Fibromyalgia
progressive wasting and weakening of the muscles
Chronic pain in specific muscle sites. Cause is unknown. Treatment is directed toward pain relief
Paralysis of muscle
which is not a characteristics of muscles
Excitability
Contractibility
elasticity
protect
Excitability
ability to respond to a stimulus such as a nerve impulse
muscle fibers that are stimulated by nerves contract, or become shorter, which causes movement
the ability to be stretched
allows the muscles to return to its original shape after it has contracted or stretched
smooth muscle
tendon
cardiac muscle
skeletal muscle
extensibility
the ability to be stretched
ability to respond to a stimulus such as a nerve impulse
allows the muscles to return to its original shape after it has contracted or stretched
Strain
overstretching of or injury to a muscle or tendon
sudden painful, involuntary muscle contractions
progressive wasting and weakening of the muscles
Muscle functions include Movement, Support. Protect and
thermogenesis
elasticity
Contractibility
antagonistic pairs
