Human Brain Divisions - ANSWERcerebrum, brainstem, diencephalon, cerebellum
What protects the brain? - ANSWERskull, meninges, and BBB
Ventricles of the brain - ANSWERcavities within the brain filled with cerebrospinal fluid; 2 lateral, 3rd
ventricle, 4th ventricle
Meninges - ANSWER3 layers of connective tissue that cover and protect the CNS organs and enclose
CSF.
Dura Mater - ANSWERthick, outermost layer of the meninges surrounding and protecting the brain and
spinal cord
pia mater - ANSWERthe delicate innermost membrane enveloping the brain and spinal cord.
CSF - ANSWERspecial fluid formed in walls of ventricles from blood plasma by permeating through the
choroid plexus; cushions the brain and spinal cord by providing buoyancy, allowing the brain to float.
BBB - ANSWERdiffusion barrier that prevents most particles from entering CNS tissue; brain and spinal
cord separate from general blood circulation. Formed by impermeable brain capillaries, due to astrocytes
due to need for stable chemical environment.
Cerebrum - ANSWERlargest part of the brain, 83%; includes median longitudinal fissure, left and right
cerebral hemispheres, gyri, sulci, and fissures
, corpus callosum - ANSWERA bridge of white nerve fibers that connect cerebral hemispheres
Cerebral cortex - ANSWERouter region of the cerebrum, containing sheets of nerve cells; gray matter of
the brain
Deep sulci - ANSWERfrontal, parietal, temporal, occipital
Frontal sulci - ANSWERcontrols higher level executive fx like reasoning and decision making; controls
motor fx and control over voluntary muscle actions
parietal lobe - ANSWERA region of the cerebral cortex whose functions include processing information
about touch; receive sensory info from receptors in mouth for taste and in skn four touch, pain, and
pressure.
Occipital - ANSWERinterprets visual input
Temporal - ANSWERsensory areas for hearing and smelling
Association areas - ANSWERact mainly to integrate more than 1 type of sensory info for purposeful
action
Primary motor cortex - ANSWERthe section of the frontal lobe responsible for voluntary movement
Primary sensory cortex - ANSWERregions of the cerebral cortex that initially process information from
the senses
Broca's area - ANSWERcontrols language expression - an area, usually in the left frontal lobe, that directs
the muscle movements involved in speech; speech production
