Document Summary
Lecture 3: neuronal transmission and conduction (chapter 4 and 5) Neuronal conduction transmission involved in communication of the cns. Neuroactive ligands major families that occur naturally in the cns. Two basic types of cells that comprise the cns diff looks and functions: (1) neurons and (2) glial cells. Primarily messengers - main feature to communicate with other cells is due to the axon (the conveyer) Represent the families of cells that receive info and transmit info. Main feature: the axon represents main conducting of neuron. Billions of neuron that comprise the cns, it difficult to estimate how many there are. Involved in scavenging debris and clean up after cell death. Many more glia cells part for the cns than neurons (about 10 to 15 more times than the amount of neurons) Glia form the membrane that surround the bbb - Functions: metabolic support protect blood barrier, myelin sheath on axons.
