Nervous System Video Review

What is the main function of the nervous system?

• Controlling muscle movement

• Producing hormones

• Regulating body temperature

• Digesting food

Which part of the nervous system is responsible for analyzing and interpreting data?

• Central nervous system

• Peripheral nervous system

• Somatic nervous system

• Autonomic nervous system

What are the two main departments of the nervous system?

• Somatic and autonomic

• Central and peripheral

• Sympathetic and parasympathetic

• Afferent and efferent

What are afferent neurons also known as in the peripheral nervous system?

• Motor neurons

• Sympathetic neurons

• Parasympathetic neurons

• Sensory neurons

Which division of the autonomic nervous system is responsible for the fight-or-flight response?

• Sympathetic division

• Parasympathetic division

• Somatic division

• Afferent division

What is the process called when an action potential travels down a neuron?

• Reflex loop

• Saltatory conduction

• Synapse

• Exocytosis

What is the resting potential of a neuron?

• -70 millivolts

• -30 millivolts

• -50 millivolts

• 0 millivolts

What happens when an action potential reaches the end of a neuron?

• The myelin sheath is formed

• The neuron becomes inactive

• The resting potential is restored

• Neurotransmitters are released

What is the purpose of the sympathetic division of the autonomic nervous system?

• To prepare the body for action

• To regulate digestion

• To promote relaxation and rest

• To control voluntary movements

What is the function of the somatic nervous system?

• To regulate hormone production

• To process sensory information

• To control voluntary body movements

• To control involuntary body functions
