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.

What is the difference between hypertrophy and hyperlasia?
The difference between hypertrophy and hyperplasia is size. With hypertrophy there is an increase in the size of a body organ. In hyperplasia there is an increase in the number of cells in an organ.
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 hyperplasia and hypertrophy?
Hyperplasia is the enlargement of tissues or an organ due to an increase in the number of cells, while hypertrophy causes the same result, but is due to an increase in the size of cells.
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
What is bone atrophy?
Atrophy is the wearing away of an organ or tissue because of lack of use. Bone Atrophy, obviously, is atrophy of bones.
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 hyperplasia and hypertrophy?
Hyperplasia is the enlargement of tissues or an organ due to an increase in the number of cells, while hypertrophy causes the same result, but is due to an increase in the size of cells.
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.
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)
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
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.
