Ap Psychology Chapter 3 Summary
Psychology chapter three vocabulary nervous system, a collection of hundreds of billions of specialized and interconnected cells through which messages are sent between the brain and the rest of the body.
The nervous system consists of the central nervous system (CNS), made up of the brain and the spinal cord, and the peripheral nervous system (PNS), the neurons that link the CNS to our skin, muscles, and glands. And we will see that our behavior is also influenced in large part by the endocrine system, the chemical regulator of the body that consists of glands that secrete hormones.
A neuron is a cell in the nervous system whose function it is to receive and transmit information soma, which contains the nucleus of the cell and keeps the …show more content…
It’s also used in the brain to regulate memory, sleeping, and dreaming.
Alzheimer’s disease is associated with an undersupply of acetylcholine. Nicotine is an agonist that acts like acetylcholine. Dopamine Involved in movement, motivation, and emotion,
Dopamine produces feelings of pleasure when released by the brain’s reward system, and it’s also involved in learning.
Schizophrenia is linked to increases in dopamine, whereas Parkinson’s disease is linked to reductions in dopamine (and dopamine agonists may be used to treat it). Endorphins Released in response to behaviors such as vigorous exercise, orgasm, and eating spicy foods.
Endorphins are natural pain relievers. They are related to the compounds found in drugs such as opium, morphine, and heroin. The release of endorphins creates the runner’s high that is experienced after intense physical exertion.
GABA (gammaaminobutyric acid) The major inhibitory neurotransmitter in the brain.
A lack of GABA can lead to involuntary motor actions, including tremors and seizures. Alcohol stimulates the release of GABA, which inhibits the nervous system
