17
Q

What allows the cardiac muscle to have action potential spreading?

A

Coupling of desmosomes (mechanical) and gap junctions (electrrical)

18
Q

What allows the cardiac muscle to have action potential spreading?

A

Coupling of desmosomes (mechanical) and gap junctions (electrrical)

19
Q

What does the smooth muscle cells look like when a blood vessel is constricted?

A

Bulging on top

20
Q

When can smooth muscle cells have AP spreading?”

A

In Single units(gap junctions)

21
Q

When can smooth muscle not have AP spreading?

A

In multi unit (absence of gap junctions)

22
Q

What does the no gap junctions allow for?

A

Fine control of individual smooth muscle cells
