Flashcards

QuestionAnswer
Endomysium Delicate connective tissue membrane that covers skeletal muscle fibers
Perimysium Tough connective tissue binding together fascicles
Epimysium Coarse sheath covering the muscle as a whole
Contractility Muscle cells ability to contract or shorten, allows muscle tissue to pull on bones and thus produce body movement.
Extensibility, The ability to extend or stretch, allows muscles to return to their resting length after having contracted
4 protein molecules that make up myofilaments Myosin, Actin, Tropomyosin, and Troponin.
ATP - adenosine triphosphate Provides energy required for muscular contraction, nerve impulse and chemical synthesis
Muscle fatigue Result of repeated stimulation of muscle in time, lessens its excitability and contractility
Muscle recruitment Factor that influences the grade of strength exhibited by a muscle organ is the number of fibers contracting simultaneously
Isotonic contraction Contraction in which the tone or tension within a muscle remains the same as the length of the muscle changes
