Q: (Lockjaw) a form of spastic paralysis caused by toxin "Clostridium tetani".
Answer:
Tetanus
Q: (Neurotransmitter) found in the spinal cord, normally stopping motor neurons from producing
unwanted muscle contractions.
Answer:
Glycine
Q: Blocks glycine release in the spinal cord and causes overstimulation & spastic paralysis of the
muscles.
Answer:
Tetanus Toxin
Q: A state in which muscles are limp and cannot contract.
Answer:
Flaccid Paralysis
Q: Competes with ACh for receptor sites but does not stimulate the muscles. Used in anesthetics.
Answer:
Curare
Q: A type of food poisoning caused by a neurotransmitter toxin secreted by bacterium
"Clostridium botulinum". Blocks initial release of ACh causing flaccid paralysis.
Answer:
Botulism
Q: The amount of tension generated by a muscle depends on how stretched or shortened it was
prior to stimulation.
Answer:
Length-Tension Relationship
,Q: Produces greatest force when muscle contracts.
Answer:
Optimum resting-length
Q: Hardening of muscles and stiffening of body beginning 3-4hrs after death. Muscles contract
but cannot relax.
Answer:
Rigor Mortis
Q: Releases Ca+2 to enter cytosol.
Answer:
Deteriorating Sarcoplasmic Reticulum
Q: Requires new ATP (ATP production is not produced after death). Fibers remain contracted
until myofilaments begin to decay.
Answer:
Muscle Relaxation
Q: Chart of timing and strength of a muscle's contraction.
Answer:
Myogram
Q: Minimum voltage necessary to generate an action potential in the muscle fiber & produces a
contraction.
Answer:
Threshold
Q: A quick cycle of contraction & relaxation when stimulus is at threshold or higher.
Answer:
Twitch
Q: Very brief delay between stimulus and contraction.
Answer:
Latent Period
Q: Time when muscle generates external tension. Force can overcome the load and cause
movement.
Answer:
Contraction Phase
, Q: Time when tension declines to baseline. SR reabsorbs Ca+2. Myosin releases actin. Tension
decreases; longer contraction.
Answer:
Relaxation Phase
Q: Depends on availability of Oxygen and Organic energy sources (glucose & fatty acids).
Answer:
ATP Supply
Q: Enables cells to produce ATP in the absence of oxygen. Yields little ATP and lactate, which
needs to be disposed of by the liver.
Answer:
Anaerobic Fermentation
Q: Produces far more ATP than anaerobic form. Does not generate lactate & requires continual
supply of oxygen.
Answer:
Aerobic Respiration
Q: Transfers P, from one ADP to another, converting the latter to ATP.
Answer:
Myokinase
Q: P, from a phosphate-storage molecule "Creatine Phosphate" (CP) & gives it to ADP.
Answer:
Creatine Kinase
Q: The combination of (ATP and CP) which provides nearly all energy for short bursts of
activity. Enough energy for 6s of sprinting.
Answer:
Phosphagen System
Q: (Lactate threshold) The point at which lactate becomes detectable in the blood.
Answer:
Anaerobic
Threshold
Q: (Lactate System) The pathway from glycogen to lactate Produces enough ATP for 30-40s of
maximum activity.
Answer:
Glycogen
