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
At excitatory synapses, the ion channel typically allows sodium into the cell, generating an excitatory postsynaptic current. This depolarizing current causes an increase in membrane potential, the EPSP.
