perimysium
endomysium
what is the perimysium? - answerCT that wraps around a fascicle
what is the epimysium? - answersurrounds entire muscle; largest layer
what is a fasicle? - answerbundle of muscle fibers
what is the endomysium? - answerwraps around individual muscle fibers
list the structure of skeletal muscle from largest to smallest - answerepimysium,
perimysium, endomysium, myoctye, myofibril, sarcomere, myofilaments
what attaches muscle to bone? - answertendons
what attaches bone to bone? - answerligaments
what is a myofibril? - answermodified organelle; second smallest contractile unit
what is a sarcomere? - answersmallest contractile unit of a muscle fiber
what are inside sarcomere? - answermyofilaments
