Structure of Neuron
What is the purpose of the dendrites?
A neurons often bushy, branching extensions that receive and integrate messages, conducting impulses toward the cell body.
What do neurotransmitters cross inorder to bind to the receiving neuron?
Synaptic Gaps
What is the nervous system?
A communication network that takes and information from the world and the bodies tissues. Makes decisions, and sends back information and orders to the body tissues.
What is the endocrine system?
Secrete another form of chemical messengers, hormones, which travel through the bloodstream and affect other tissues including the brain.
What does the thalamus recieve?
Information
Which part of the neuron passes the message through its terminal branches to other neurons or to muscles or glands?
Axon
Which neurotran effects mood, hunger, sleep and arousal?
Serotonin
What makes up the central nervous system?
The brain and spinal cord.
How are the endocrine and nervous system similar?
Both produce molecules that act on receptors elsewhere.
What is the cerebellum?
Enables nonverbal learning and skill memory.
What happens to the Myelin Sheath over time?
Communication to the muscle slows down and eventually leading to zero muscle control.
Agonist does what? Antagonist does what?
Agonist increases neurotransmitters action. Antagonist decreases neurotransmitters action.
What is the peripheral nervous system responsible for?
Gathering information and for transmitting CNS decisions to other body parts.
True or false Can some neural transmitters be chemically identical to hormones?
True
What brain structure has to do with fight or flight?
Amygdala
