Two functions of the neuronStructural units of the nervous system and to transmit electrical impulses from one area of the body to anotherWhat is the CNS made of?Astrocytes, microglia, oligodendrocytes, brain and spinal chordWhat is the PNS made of?Satellite cells and Schwann cellsPurpose of Myelin SheathSurround and protect nerve fiber coreNodes of Ranviergaps in the Myelin Sheath where the axonal membrane is exposed to extracellular spaceMultipolar NeuronBipolar NeuronUnipolar NeuronPurpose of Interneuronsis 99% of the neurons in the body, is the middle man for sensory neurons and motor neuronsCharge during Resting PotentialNegative inside (-), Positive outside (+)Charge during Action PotentialPositive inside (+), Negative outside (-)AcetylcholineA neurotransmitterSignal transmission speed in Myelinated AxonsIs faster because impulses jump between nodesDirection of a nerve impulsefrom dendrite to Axon Terminalregions of the brainGyriBrain BumpsSulciBrain GroovesHypothalamus FunctionsMaintain homeostasis, link between endocrine and nervous system, and provide hormones that start and stopthe production of other hormones.Things that the hypothalamus is responsible forHeart beats, blood pressure, body temperature, sleep, appetite, thirst, (anything involuntary)
