Nervous system Flashcards
what is part of the central nervous system
everything inside the skull and spine
what happens if the CNS is damaged
it cant repair itself leading to neurodegeneration
what is part of the peripheral nervous system
everything out of the spine and skull
what happens if the PNS gets damaged
it is able to regrow itself unlike the CNS
the PNS can be seen as afferent and efferent system what does this mean
it can be seen as a system of inputs (afferent) and outputs (efferent)
what movement does the autonomic system control
unconscious movement
what is the parasympathetic system for
rest and digest
what is sensory input for
receptors monitor and take in stimuli which sends info to afferent nerves
what is integration for
processing the information and deciding on what move to perform
what is motor output for
effector organs activated and the decision which was made put into place
what are neurones
electrically excitable cells which communicate to other cells via synapses
what are glial cells
non neuronal cells that maintain homeostasis from myelin and protect for neurons
what are astrocytes
type of glial cell, maintain brain environment, regulate chemicals and blood flow
what are oligodendrocytes
type of glial cells, form myelin sheath on axons in CNS
what are Schwann cells
type of glial cell, allow quick transfer of info
