What are the three types of muscular tissue?
skeletal, cardiac and smooth
where is the epimysium found
surrounding the entire muscle
the synapse formed between the axon terminal of a motor neuron and the motor end plate of a muscle fiber is known as
the neuromuscular junction
The three sources of ATP production are:
creatine phosphate, anaerobic cellular respiration, aerobic cellular respiration
a brief contraction of all the muscle fibers in a motor unit in response to a single action potential in its motor neuron is called a...
twitch contraction
true or false: smooth and cardiac muscles produce voluntary muscle contractions
false
Where is the perimysium found?
Surrounding 10-100 muscle fibers
True or false: during the sliding filament mechanism the the I bands and H zones become narrower and eventually disappear when the muscle is maximally contracted
true
Glycolysis occurs during which source of ATP production?
anaerobic cellular respiration
the three phases of a twitch contraction are:
latent period, contraction period and relation period
producing body movements, stability of body positions, storing and moving substances within the body, and producing heat
H zone
What is the muscle fibers main source of energy?
ATP
_________________ provides enough energy for muscles to contract maximally for about 15 seconds.
Creatine phosphate
this muscle fiber is very resistant to fatiguing and are capable of prolonged sustained contractions
slow oxidative fibers
Which muscle tissues have striations?
skeletal and cardiac muscle tissue
True or false: I bands are at the end of one sarcomere. They do not overlap into the sarcomere next to it.
false
Actin
______________ provide most of the needed ATP for activities that last 10 minutes.
Aerobic cellular respiration
these fibers produce contractions that are the most powerful and rapid. These fibers are known for fatiguing very quickly
Give me an example of how muscles move substances through the body
large intestine, small intestine, stomach, esophagus, or any other acceptable answer :)
Name the three proteins that can be found in the sarcomere.
actin, tropomyosin, troponin
Motor units are involuntarily activated to produce a sustained contraction of their muscle fibers. This process results in what?
Muscle Tone
This process produces enough ATP for maximal muscle contractions lasting about 30-40 seconds
aerobic cellular respiration
these muscle fibers have a moderate resistance to fatiguing and they generate ATP through anaerobic glycolysis
fast oxidative glycolytic fibers
