3] Discuss the concept that the nerve cell evolved from a cell that interacted with other cells using electrical synapse into the neuron that conveys specific unidirectional information that can be used to regulate other cells. Approach this discussion from the perspective of the processes that are responsible for the facilitating and inhibiting input that regulate the function of the cardiac pacemaker.
Include:
A) the mechanisms by which this regulation is transduced in the post synaptic membrane and how this affects the components of the movement of blood by the heart.
B) consider how the stimuli associated with homeostasis(pressure pH heart rate) are transduced into changes in the output of the heart to insure O2/CO2 homeostasis at the level of individual cells?
