The Nervous System
The body's speedy, electrochemical communication network, consisting of all the nerve cells of the peripheral and central nervous systems.
The Nervous System
Involved in memory, learning, and emotion.
Made the theory of natural selection
Charles Darwin
Drugs (such as alcohol, barbiturates, and opiates) that reduce neural activity and slow body functions.
Depressants
Neuron's life support center
Cell Body
The part of the peripheral nervous system that controls the glands and the muscles of the internal organs (such as the heart). Its sympathetic division arouses; the parasympathetic division calms.
Autonomic Nervous System
Main function is to keep your body in a stable state called homeostasis?
Made the theory that dreams had an underlying meaning
Sigmund Frued
Drugs that depress the activity of the central nervous system, reducing anxiety but impairing memory and judgment.
Barbiturates
The passage through which neurons transmit messages
Axon
Neurons within the brain and spinal cords; they communicate internally and process information between the sensory and motor outputs
Interneurons
Frontal Lobe
Discovered the two specialized language brain areas
Paul Broca and Carl Wernicke
A drug that depresses neural activity, temporarily lessening pain and anxiety.
Opiates
Neurons message receivers
Dendrites
Most influential gland in the endocrine system
The pituitary gland
Located at the back of the school. Coordinates muscular activity.
Cerebellum
Named the continuous stream of consciousness
William James
Drugs that excite neural activity and speed up body functions.
Stimulants
Covers the axon of some neurons and helps speed up neural messages
Myelin Sheath
The body's "slow" chemical communication system; a set of glands that secrete hormones into the bloodstream
Endocrine System
Mediates emotional learning as well as emotional behavior.
Amygdala
Scientist who discovered dissociation
Earnest Hillgard
A regular sequence of biological processes, such as temperature and sleep, that occurs every 24 hours.
Circadian Rhythm
Action potential; electrical signal traveling down the axon
Neural Impluse
