Nervous System Q
Which activities of the body are controlled by the autonomic nervous system? Voluntary Involuntary All of the above
Involuntary
What is the main function of the spinal cord? It acts as a shock absorber for the vertebrae. It interprets, organizes, and stores information. It carries nutrients to the central nervous system and helps to remove wastes. It carries messages to and from the brain and the nerves that go to the muscles and glands.

Which part of the brain stem connects with the spinal cord? Midbrain Pons Medulla oblongata
Medulla oblongata
What is the general term for the layers of tough membranes that cover and protect the brain and spinal cord? Cerebellum Neurotransmitters Ventricles Meninges
Meninges
In which disease does progressive loss of muscle control result from the destruction of the myelin sheath in the central nervous system? Multiple sclerosis Myasthenia gravis Cerebrovascular accident
Multiple sclerosis
What is the fatty tissue that covers axons and speeds up impulses as they travel from cell to cell? Synapse Myelin sheath Dendrite Neurotransmitter
Myelin sheath
What is another name for a nerve cell? Neuron Synapse Dendrite Axon
Neuron
What is the purpose of the vertebrae? To control reflex actions To control posture To protect the spinal cord To pump cerebrospinal fluid
To protect the spinal cord
Which of these disorders occurs when there is a loss of blood flow, and in turn oxygen, to the brain? Myasthenia gravis Cerebrovascular accident Multiple sclerosis All of the above
Cerebrovascular accident (CVA)
Which section of the brain is concerned with reasoning? Diencephalon Cerebrum Brain stem Cerebellum
Cerebrum
Which section of the brain helps regulate heartbeat and respiration? Cerebellum Brain stem Cerebrum Diencephalon
Brain stem
Which division of the nervous system consists of the brain, spinal cord, and optic nerves? Sympathetic system Peripheral nervous system Autonomic nervous system Central nervous system
Central nervous system
Which section of the brain is responsible for coordinating muscle movements, balance and posture, and muscle tone? Cerebellum Cerebrum Brain stem Diencephalon
Cerebellum
What type of neuron is also called an interneuron because it carries messages between the other two types of neurons? Afferent Associative Efferent
Associative
How does an impulse travel from one neuron to another? Blood carries the impulse from cell to cell. The axon of one cell expands briefly so that it touches the dendrites of the other cell. This information has not yet been discovered. Chemical neurotransmitters help the impulse "jump" across the space between the cells.
Chemical neurotransmitters help the impulse "jump" across the space between the cells.
Which division of the autonomic nervous system prepares the body for action in an emergency? Sympathetic system Parasympathetic system
Sympathetic system
What is the space between a dendrite and an axon called? Ventricle Synapse Neurotransmitter Lobe
Synapse
