muscles
100
Skeletal, striated, and voluntary describe what
What is the three types of muscle tissue?
100
This is the muscle's attachment to the more stationary bone
What is its origin
100
These are the threadlike microfilaments
What is thick and thin myofilaments
100
This is the muscle that is mainly responsible for producing a particular movement
What is the prime mover
100
This is the condition when muscles shrink in size, due to lack of use
What is disuse atrophy
200
These are smooth and cardiac muscle
What are two additional types of muscle?
200
This is the muscle's attachment to the more moveable bone
What is its insertion
200
This is the protien that the thick myofilaments are composed of
What is myosin
200
This is the secondary or "other" muscle that helps in producing movement
What is the synergist muscle
200
This condition describes when muscles increase in size from use or exercise
What is hypertrophy
300
These muscle fibers are tapered at each end and have a single nucleus
What is smooth muscle
300
This anchors muscles firmly to bones
What is tendons
300
This is the protein that the thin myofilaments are composed of
What is actin
300
This is the muscle that relaxes as the prime mover and synergist muscle contract
What is the antagonist
300
During this process muscles are enhanced from contracting against heavy resistance
What is strength training
400
These muscle fibers lack cross stripes or striations
What are nonstriated muscle fibers
400
Theses are the small fluid filled sacs betweensome tendons and bones
What are bursae
400
This is the basic function or contractile unit of the muscle
What is sarcomere
400
This is what maintains body position, through low strength muscle contractions
What is muscle tone or tonic contraction
400
This type of exercise program increases a muscle's ability to sustain moderate exercise over a long period of time
What is endurance training or aerobic training
500
These are muscles, in which the contractions are not controlled
What is an involuntary muscle
500
This is the lining of the bursae, or connective tissue sacs
What is synovial membrane
500
This model explains the contractions of muscle fibers
What is the sliding filament model
500
This is the nerve fiber that stimulates the muscle fiber
What is a motor neuron
500
This produces muscle movment at a joint
What is an isotonic contraction
