Document Summary

Neurons- the basic building blocks of the nervous system. Dendrites- extend from the cell body, they collect messages from neighboring neurons (connected to 100 neurons) Cell body- (soma) contains biochemical molecules and structures needed to keep the neuron alive. Axon- also communicate with the other neurons with neurotransmitters. The action potential is a sudden reversal in the neuron membrane voltage durng which the membrane voltahe momentarily moves from -70mv to +40mv celled depolarization. How neurons communicate: synaptic transmission synapse- the microscopic spare between neurons order which the nerve impulse is biochemically transmitted. Neurotransmitters they are chemical substances that carry messages across the synapse in. 5 steps synthesis- the chemical molecules formed in the neuron storage- they are stored in synaptic vesicles release- when action potential reaches the axon terminal, they are realeased bind- they attach themselves to receptor proteins deactivation.
