AP Test Review Nervous Systems

What is the basic structural unit of the nervous system?

• neuron

• cell

• muscle

• bone

Which type of nerve cells transmit signals from the body to the brain?

• Sensory neurons

• Motor neurons

• Photoreceptors

• Interneurons

Which part of the nervous system consists of the brain and spinal cord?

• somatic nervous system

• peripheral nervous system

• autonomic nervous system

• central nervous system

What is the function of the peripheral nervous system?

• Regulating body temperature and metabolism.

• Transmitting information between the central nervous system and the rest of the body.

• Controlling voluntary movements of the body.

• Producing and releasing hormones.

Which division of the nervous system controls involuntary actions?

• peripheral nervous system

• autonomic nervous system

• central nervous system

• somatic nervous system

What are the three main parts of a neuron?

• nucleus, cytoplasm, cell membrane

• soma, synapse, myelin sheath

• axon terminal, neurotransmitter, synaptic cleft

• cell body, dendrites, axon

What is the function of sensory neurons?

• Transmit information from the central nervous system to sensory receptors.

• Transmit information from sensory receptors to the peripheral nervous system.

• Transmit information from sensory receptors to the central nervous system.

• Transmit information from the central nervous system to motor neurons.

Which part of the nervous system is responsible for voluntary movements?

• autonomic nervous system

• central nervous system

• peripheral nervous system

• somatic nervous system

What are the two main divisions of the autonomic nervous system?

• voluntary and involuntary

• sympathetic and parasympathetic

• somatic and autonomic

• central and peripheral

What is the role of motor neurons?

• Motor neurons are responsible for transmitting signals between sensory neurons.

• Motor neurons have no role in the nervous system.

• Motor neurons transmit signals from the central nervous system to the muscles.

• Motor neurons transmit signals from the muscles to the central nervous system.
