Document Summary
Help maintain the chemical environment of the neurons: nuerons- the individual cells in the nervous sytem that receive, integrate, and transmit info. Insulating material, from glial cells, that encases some neurons. Speeds up transmissiono of info: multiple scleroris due to deterioration of myelin sheath. Terminal buttons small knobs that secrete chemicals called neurotransmitters. At end of axons in clusters. f: synapse point at which neurons connect. Inhibitory psp negative voltage change that decreases the likelihood: reuptake process in which neurotransmitters are sponged up from the synaptic cleft by the presynaptic membrane. Integrating signals: a balancing act: state of a neuron is the weighted balance between excitatory and inhibitory psp"s, neurotransmitters and behavior. Good table 3. 1 common nuerotransmitters and their functions: acetylcholine (ach, only transmitter between motor neurons and voluntary muscles, contribute to attention, arousal, memory, agonist chemical that mimics the action of a neurotransmitter .
