In a conduction cell like an SA node action potential, what role does calcium play?
Solutions
Expert Solution
Calcium is the ion which contribute to the Major portion of skeleton. And it also helps in impulses transmission.
Calcium has the function of triggering the transmission of neurotransmitter on the post synaptic cleft.
Calcium channel in the post synaptic neuron opens and it receives the neurotransmitters which is essential for impulse transmission.

Describe in detail the action potential of an SA nodal cell of
the heart. Be sure to names the phases, include the main types of
membrane proteins involved, how they are opened, the movements of
ions, and the changes in membrane potential. Explain how this type
of action potential is different from that seen in a skeletal
muscle cell and why the difference(s) are significant.
