenne muscular dystrophy.
Muscle atrophy from intristic disease in an 18-year-old woman, weight 27 pounds (12.2 kg) Muscle atrophy from intristic disease in a 17-year-old girl with chronic rheumatism Muscle diseases, such as muscular dystrophy , amyotrophic lateral sclerosis (ALS), or myositis such as inclusion body myositis can cause muscle atrophy.
