Neuron, Synapse and Action Potential

Front

What is the function of the autonomic nervous system?

Back

The autonomic nervous system controls involuntary bodily functions such as heart rate, digestion, and respiratory rate.

Front

Where are neurotransmitters stored in a neuron?

Back

Neurotransmitters are stored in the axon terminals of a neuron.

Front

What part of a neuron receives signals from other neurons?

Back

Dendrites receive signals from other neurons.

Front

What is the resting membrane potential of a neuron?

Back

The resting membrane potential is when the inside of the neuron is more negative compared to the outside, typically around -70mV.

Front

What does the axon do in a neuron?

Back

The axon transmits electrical impulses away from the cell body to other neurons or muscles.

Front

What is the role of myelin sheath in a neuron?

Back

The myelin sheath insulates the axon and increases the speed of electrical impulses.

Front

What is an action potential?

Back

An action potential is a rapid change in the electrical charge of a neuron that occurs when it is stimulated, leading to the transmission of a nerve impulse.

Front

What is the synapse?

Back

The synapse is the junction between two neurons where neurotransmitters are released to transmit signals.

Front

What happens during depolarization in a neuron?

Back

During depolarization, sodium ions enter the neuron, making the inside more positive and triggering an action potential.

Front

What is the function of Schwann cells?

Back

Schwann cells produce the myelin sheath that insulates axons in the peripheral nervous system.
