Muscle Tone

Muscle tone

Maintained due to partial contraction of relaxed portions of skeletal muscle. There are ALWAYS a few muscle fibers within a muscle that are contracted while most are relaxed. This is ESSENTIAL in maintaining posture.

Hypotonia

Decreased or lost muscle tone. Muscles are "flaccid".

Atrophy

Wasting away of muscles due to disuse or severing the nerve supply.

Hypertrophy

Increase in the diameter of muscle fibers from forceful repetitive muscular activity such a weightlifting.
