muscles test 2 Flashcards
what is muscle tissue?
tissue that generates movemet
what are the types of muscle tissue?
skeletal muscle
cardiac muscle
smooth muscle
which type of muscle tissue is:
- attached to bones
- has stripes(striated muscle) for strong contractions
- not individual cells
- multiple cells fused together into a long rod called a muscle fiber.
- strongest muscle tissue
- fibers are multi nucleate
skeletal muscle tissue
which type of muscle tissue is:
- found in the heart
- striated muscle for strong contractions
- not fibers
- single cells with branched ends
- have intercalated discs between cells
- not voluntary has automaticity (can contract with no input from nervous system)
cardiac muscle tissue
which type of muscle tissue is:
- in hollow organs, digestive organs, and blood vessels
- No striations
- single cells
- weakest muscle
- not voluntary
- one nucleus
- not fibers
smooth muscle tissue
what is the anatomy of muscle tissue?
connective tissue holds cells together in muscle tissue
what is the term for connective tissue holding a muscle together?
Fascia
what is dense irregular connective tissue wrapping entire muscle, extends past the muscle as a tendon and fuses with the periosteum of bone?
Epimysium (layer of fascia)
which layer of fascia wraps bundles of muscle fibers into fascicles?
Perimysium
which layer of fascia is connective tissue wrapping each individual muscle fiber?
Endomysium
what is the origin?
attachment to bone or bones that does NOT move
what is the insertion?
attachment to bone or bones that DOES move.
what is the “belly”?
the mass of muscle
what is parallel(direction of fibers)?
fibers run in parallel lines along the length of the muscle
what is fusiform?
like parallel except muscle has a wide belly so fibers curve
