Neuvous Systen Flashcards
Microglia
Remove sell to debris by Phagocytosis
Ependymal cells
Wind ventricle and CNS, assists in producing cerebrospinal fluid
Oligodendrocytes
Mylonite the CNS axons, provide structural framework (produces myelin)
Astrocytes
Absorb and recycle neurotransmitters from scar tissue after injury, maintain the blood brain barrier
Neurons
Basic functional unit of nervous system
Carries’s electrical impulses at great speeds
Neuroglia cells
Support neurons
Sensory
Carries info from PNS to CNS
Unipolar
Interneurons
Link between neurons in CNS
Motor
Carries info from CNS to PNS
Effectors
Multipolar
Action potential
Nerve impulse
Resting membrane potential
The membrane potential of a normal cell under homeostatic condition
Repolarization
30 to -70
Depolarization
-70 to 30
Neurotransmitter released from a motor neuron
Multi polar
Synapse
The site of communication between a nerve cell and some other cell; if the other cell is not a neuron
