Nervous System

Front

What part of the neuron stores neurotransmitters?

Back

Axon terminals

Front

During which phase of action potential events are Na/K pumps most active?

Back

Hyperpolarization

Front

What part of the neuron receives signals?

Back

Dendrites

Front

During which phase does potassium (K+) rush out of the cell?

Back

Repolarization

Front

Which cerebral lobe is responsible for reasoning and problem-solving?

Back

Frontal lobe

Front

What is the primary function of dendrites?

Back

To receive signals from other neurons.

Front

What is the role of the axon in a neuron?

Back

To transmit electrical impulses away from the cell body.

Front

What is the resting membrane potential of a neuron?

Back

Typically around -70 mV.

Front

What occurs during depolarization?

Back

Sodium (Na+) channels open, allowing Na+ to enter the cell.

Front

What is hyperpolarization in the context of action potentials?

Back

An increase in membrane potential, making the inside of the cell more negative.
