weeeeeeeeeeeeeeeeeeeeeeeeeeeow-
explain the difference in regeneration of neurons in the PNS vs CNS
in the CNS oligodendrocytes are studded with growth-inhibiting proteins therefore a damaged neuron cannot regenerate
in the PNS, Schwann cells actively aid in recovery through a regenerating tube permitting the regrowth of axon filaments
-
what structures would you find at the precommand level?
what is the function?
cerebellum and basal nuclei
controls the outputs of the cerebral cortex
-
what structures would you find at the projection level?
what is the function?
motor cortex and brain stem nuclei
uses descending projection fibers to convey information to lower motor neurons
-
what structures would you find at the segmental level?
what is the function?
spinal cord
reflexes
-
what is a reflex?
what are the two types?
rapid and predictable motor response to a stimulus
intrinsic and learned reflexes
-
what are the components of the reflex arc
Receptor
Sensory Neuron
Integration center
Motor neuron
Effector
