HBS 2.1 Review

Front

Lobe of brain associated with body sensations: touch, temperature, pain

Back

Parietal lobe

Front

Main structures/parts of the nervous system

Back

Brain, spinal cord, peripheral nerves

Front

What is the -55mV charge called that is needed for a neuron's axon to reach in order for an action potential to travel down the neuron?

Back

Threshold

Front

What type of channels are Na+ and K+ classified as?

Back

Voltage-gated channels

Front

During depolarization of an axon, which ion is traveling in LARGE amounts into the axon?

Back

Sodium (Na+) ions

Front

Function of the frontal lobe

Back

Involved in reasoning, planning, problem-solving, and emotional regulation.

Front

Role of the spinal cord in the nervous system

Back

Transmits signals between the brain and the rest of the body.

Front

What is depolarization in the context of neuron activity?

Back

The process where the membrane potential becomes less negative (more positive) due to the influx of sodium ions.

Front

What is repolarization in neuron activity?

Back

The process of returning the membrane potential to a more negative value after depolarization.

Front

What is hyperpolarization?

Back

An increase in the membrane potential, making it more negative than the resting potential.
