100
nervous system made of brain and spinal cord
What is the central nervous system?
100
lobe of the brain that receives the processes messages from the skin, senses, such as warmth, cold, touch, and pain
what is temporal lobe?
100
occurs during REM sleep mostly, but can also occur at any stage of sleep. Sigmund Freud believed that this reflects unconscious urges or wishes
What are dreams?
100
slows the activity of the nervous system; alcohol, valium, Xanax
What is depressants?
100
hearing or auditory processing occurs in this lobe of the brain
What is the temporal lobe?
200
part of brain linked to emotion; specifically anger and fear
What is the amyglada?
200
the light sensitive inner surface of the eye; contains the receptor rods and cones plus layers of neurons that begin the processing of visual information
what is retina?
200
the sleep disorder that is the inability to fall asleep; it is usually caused by stress
What is insomnia?
200
too little of this chemical can lead to Alzheimer's disease
What is acetycholine?
200
area of left hemispere that controls speech muscles; damage to this area would result in a person struggling to form words
What is broca's?
300
the lobe of the brain with executive functions such as making decisions, planning, reasoning, and carrying out actions.
What is the frontal lobe?
300
theory that suggests only a certain amount of information can be processes by the central nervous system at a time; rubbing or scratching a painful area transmits sensations to the brain that competes with the pain messages for attention
what is gate theory?
300
sleep disorder that involves an interruption in breathing
What is sleep apnea?
300
chemical involved in motor messages and behavior; if a person has too little of this chemical, they may suffer from Parkinson's disease, too much leads to schizophrenia
What is dopamine?
300
hemipshere of the brain that controls language and logic
What is the left hemisphere?
400
hemisphere of the brain that controls spatial behavior and artisitc efforts
what is the right hemisphere?
400
acts like a drug to reduce pain as well as help transmit messages; it is the natural "morphine" in our bodies and can produce a "runner's high
what are endorphins?
400
sleep disorder which causes a person to fall asleep at unpredictable intervals; this condition is very rare and dangerous
What is narcolepsy?
400
stored in sacs in the axon terminal; chemical messages that cross over to the next nerve cell
What is neurotransmitters?
400
coiled, bony, fluid-filled tube in the inner ear; sound waves traveling through the fluid inside trigger nerve impulses
What is cochlea?
500
the structure of the brain that connects & relays messages between the two hemispheres; severed in extreme cases of epilepsy
what is the corpus callosum?
500
process by which our sensory receptors and nervous system take in stimulus energies from the environment
process by which our sensory receptors and nervous system take in stimulus energies from the environment
500
recurring sleep stage during which vivid dreams commonly occur; also known as paradoxial sleep, because the muscles are paralyzed but the brain is active
What is REM?
500
located at the end of a nerve cell and receive messages (incoming chemicals) from other nerve cells
What is dendrites?
500
stretching from the hindbrain through to the midbrain and into the forebrain this system is important in the regulation of attention and alertness; if this system isn't working well Attention Decifit Disorder may result, when this system is completely impaired , the individual is in a coma
What is reticular activating system?
