Document Summary

Neurons: individual cells in nervous system that receive, integrate and transmit information. Soma = cell body: contain cell nuclear and control chemical equipment common to most cells. Dendrites: parts of a neuron that are specialized receive information. Axon: long thin fibre that transmits signals away from soma to other neurons/ parts of body. Myelin sheath: insulation material that covers some axon, derives from glia cells. Gila (glue): cells found throughout the nervous system and provide various support for the. Terminal buttons: small knobs that secrete chemicals called neurotransmitter. Synapse: junction where one information is transmitted to another neuron neurons. Neurotransmitter: the chemical that transmit from one another neuron. The presynaptic neuron (the neuron that send signal send across the synaptic gap) when through the gap and the post synaptic neuron receives the signals. Presynaptic neuron in packed in the synaptic vesicle down to the synapse, release to the gap, the other received end recognized and respond to the information received.
