Document Summary

Combine scans of atoms responding to magnetic pulse fmri- function via. Soma contains biochemical structures needed to keep the neuron alive, as well as genetic info. Axon transmits signals to other neurons dendrites, muscles or glands. Dendrites collect signals from adjacent neurons and send them to cell body. Terminal buttons / axon terminals small knobs at the end of the axon that release the neurotransmitters. Fatty, white insulation layer that surrounds axon and allows for high conduction speeds by skipping from the nodes of ranvier. In certain circumstances enough graded potentials can equal and action potential: describe the phases in the action potential cycle of a neuron (from resting potential to action potential and back to resting potential). Repolarization: na+ channels close, k+ leaves cell to restore resting potential. Hyperpolarization: a brief refractory period occurs where the neurons membrane is less than -70 mv and cannot fire.
