Quizizz Quiz: Neurons

What is the basic structural unit of the nervous system?

• Neuron

• Axon

• Dendrite

• Synapse

Which part of the neuron is responsible for receiving signals from other neurons?

• Axon

• Dendrite

• Soma

• Myelin sheath

Identify the part of the neuron that transmits electrical impulses away from the cell body.

• Axon

• Dendrite

• Synapse

• Nucleus

Explain how the myelin sheath affects the speed of nerve impulse transmission.

• It slows down the transmission.

• It has no effect on transmission speed.

• It speeds up the transmission.

• It reverses the direction of transmission.

Which of the following best describes the function of the synapse in neural communication?

• It stores neurotransmitters.

• It is the site where neurotransmitters are released to communicate with other neurons.

• It generates electrical impulses.

• It insulates the axon.

Compare the roles of dendrites and axons in a neuron.

• Both transmit signals away from the cell body.

• Dendrites receive signals, while axons transmit signals away from the cell body.

• Both receive signals from other neurons.

• Dendrites transmit signals, while axons receive signals.

Analyze how damage to the myelin sheath might affect neural communication.

• It would have no effect on neural communication.

• It would increase the speed of neural communication.

• It would slow down or disrupt neural communication.

• It would cause neurons to generate more electrical impulses.

Predict the impact on neural function if a neuron's axon is severed.

• The neuron would continue to function normally.

• The neuron would be unable to transmit signals to other neurons.

• The neuron would generate more signals.

• The neuron would become more sensitive to stimuli.

Evaluate the importance of neurotransmitters in the synaptic transmission process.

• They are not important for synaptic transmission.

• They are crucial for transmitting signals across the synapse.

• They only play a minor role in synaptic transmission.

• They are important for insulating the axon.
