Nervous Tissue and Physiology Week #11 Flashcards

Neuron glue

blood brain barrier, removes excess K+

Form myelin sheaths surrounds neurons in PNS

Defensive cells in CNS- eats bacteria

Wraps around Axon for protection (the only one not in the CNS)

receptive regions

Impulse generating site

phospholipid bilayer (white)

Spaces between mylein sheath to absorb Na+ and K+

where two neurons come together

beginning of axon (first place for Action potential)

sensory neurons

sensory for vision and smell

multiple neurons, motor neurons, and inter-neurons

collects information sends to brain or spinal chord

create motor outputs

go between sensory and motor neurons

thick outer layer of meninges (tough mother)

creates space for nerves and blood vessels

touches the brain (soft mother)

wall inside corpus callosum

looks like an olive
