What type of neuron connects sensory and motor neurons?

Back

Interneurons

Front

What is the primary function of the myelin sheath?

Back

To electrically insulate and increase impulse transmission speed.

Front

Which part of a neuron is responsible for generating and transmitting nerve impulses?

Back

Axon

Front

What type of neurons conduct impulses to muscles and glands?

Back

Motor neurons

Front

What does the corpus callosum connect?

Back

The two hemispheres of the brain.

Front

What are the three main types of neurons?

Back

Sensory neurons, motor neurons, and interneurons.

Front

What is the role of sensory neurons?

Back

To carry signals from sensory receptors to the central nervous system.

Front

What is the function of motor neurons?

Back

To transmit signals from the central nervous system to muscles and glands.

Front

What is the significance of the myelin sheath in neural transmission?

Back

It increases the speed of electrical impulses along the axon.

Front

What is the difference between gray matter and white matter in the nervous system?

Back

Gray matter contains neuronal cell bodies, while white matter contains myelinated axons.
