Q

myo fribril is made up of ???

A

myoilaments

30
Q

A motor neuron and all of the skeletal muscle cells it stimulates is called a ???. . The axon of each motor neuron has numerous endings called ???. The actual gap between an axonal ending and the muscle cell is called a ???. Within the axonal endings are many small vesicles containing a neurotransmitter substance called ??

A

motor unit , axon terminals, synaptic cleft, ACH

31
Q

When the ________________________ reaches the ends of the axon, the neurotransmitter is released, and it diffuses to the muscle cell membrane, called the _____________________, to combine with receptors there.Binding of the neurotransmitter with muscle membrane receptors causes the membrane to become permeable to sodium, resulting in the influx of sodium ions and ________________________of the membrane.

A

nerve imoulse, sarcolema , depolorization

32
Q

steps of contraction of muscle ?

ACH is ???. ACH diffuese across ??? and binds to ???, depolarzation and ??? occur. rleases ???. and myofilaments slide past one another, and the cell ??? . As ??? is actively reabsorbed into the sarcoplasmic reticulum. then the muscle cell ??? and leghtehsn

A

released , NMJ, receptors, action potentail , calcium, shortens, calcium, relaxes

33
Q

Calcium binds to troponin.?

A

contraction

34
Q

An impulse travels along the sarcolemma?

A

contraction

35
Q

Calcium is reabsorbed into the sarcoplasmic reticulum?

A

relaxation

36
Q

Myosin heads interact with actin?

A

contraction

37
Q

Z line get further apart.?

A

relaxation

38
Q

I bands seem to disappear.?

A

co0ntraction

39
Q

ATP binds myosin heads?

A

relaxation

40
Q

Actin molecules slide toward the M-line of the sarcomere?

A

contraction

41
Q

??? is a continuous contraction that shows no evidence of relaxation

A

tetanus

42
Q

______ is a contraction in which the muscle shortens and work is done.

A

Concentric isotonic contraction

43
Q

To accomplish a strong contraction, ______ are stimulated at a rapid rate?

A

many motor units

44
Q

When a weak but smooth muscle contraction is desired, ______ are stimulated at a rapid rate.

A

few motor neurons

45
Q

When a muscle is being stimulated but is not able to respond due to “oxygen debt,” the condition is called ___

A

fatigue

46
Q

A(n) ______ is a contraction in which the muscle does not shorten but tension in the muscle keeps increasing.

A

isometric contraction

47
Q

Briefly describe how you can tell when you are repaying the oxygen debt?

A

bretahe rapidly

48
Q

what happens durong oxygen debt?

atp
