Flashcards do conjunto (36)
- 1Peripheral Nervous System (PNS)Connects the central nervous system to the body’s organs and muscles
- 2Central Nervous System (CNS)Central: brain and spinal cord->these are composed of interneurons
- 3PNS: Autonomic nervous system (ANS)dual functions: arousal & returning the body to its resting state
- 4PNS: Somatic nervous system (skeletal nervous system)
- 5ANS: Sympathetic Nervous Systemarousing
- 6ANS: Parasympathetic Nervous Systemcalming
- 7Glial Cellsthe pathological sensors of the brain; the glue; ~90% of brain
- 8Glial Cells: Astrocitesthe babysitters
- 9Glial Cells: Oligodendrocytesinsulators of the CNS
- 10Glial Cells: Schwann Cellsinsulators of the PNS
- 11Glial Cells: MicrogliaThe CNS’ “Immune System”
- 12Sensory NeuronsBring in incoming information
- 13InterneuronsConnect and process information
- 14Motor NeuronsAttach to muscle fibers
- 15The Neuron: Cell Body (Soma)nucleus with chromosomes
- 16The Neuron: Dendritesreceive information from other neurons
- 17The Neuron: Axontransmits information to other neurons, muscles, and glands
- 18The SynapseJunction between one neuron’s axon and another’s dendrites/cell body;Neurotransmitters cross the synapse;Plays a fundamental role in the communication between neurons
- 19MyelinInsulating layer of fatty material; Composed of glial cells Helps efficient transmission of signals to other cells
- 20Myelin: nodes of RanvierGaps in myelin sheath
- 21The Action Potential
- 22The Resting PotentialHigher conc K+ inside neuron & higher conc Na+ outside neuron
- 23Na+/K+ Pumprestores resting state charge
- 24The Refractory Periodtime following an action potential; Another action potential can’t occur during the refractory period
- 25Excitatory MessagesProduce Excitatory PostSynaptic Potentials (EPSPs)
- 26Inhibitory MessagesProduce Inhibitory Post-Synaptic Potentials (IPSPs)
- 27Neurotransmitterschemicals that transmit information across the synaptic gap (cleft)
- 28Anatomy of the Synapse
- 29What happens to neurotransmitters in the synapse: ReuptakeNeurotransmitters are absorbed back into the presynaptic neuron
- 30What happens to neurotransmitters in the synapse: Enzyme Deactivation (Disassembly)Neurotransmitters are broken down by enzymes in the synapse
- 31What happens to neurotransmitters in the synapse: AutoreceptorsNeurotransmitters bind to autoreceptor sites on the presynaptic neuron
- 32Neurotransmitter: Acetylcholine (ACh)Functions Malfunctions
- 33Neurotransmitter: DopamineFunctions Malfunctions
- 34Neurotransmitter: SerotoninFunctions Malfunctions
- 35Neurotransmitter: NorepinephrineFunctions Malfunctions
- 36Neurotransmitter: EndorphinsFunctions Malfunctions
