Document Summary

Neurons: nerve cells specialized to communicate with each other. Cell body (soma) center of neuron; builds new cell components (parts) Axons tails of the neuron that spread out from the cell body and transit information. Axons: tail-like extensions that stick out of the cell body. Axon terminal: knob-like structure at the end of the axon, containing synaptic vesicles. Synaptic vesicles: contain the chemical messengers known as neurotransmitters. Produced by cell body, sv"s travel down the axon until bursting at the at, releasing neurotransmitters. Tiny fluid-filled space between neurons including a synaptic cleft. Synaptic cleft: tiny gap into which neurotransmitters are released. Dendrites of nearby neurons pick up the neurotransmitters. Astrocytes: increase reliability of neurotransmission, control blood flow in brain, involved in thought, memory, immune response: oligodendrocytes: promotes new connections among nerve cells, releases chemicals that aid in healing, produce myelin sheath.
