Unit 5 Nervous System Test Review

What is the primary function of the nervous system?

• Thinking
• Movement
• Internal physiological processes
• All of the above

How does the nervous system integrate sensory input and produce a motor response?

• By storing information
• By transmitting information to other parts of the body
• By processing and integrating the information, then producing a motor response
• By processing sensory input without producing a motor response

What are the two main types of cells found in the nervous system?

• Neurons and muscles
• Neurons and bones
• Neurons and neuroglia
• Neuroglia and muscles

What is the role of neuroglia in the nervous system?

• To communicate with other cells
• To support and protect neurons
• To produce electrical impulses
• To store information

What are neurotransmitters and how do they play a role in the nervous system?

• Chemical messengers that transmit electrical impulses from one neuron to another
• Electrical impulses that transmit information from one neuron to another
• Structures that support and protect neurons
• None of the above

What are the two major divisions of the nervous system?

• Sensory and motor
• Central and peripheral
• Autonomic and somatic
• Sympathetic and parasympathetic

Gray matter within the cerebral cortex is mainly made up of what neuronal structure?

• neural cell bodies

• axons and their myelin sheaths

• satellite cells

• oligodendrocytes

White matter within the cerebrum is mainly made up of what neuronal structure?

• neural cell bodies

• axons and their myelin sheaths

• satellite cells

• oligodendrocytes

What organs are included in the central nervous system?

• Cranial and spinal nerves
• Sensory receptors
• Brain and spinal cord
• Muscles and glands

What is the sensory (afferent) division of the PNS responsible for?

• Conducting impulses from the CNS to effectors
• Bringing information into the CNS with sensory receptors
• Controlling cardiac muscle, smooth muscle, and various glands
• Controlling skeletal muscles
