Chapter 2 - The Brain and Behavior Flashcards
collecting chemical information from nearby structures
Dendrites
information from dendrites is sent to the ____ and if/when it reaches a certain amount of chemical information, it wants to send a signal to another structure
Cell Body
signal is sent down a long tail
- conducts electrical impulses
Axon
axon is covered in ___
- fat blobs used as insulation
Myelin
chemicals will be released out into space and picked up by an adjacent/muscle/gland
Terminal Branches of Axon
houses all the organelles of the cell
Nucleus
channels/windows when ions can flow in or out of the axon through the cell membrane
Nucleus
exchange of sodium and potassium ions which allows a signal to be sent
Nucleus
chemicals released into the space between the axon and the adjacent structure
Synapse
- alzheimers disease (memory)
- agonist: nicotine (muscles, thoughts, behaviors)
- antagonist: botox
Acetylcholine (Neurotransmitter)
- parkisons disease (lose motor movements)
- agonist: schizophrenia (hallucinations, L-dopa)
- antagonist: antipsychotics
Dopamine (Neurotransmitter)
- depression
- agonist: prozac, zoloft (improve mood)
Serotonin (Neurotransmitter)
- anxiety
- agonist: valium, xanax (relaxation)
- antagonist: caffine
GABA (Neurotransmitter)
- depression (body’s natural pain reliver)
- agonist: opiate (addictive)
- narcan (overdoses)
Endorphins (Neurotransmitter)
- fight or flight response
- agonist: epipen
- antagonist: beta blocker (slows heart rate)
Epinephrine (Neurotransmitter)
- ability of your brain to recognize itself
- ex., injuries (stroke)
Neuroplasticity (Neurotransmitter)
brain and spinal cord (center of body)
Central Nervous System
