Muscle System Flashcards
(25 cards)
tendon
fascia that has extended past its associated muscle to connect to bone
fascia
muscle covering made of fibrous connective tissue
ligament
fascia that connects bones to bones
epimysium
fascia that surrounds an entire muscle
muscle fibers, aka
muscle cells, aka
fascicles
bundles of muscle fibers
composition of fascia
irregular connective tissue
perimysium
fascia that surrounds fascicles
endomysium
fascia that separates muscle fibers
composition of endomysium
fascia made of mostly reticular fibres
composition of epimysium
fascia layer made of dense irregular connective tissue
composition of perimysium
fascia layer made of dense irregular connective tissue
aponeurosis
sinewy, broad, flat sheet extension of fascia
myofibers, aka
muscle fibers, aka
sarcolemma
plasma membrane of a muscle cell
sarcoplasm
cytoplasm of a muscle cell
composition of myofibrils
formed of many sarcomeres, end to end, within muscle cells
immature muscle cells that fuse to create a muscle fiber
myoblasts
function of myofibrils
contractile organelles of muscle fiber
2 types of myofilaments
thin & thick filaments
made of many myofilaments
structure of sarcomeres
two functions of sarcoplasmic reticulum
surrounds each myofibril and stores calcium
equivalent organelle to sarcoplasmic reticulum in other cells
equivalent organelle to endoplasmic reticulum in muscle cells
composition of thin myofilaments
myofilament composed of actin proteins
