Document Summary
Q8: how did dr. kass accomplish smooth movements with a low weight? a. high ap rate, using a few m. n. s, b. low ap rate, using many motor neurons, c. high ap rate, using many m. n. s, d. Low ap rate, using just a few m. n. s. Q9: __ is primarily red sk. muscle? a. ocular muscle, b. gastrocnemius muscle, c. soleus muscle, d. a-c all red sk muscle, e. none of the above. Whole muscle contraction: muscle twitch= a single stimulus contraction-relaxation cycle in a muscle ber, myogram= graph of the tension (force) produced by a muscle during a twitch at various times. Gravity and antagonistic muscle stretching: muscle tone. Atrophy= dying muscle bers and loss of sarcomere units: energetics. Small resting muscle reserves of atp: most energy stored in creatine phosphate (cp) cp recharges adp during muscle contractions via creatine phosphokinase. Atp generated at - rate of use. Skeletal muscle types: white muscle (fast twitch)
