Document Summary

Lecture 18: nervous system organization: nervous system organization, cnidarians. Simplest animals with nervous systems: echinoderms (sea star) C. b)planarian simple cns, brain, eyespot, ladder type nervous system. C. c) annelid/arthropods more complex, brain, ganglia: vertebrates. Nerves and ganglia: pns: nervous system and lifestyle. Ii) glial cells: types of adult glial cells. Oligodendrocytes and schwann cells are myelinated (like insulation around cells: radial glia. B. b)glial cells in adult develop from radial glia in embryo. B. c) zika has been linked to death of neural progenitor cells like radial cells - microcephaly. Gray matter surrounds white matter white matter is myelinated (a. b. 3) B. a)link between the brain and the rest of the nerve system. Sensory receptors detect stimuli (visual, auditory, etc: nerves. B. d)entire body: two functional components of pns. C. a)afferent (sensory) (arrives to cns): receptors not effectors (c. a. 1) Visceral: you are not aware of like blood pressure (c. a. 2)
