Nervous System

Which of the following is the main function of the nervous system?

• to transport nutrients and oxygen throughout the entire body

• to break down food into nutrient molecules and absorb them

• to inhale oxygen and exhale carbon dioxide

• to detect stimuli and respond in order to maintain homeostasis

Which of the following are organs in the CENTRAL nervous system? (Choose all that apply)

• Brain

• Spinal Cord

• Sensory Neuron

• Motor Neuron

Which of the following does the PERIPHERAL nervous system consist of?

• Brain

• Spinal Cord

• Sensory Neuron

• Motor Neuron

What does the AUTONOMIC part of the peripheral nervous system control?

• voluntary actions

• involuntary actions

• semi-voluntary actions

• automatic actions

What does the SOMATIC part of the peripheral nervous system control?

• voluntary actions

• involuntary actions

• semi-voluntary actions

• automatic actions

What is the function of the SENSORY neurons?

• Carry the nerve impulses inside the spinal cord or brain to another interneuron or motor neuron

• Nothing. There is no such thing as a sensory neuron

• Detect stimuli and convert them into nerve impulses which travel to the spinal cord and/or brain

• Receive nerve impulses from interneurons and send them to muscles and glands, which enables the muscles and glands to respond

What is the function of the INTERNEURONS?

• Carry the nerve impulses inside the spinal cord or brain to another interneuron or motor neuron

• Nothing. There is no such thing as a sensory neuron

• Detect stimuli and convert them into nerve impulses which travel to the spinal cord and/or brain

• Receive nerve impulses from interneurons and send them to muscles and glands, which enables the muscles and glands to respond

What is the function of the MOTOR neurons?

• Carry the nerve impulses inside the spinal cord or brain to another interneuron or motor neuron

• Nothing. There is no such thing as a sensory neuron

• Detect stimuli and convert them into nerve impulses which travel to the spinal cord and/or brain

• Receive nerve impulses from interneurons and send them to muscles and glands, which enables the muscles and glands to respond

Which part of the nervous system are INTERNEURONS a part of?

• Central Nervous System

• Peripheral Nervous System

What is homeostasis?

• the ability to respond to stimuli in order to keep body conditions relatively constant

• the ability to sleep whenever you feel like it

• the ability to run for as long as you want without becoming tired

• the ability to keep conditions inside the body constant for as long as you want, no matter what environment you may be in.
