muscle test questions Flashcards
how many muscles are in the human body
about 650
3 primary functions of the muscular system
movement, support, circulation
3 types of muscle tissue
skeletal, cardiac, smooth
what is the purpose/function of skeletal muscles
locomotion and maipulation, voluntary
purpose of cardiac muscles
beats heart and pumps blood involuntary
purpose of smooth muscles
allows things to slide through organs, involuntary
what does skeletal muscle attach to
tendons
what is atp
provides energy to cells
what happens when muscles become to acidic
become fatigue and stops muscles from contracting
6 steps in creating action potentail
ATP binding, ADP release, ATP hydrolysis, weak cross-bridge attachment, power stroke, and release of phosphate from myosin.
eccentric vs concentric contraction
concentric means the muscle gets shorter, eccentric is when the muscle lengthens
3 benefits of physical activity
lower risk of heart disease, stronger muscles, function better
what does resistance training involve
physical activity that improves muscle fitness by excersising a muscle
difference between muscular strength and muscular endurance
strength is how heavy you can lift, endurance is how long you can go without getting tired
sarcopenia
age related muscle loss
