PARTS OF THE BRAIN and TYPES OF GLIA Flashcards
What are the four different types of glia?
microglia
astrocytes
ependymal cells
oligodentrocytes/Schwann cells
What is the function of microglia?
for the immune response
What is the function of astrocytes?
to maintain the mircoenvironment and the blood/brain barrier
What is the function of ependymal cells?
to maintain cerebrospinal fluid and the ventricular epithelium
What is the function of oligodendrocytes/Schwann cells and where are each of these located?
both of these ensheath the axon with myelin
the oligodendrocytes are in the CNS and the Schwann cells are in the PNS
What are the 5 parts of the brain?
frontal lobe temporal lobe parietal lobe occipital lobe cerebellum
What is the role of the frontal lobe? Including the prefrontal cortex
behaviour and movement (precentral gyrus)
the prefrontal cortex is responsible for aggression and emotion
What is the role of the temporal lobe?
hearing and memory
What is the role of the parietal lobe?
sensory
What is the role of the occipital lobe?
sight
What is the role of the cerebellum
coordination of sensory and motor information
What are the 7 special senses in the cortex?
primary taste area visual association area visual cortex Wernick's sensory speech area primary auditory area auditory association area Broca's motor speech area
