What is the central nervous system made up of?
brain and spinal cord
what is the peripheral nervous system made up of?
neurons residing outside of the brain and spinal cord
what is grey matter?
neuronal dendrites, cell bodies and astrocytes/microglia
what is white matter?
tracts of myelinated axons
what type of glial cells wrap around axons in the CNS?
oligodendrocytes
,what type of glial cells wrap around axons in the PNS?
Schwann cells
how do axons become myelinated?
cytoplasm is squeezed out of the parts of the glial cells surrounding the axon
what is the cortex of the brain?
outer shell of grey matter
what is the basal nuclei?
collections of grey matter located deep within the brain
what are the 3 areas of the cerebral cortex?
sensory, motor, association
what is the sensory area of the brain?
sensory input translated into perception

parietal lobe
what is the function of the somatic sensory cortex?
sensory information from skin, musculoskeletal system, viscera and taste buds
what are some functions of the basal nuclei?
-social behaviors
-memory and emotion
-choosing the correct action in context
-all sensory and emotional information to guide behavior
