PSY 2012 Study Guide - Quiz Guide: Myelin, Neuroglia, Axon Terminal
Document Summary
Portion of the neuron that receives signals (cell phones receiving calls) Portion of the neuron that sends signals; transmitters. The central region of the neuron, contains the nucleus which contains the proteins. Chemical messengers specialized for communication from neuron to neuron. Space between two connecting neurons through which messages are transmitted chemically. A gap into which neurotransmitters are released from the axon terminal. Cell in nervous system that plays a role in the formation of myelin and the blood-brain barrier, responds to injury, remove debris, and enhances learning and memory. Promote new connections among nerve cells and releases chemicals to aid in hearing. Glial cells wrapped around axons that act as insulators the neuron"s signal. Small devices made from wire or find glass tubes to record electrical activity from neurons. Electrical charge difference (-60 millivolts) across the neuronal membrane, when the neuron is not being stimulated or inhibited. Membrane potential necessary to trigger an action potential.
