Front

What is the purpose of the myelin sheath on the axon?

Back

Front

In a neuron, what does the letter 'A' represent when labeling the parts?

Back

Dendrite.

Front

What part of the neuron releases neurotransmitters into the synaptic cleft?

Back

Front

What do sensory neurons carry nerve impulses from?

Back

Sense organs and internal organs (like your stomach).

Front

What is the central nervous system (CNS) composed of?

Back

The brain and spinal cord.

Front

What is the function of dendrites in a neuron?

Back

To receive signals from other neurons.

Front

What is the role of neurotransmitters in the nervous system?

Back

To transmit signals across the synaptic cleft between neurons.

Front

What is the difference between afferent and efferent neurons?

Back

Afferent neurons carry signals to the CNS, while efferent neurons carry signals away from the CNS.

Front

What is the significance of the synaptic cleft?

Back

It is the gap between neurons where neurotransmitters are released.
