Muscular atrophy means that muscle that was there has degenerated. It can happen because of disuse (like if you have a broken bone that's in a cast for a period of time) or because innervation to that muscle has been interrupted (as with a spinal cord injury), or any other reason that it isn't being used.
Hypertrophy is increase in the size or number of muscle cells (myocytes). You might say that a bodybuilder or someone with overdeveloped muscles in their arms from using a wheelchair demonstrates hypertrophy, but in a pathological sense, you can also see hypertrophy in muscles in children with muscular dystrophy (getting to that). That happens because of repeated damage to the muscle cells; as long as the body can, it will try to compensate by increasing the size of the remaining cells.
Dystrophy means any condition associated with abnormal development. It can be due to malnutrition or to genetic disorders like Duchenne or Becker's muscular dystrophy.
Hyper- and hypotonia are, respectively, increase and decrease in overall muscle tone. You can think of them as spasticity or inability to stretch or a tendency to contract and "floppiness" or looseness of muscle tissue or decreased resistance to movement, respectively. They can be due to any number of different disorders; they are very general terms.
Hypertrophy is the increase in size of an organ or tissue due to the enlargement of cells, while atrophy is the decrease in size of an organ or tissue due to a decrease in cell size or number. Hypertrophy is typically seen in response to increased workload or exercise, while atrophy can be caused by disuse, injury, or certain diseases.

What is a term that refers to a decrease in cell size?
Atrophy- refers to a decrease in cell size.
What is the difference between hypertrophy and hyperlasia?
Hypertrophy refers to the enlargement of existing cells, resulting in an increase in the size of an organ or tissue. Hyperplasia, on the other hand, involves an increase in cell number through cell division, leading to the growth of the organ or tissue. Essentially, hypertrophy involves cells growing bigger, while hyperplasia involves more cells being produced.
What is the difference between hyperplasia and hypertrophy?
Hyperplasia is an increase in the number of cells in an organ or tissue, leading to its enlargement, whereas hypertrophy is an increase in the size of existing cells in an organ or tissue. Both processes contribute to the growth of tissues, but through different mechanisms.
Is a general increase in the bulk of a body part due to an increase in the size but not in the number of cells?
Hypertrophy
An increase in the size of a cell is called?
Hypertrophy. It refers to the increase in the size of individual cells, leading to overall growth of the tissue or organ. Hypertrophy can occur in various tissues, such as muscle tissue in response to exercise.
What is the opposite of Atrophy?
Hypertrophy - adapting
Does atrophy of muscles cause a increase in size?
atrophy is a decrease in muscle mass. Hypertrophy is muscle growth.
Whats the difference between muscle mass and muscle hypertrophy?
The difference between muscle mass and muscle hypertrophy is that muscle hypertrophy is the increase in size of skeletal muscle while muscle mass is the weight of your body muscle.
What is a term that refers to a decrease in cell size?
Atrophy- refers to a decrease in cell size.
What is the definition of Muscles that are forced to work harder generally increase in size?
The technical term for this is hypertrophy. It is the opposite of atrophy.
What is the difference between hypertrophy and hyperlasia?
Hypertrophy refers to the enlargement of existing cells, resulting in an increase in the size of an organ or tissue. Hyperplasia, on the other hand, involves an increase in cell number through cell division, leading to the growth of the organ or tissue. Essentially, hypertrophy involves cells growing bigger, while hyperplasia involves more cells being produced.
What is the difference between Left Ventricular Hypertrophy and Left Ventricular Dysfunction?
LVH (Left Ventricular Hypertrophy) is (anatomical) structural condition and status of the heart, while Left Ventricular Dysfunction is disturbance in physiological functions and status of heart.
What does the medical terminology combining form trophy- mean?
In medical terms, trophy is a tendency. It comes in two forms. Atrophy is a reduction or disappearance of some structure, and hypertrophy is the increase or growth of some structure.
How can the shape of muscle cell change?
Muscle cells can change shape through processes such as hypertrophy (increase in size) or atrophy (decrease in size). Hypertrophy occurs when the muscle cell grows in response to increased workload, such as through exercise. Atrophy, on the other hand, can be caused by disuse, injury, or disease which results in a reduction in the size of the muscle cell.
What is the difference between muscle dystrophy and muscle atrophy?
Myasthenia gravis: autoimmune to the ACh receptors at end plate (pathway >>> no muscle contraction) Muscular Dystrophy: genetic (X-linked) defect in dystrophin (pathway >>> myosin-actin crossbridge doesn't form > no muscle contraction)
What is the difference between hyperplasia and hypertrophy?
Hyperplasia is an increase in the number of cells in an organ or tissue, leading to its enlargement, whereas hypertrophy is an increase in the size of existing cells in an organ or tissue. Both processes contribute to the growth of tissues, but through different mechanisms.
How do muscles get larger or smaller?
by hypertrophy (bigger) by making them do alot more work than they use to by lifting weights usually, and atrophy (not being used to same extent as they were)for them to get smaller or 'waste' away from lack of a sustained workload.
