Understanding the Nervous System

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

• To control voluntary movements

• To process information sent by the peripheral nervous system and come up with a response

• To regulate heart rate and digestion

• To transmit signals to muscles

Which part of the nervous system is responsible for the "fight or flight" or stress response?

• Central nervous system

• Peripheral nervous system

• Sympathetic nervous system

• Parasympathetic nervous system

What is the role of dendrites in a neuron?

• To transmit impulses away from the cell body

• To receive impulses from other neurons

• To protect the neuron

• To store neurotransmitters

Which part of the nervous system controls involuntary actions like heart rate and digestion?

• Somatic nervous system

• Autonomic nervous system

• Central nervous system

• Peripheral nervous system

What is the function of the axon in a neuron?

• To receive signals from other neurons

• To transmit impulses away from the cell body

• To process and interpret sensory information

• To regulate involuntary actions

Which part of the nervous system is involved in voluntary movements?

• Autonomic nervous system

• Sympathetic nervous system

• Somatic nervous system

• Parasympathetic nervous system

What is the role of the cell body (soma) in a neuron?

• To transmit impulses to other neurons

• To receive signals from other neurons

• To receive an impulse from the dendrite, process it, and send it to the axon

• To protect the neuron
