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
When a neuron is activated by a stimulus of adequate intensity, known as a. threshold stimulus, the membrane at its trigger zone, typically the axon hillock, briefly becomes more permeable to sodium ions (sodium gates in the cell. membrane open.) Sodium ions rush into the cell, increasing the number of.
