Vocabulary
100
the gap that occurs between individual nerve cells
What is a synapse
100
comes from the Latin word "little brain". Deals with coordination, movement, posture, and balance
What is the cerebellum
100
chemical substances that carry messages through the body in blood
What are hormones
100
part of the brain that covers the brain's central core
What is the forebrain
100
the long, thin cells of nerve tissue along which messages travel to and from the brain
What are neurons
200
smalll fibers that branch out at the end of an axon
What is an axon terminal
200
Large band of fibers through which information flows back and forth between the left and right hemispheres of the brain
What is the corpus callosum
200
known as the "master gland", it produces a variety of hormones and controls the amount of hormones other endocrine glands produce
What is the pituitary gland
200
nerves branching out from the spinal cord
What is the peripheral nervous system
200
the genetic transmission of characteristics from parents to their offspring
What is heredity
300
long fiber that carries the impulses away from the cell body
What is an axon
300
Controls breathing, circulation, heartbeat, and digestion
What is the medulla
300
This gland becomes active when a person in angry or afraid. In releases epinephrine and norepinephrine which causes heartbeat and breathing to increase.
What are the adrenal glands
300
part of the brain located at the rear base of teh skull that is involved in the basic processes of life
What is the hindbrain
300
a machine used to record the electrical activity of large portions of the brain
What is an electroencephalograph
400
short, thin fibers that stick out from the cell body and receive impulses from other neurons
What are dendrites
400
Outer layer of the brain that covers both brain hemispheres. gives you the ability to learn, store complex and abstract information
What is the cerebral cortex
400
This gland produces the hormone thyroxine
What is the thyroid gland
400
Lobes of the brain and their functions
What is the occipital lobe - back of the brain in charge of processing visual signals, parietal lobe- top of the brain in charge of making sense of all the sensory information that comes into the brain, temporal lobe- by the temples or ears sides of the brain deals with hearing, memory, emotion and speaking, and frontal lobe -front of the brain concerned with organization, planning, and creative thinking.
400
an imaging technique used to study the brain structure and activity
What is Magnetic Resonance Imaging
500
white, fatty substance that insulates and protects the axon from some neurons
What is the myelin sheath
500
The Four (4) parts of the limbic system and their functions
What is the thalamus - the relay station that directs information going into the brain; hypothalamus - regulates body temperature and monitors hormone levels; hippocampus - helps establish long term memory in regions of the cerebral cortex; amygdala - controls fear, rage, and violence. and is Latin for the word "almond"
500
differences between hormones and neurotransmitters
hormones are released in to the bloodstream by the glands using slower, widespread communication (few minutes) neurotransmitters are a chemical electrical message sent by neurons which determine the rate at which other neurons fire. The communication is rapid and specific.
500
three types of neurons and how they function
What are afferent, efferent, and interneuron
500
Imaging system that observes both the functions of different structures of the brain and which structures participate in specific functions. Does not require radio frequenies
What is functional magnetic resonance imaging
