Answer 6

action potential

Question 7

Intercolated discs consist of what

Answer 7

Desmosomes and gap junctions

Question 8

What is the purpose of desmosomes in intercolated discs

Answer 8

prevent the heart from ripping itself apart when contracting

Question 9

Gap junctions allow for 2 things

Answer 9

1) rapid communication between cells which leads to uniform contraction 2) behave like open channels for ions to pass
