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
By an action potential, which is a depolarization of the nerve cell membrane, the neurolemma. A nerve impulse gets transmitted along an axon in 5 steps: 1) Stimulus opens Sodium ion (Na+) channels at Resting Potential.y a change in polarity as sodium ions enter the cell and potassium ions exit the cell, forming a wave of depolarization that travels along the axon until it reaches the axon terminal releases the neurotransmitters into the synaptic gap.
