PSYCH NOTES - WEEK 1
Neural conference - The body's information is built from billions of cells called neurons. Human and sentient being brains operate similarly, all have motor, sensory, and partnership areas of the brain. Neuron
Cell material part - Life-support of the cell
Dendrites - Receive messages from other cells
Axon - Sends messages to enclosed space body, organs, muscles, or glands Neural sudden thought - (action potential) The traveling electrical memorable Myelin sheath - Covers axon, helps hasten impulses
Terminal branches of axon - Attaches, forms junctions through other cells Action Potential Properties
Threshold - When the excitatory signals minue the prohibitory signals exceed minimum amount intensity (entrance) the neuron fires action potential. All-or-None Response - Strong motive causes more neurons to fire in greater numbers, but does not affect strength or expedite. (Intensity remains the same throughout the axon) Synapse - Between the axon and dendrite of the receiving neuron, tiny gap is called cleft. Neurotransmitters - Chemicals released thwart the synapse and bind receptors forward the receiving neuron making it performance potential. Reuptake - Neurotransmitters that are released, however not used. They are sucked back up ~ the sake of later use. How Neurotransmitters Influence Us:
Seratonin - involved through mood regulation. (Ex SSRI, keeps seratonin from reuptake.) Dopamine - involved through schizophrenia, Parkinson's disease, etc. (Excess = schizo) ACh - Muscle playing, learning, and memory. Also, Alzheimers in what place neurons deteriorate Norepinephrine - Alertness and arousal. Undersupply leads to melancholy. GABA - Major neurotransmitter. Undersupply linked to seizures, tremors, and indisposition to sleep. Glutamate - Neurotransmitter involved with memory. Oversupply overstimulates brain. Key-Lock - Neurotransmitters engage to receptors of the neuron by precise fit. Agonists - A molecule that excites and mimics receiving neurons. (ex. morphia, block pain) Antagonists - Block neurotransmitters. (ex. inhibits...
