A
  1. Smooth
  2. Cardiac
  3. Skeletal
62
Q

How to differentiate histological slides of cardiac and striated muscle?

A

Binding of ACh to ACh receptors

81
Q

What is ACh broken down by

82
Q

Why is ACh broken down?

A

So that the muscle can stop contracting

83
Q

After muscle contraction, how do Ca2+ return to the sarcoplamic reticulum?

A

Active transport pump, that uses ATP

84
Q

What is tension in the muscle dependent on?

A

The number of cross bridges between actin and myosin

85
Q

What is the relationship between degree of stretch and tension?

86
Q

3 main phases of a twitch

A
  1. Latent period
  2. Contraction peroid
  3. Relaxation peroid
87
Q

What is treppe, in terms of muscle contraction?

A

If the 2nd stimulation occurs immediately after the end of the relaxation phase, the next contraction will be slightly bigger.

88
Q

What is incomplete tetanus?

A

Summation of contractions just after start of relaxation peroid. slowly induces tension.

89
Q

What is incomplete tetanus?

A

Increasing stimulating frequency, eliminating the relaxation phase. contraction occurs upto maximum tension.
