Movement of hair-cell cilia in a direction that results in the decrease of neurotransmitter release is called:

A) hyperpolarization.
B) polarization.
C) depolarization.
D) hypopolarization.

Hyperpolarization

An increase in a cell's membrane potential, making it more negative and less likely to fire an action potential.

Neurotransmitter Release

The process by which neurons release chemical messengers into the synaptic cleft, allowing them to communicate with adjacent cells.

Decrease

Decrease refers to a reduction in quantity, size, intensity, or the level of something.
