What is the main function of the central nervous system (CNS)?

Back

The CNS processes information and coordinates responses; it consists of the brain and spinal cord.

Front

What is the role of the synapse in the nervous system?

Back

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

Front

What are interneurons and what is their function?

Back

Interneurons are neurons that connect sensory neurons to motor neurons, facilitating communication within the nervous system.

What is the function of sensory neurons?

Back

Sensory neurons transmit sensory information from receptors to the central nervous system.

Front

What is the role of motor neurons?

Back

Front

What is the function of the spinal cord in the nervous system?

Back

The spinal cord transmits signals between the brain and the rest of the body and coordinates reflexes.

Front

What is a neurotransmitter?

Back
