We know that the sum of the measures of any triangle is 180 degrees. Using the fact that angle A + angle B + angle C = 180 degrees, we can find the measure of angle C. angle A = 40. angle B = 60. angle C = we don't know.
When a depolarization wave reaches the synaptic end bulb of a presynaptic neuron, the NEXT event is diffusion of calcium ions into the cell A neurotransmitter that allows sodium ions to leak into a postsynaptic neuron causes
If the axon hillock on the postsynaptic neuron reaches threshold potential then an impulse is transmitted and action potential is reached all over again. It is either inhibitory and nothing happens or excitatory and causes depolorization again. If the axon hillock on the postsynaptic neuron reaches threshold potential then an impulse is transmitted and action potential is reached all over again.
