Document Summary

Individual cells responsible for receiving and sending information. Cells in the nervous system providing support to neurons i. e glue. Special part of the neuron that receives information. Axon long, thin fibre that transmits signals away from the soma to other neurons, muslces or glands. Insulating material, derived from glial cells + encases axons. Junction where info is transmitted from one neuron to another. The resting potential of a neuron is its stable. A neuron"s stable, negative charge when the cell is inactive. A brief shift in a neuron"s electrical charge that travels along an axon. The minimum length of time after an action potential during which another action potential cannot begin. A microscopic gap between the terminal button of one neuron and the cell membrane of another neuron. Chemicals that transmit information from one neuron to another. A voltage change at a receptor site on a postsynaptic cell membrane.
