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
In the depolarized state, the inside of the cell becomes the positive pole and the outside of the cell becomes the negative pole. The increase in membrane potential created between the inside and the outside of the cell during depolarization is called the action potential. Once a cell is excited (depolarized), it can excite adjacent cells and pass on its action potential, spreading depolarization to more and more cells.
