- nervous system
- a the "little brain" at the rear of the brainstem; functions include processing sensory input and coordinating movement output and balance.
- b the body's speedy, electrochemical communication network, consisting of all the nerve cells of the peripheral and central nervous systems.
- c failure to see visible objects when our attention is directed elsewhere.
- d the brain and spinal cord.
- e the division of the peripheral nervous system that controls the glands and the muscles of the internal organs (such as the heart). Its sympathetic division arouses; its parasympathetic division calms.

- recurring sleep stage during which vivid dreams commonly occur. Also known as paradoxical sleep, because the muscles are relaxed (except for minor twitches), but other body systems are active.
- the biological clock; regular-bodily rhythms (for example, of temperature and wakefulness) that occur on a 24-hour cycle.
- the sensory and motor neurons connecting the central nervous system (CNS) to the rest of the body.
- neurons that communicate internally and intervene between the sensory inputs and motor outputs.
- the junction between the axon tip of the sending neuron and the dendrite or cell body of the receiving neuron.
5 True/False questions
medulla → a nerve cell; the basic building block of the nervous system.
hallucinations → neurons that carry outgoing information from the central nervous to the muscles and glands.
insomnia → recurring problems in falling or staying asleep.
frontal lobes → portion of the cerebral cortex lying at the top of the head and toward the rear; receives sensory input for touch and body position.
opiates → chemicals, such as opium, morphine, and heroin, that depress neural activity, temporarily lessening pain and anxiety.
