Unit 6 Lesson 3 Muscle Response Practice Quiz

time between application of a stimulus and the beginning of a response in a muscle fiber

• latent period
• muscle impulse
• summation
• threshold stimulus

a neuron that transmits impulses from the central nervous system to an effector

• motor neuron
• summation
• sarcomeres
• myofibrils

a motor neuron and its associated muscle fibers

• motor unit
• peristalsis
• sarcomeres
• synapse

the amount of oxygen required after physical exercise to convert accumulated lactic acid to glucose

• oxygen debt
• recruitment
• contracture
• threshold stimulus

increase in number of motor units that are activated as stimulation intensity increases

• recruitment
• summation
• tetanic contraction
• twitch

increased force of contraction by a skeletal muscle fiber when a twitch occurs before the previous twitch relaxes

• summation
• tetanic contraction
• twitch
• contracture

continuous, forceful muscular contraction without relaxation

• tetanic contraction
• twitch
• summation
• contracture

stimulation level that must be exceeded to elicit a nerve impulse or a muscle contraction

• threshold stimulus
• latent period
• synapse
• muscle impulse

a brief contraction of a muscle fiber followed by relaxation

• twitch
• threshold stimulus
• summation
• latent period

What is the energy source that is used for all contractions?

• Glucose

• Creatine

• ATP

• Oxygen
