Document Summary

A tale of 2 cells: the neuron. Incoming message from other neurons: extension of neuron that is the site of the action potential, transmits messages, covered in myelin sheath. Allow for faster transmission by the signal jumping from node to node. Synapse occurs at the end of the axon. Releases neurotransmitters from the axon terminal into the synaptic cleft. Neurotransmitters are taken up at the receptors in the dendrites: the glia. Provide structural support for the brain and protect neurons. Feed neurons, aid in uptake in neurotransmitters. Below: (cid:862)pre(cid:863) = a(cid:374)terior (cid:894)rostral(cid:895) of root. Ex. prefrontal cortex: (cid:862)post(cid:863) = posterior (cid:894)(cid:272)audal(cid:895) of root.

Is folded to increase surface area, which results in more computational power: labels.
