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
Positive charges exist on the outside of the axon and negative charges on the inside. Now consider the consequences of delivering some stimulus to a point in the middle of the axon. If the depolarization is sufficiently large, voltage-dependent sodium channels will be opened, and an action potential will be initiated.
