Q

Blank gate that opens by projection

A

Calcium

26
Q

Spot on sarcolemma where the neuron with communicate with

A

Motor endplate

27
Q

The thing that starts a action

A

Motor neuron

28
Q

Where the neuron meets the muscle

A

Neuromuscular junction

29
Q

Name of the neurotransmitter for muscle

A

Acetylcholine

30
Q

One neuron and all the fibers it controls
Around (200-1000)

A

Motor units

31
Q

Take the energy out of food to make this

A

ATP

32
Q

How much ATP is in the human body at a time

A

2-3 seconds

33
Q

You use this to make ATP

A

Creative Phosphate

34
Q

You carry this much creatine phosphate at a time

A

6 seconds

35
Q

Metabolizing food without oxygen

A

Anaerobic respiration

36
Q

How is Latic acid made?

A

Glucose transforms into something else and pyruvate is a byproduct. This byproduct sits out side a cell’s mitochondria slowly getting sucked in. If it sucks in slower then it’s created the pyruvate is turned into latic acid

37
Q

How long can a person anaerobic for

A

30- 40 seconds

38
Q

Metabolize food with oxygen

A

Aerobic respiration

39
Q

Happens after a exercise when you breath heavy

A

Oxygen debt

40
Q

4 things that happen when recovering from oxygen debt

A

1, restores ATP
2, puts creatine back together
3, you heart gets rid of the Latic acid
4, repair(strenuous exercise breaks tissue)

41
Q

How many ATP per glucose

A

38

42
Q

What happens with more PH

A

Reactions happen slower, which means you move slower

43
Q

Slow twitch
Primary in legs

A

Type 1

44
Q

Fast twitch
In legs

A

Type 2a

45
Q

Fast twitch explosive power
In arms

A

Type 2b

46
Q

Molecules that hold oxygen

A

Myoglobin

47
Q

Same tension curls the weight and gravity stays the same

A

Isotonic

48
Q

Same length and holding out a book for posture

A

Isometric

49
Q

Same speed, artificial and always moves the same speed

A

Isokinetic

50
Q

Same muscles doing the same actions

A

Q

Gets more small motor units first and slowly gathers more

A

Recruitment

59
Q

Muscle around the inside of body
Everywhere in body

A

60
Q

40% mitochondrial tissue so it”s never anaerobic and no oxygen debt
In heart only

A

Cardiac muscle
