Document Summary
Neurons nerve cells exquisitely specialized for communication with each other. Cell body (soma) central region of neuron. Dendrites branch like extensions for receiving information from other neurons. Listen to other neurons pass it onto the cell body neurons. Axon terminal knoblike structure at the far end of the axon. Axons long-tail like extensions specialized for sending messages to other. Trigger zone an area that"s easily activated. Neurotransmitters chemical messenger that neurons use to communicate with each other. neurotransmitters travel axon terminal. Synapses miniscule fluid-filled space between neurons through which. Synaptic cleft gap into which neurotransmitters are released from the. Glial cells surround the synapse and provide protective scaffolding for neurons keeps neurons in place. Oligodendrocyte promotes new connections among nerve calls. Resting potential no neurotransmitters acting on neuron. Potential difference electrical charge inside versus outside the neuron release of neurotransmitters. Threshold membrane potential necessary to trigger an action potential. Action potential electric impulse that travels down the axon triggering the.
