Week 3 Flashcards
In general, what is the Central Nervous System
Brain and Spinal chord
In General, what is the peripheral nervous system
connects brain to external and internal environment.
What is the Somatic NS
Connects our sense from external to internal.
What is the Autonomic NS
Monitors and regulates circulation, digestion and respiration. Has two parts, sympathetic NS and parasympathetic NS
What is the sympathetic NS?
Fight or flight (speed)
What is the Parasympathetic NS
Rest and Digest (pillow)
What is the main function of the limbic system
It tells us what we need for survival. It is involved in our behavioral and emotional responses.
What parts of the brain are included in the reward pathway?
VTA, Amygdala, Ventral Pallidum, Hippocampus, Nucleus Accumbens and prefrontal cortex.
Is neurotransmission electrical or chemical in a neuron?
Electrical
Is neurotransmission electrical or chemical in a synapse
chemical
What are neurotransmitters stored in?
sacs called vesicles
What happens when the sacs are released?
They cross the synapse and bind to receptors on the dendrites of the next neuron.
How many neurotransmitters does a nerve cell produce
1
Receptors are designed to receive any neurotransmitters, True or False
False
Dendrites on cell bodies have only 1 type of receptor for 1 type of neurotransmitter, True or False
False, Dendrites on the cell bodies have multiple receptors for different neurotransmitters-But, again, each receptor can only accommodate a specific neurotransmitter
Force
Force the release of neurotransmitters by entering the presynaptic neurons, creating an exaggerated effect
Block
Block neurotransmitter reuptake sites on neuron cell walls, causing them to remain in the synapse and bind to receptors inducing more intense effects
What is an Agonist
binds to a neurotransmitters receptor and mimics or facilitates the effects of a neurotransmitter. Heroin is an opioid agonist
Antagonist
Blocks the effects of the neurotransmitter
naltrexone
Partial agonists
partially mimics the effects of the neurotransmitter.
