Question | Answer |
---|---|
middle of three layers (meninges) surrounding the brain and spinal cord | arachnoid mater |
part of the brain that controls balance and muscle coordination; located inferior to the cerebrum | cerebellum |
channel connecting the third and fourth ventricles and containing CSF | cerebral aquaduct |
network of capillaries located in the roof of ventricles; contributes to production of CSF | Choroids Plexus |
large band of nervous tissue that connects the two cerebral hemispheres | corpus callosum |
outer portion of cerebrum | cortex |
region of the brain made up of the thalamus and hypothalamus | diencephalon |
tough connective tissue layer that serves as the outer layer of the meninges | dura mater |
areas of the brain and spinal cord containing cell bodies, dendrites, and unmyelinated axons; found in the cerebral cortex of the brain and inner portion of the spinal cord | gray matter |
folds of the cerebral cortex | gyri |
a region below the lateral ventricles; involved with emotional states and converting short term memory to long-term memory | hippocampus |
pituitary gland; controls a number of endocrine glands | hypophysis |
part of the diencephalon; inferior to the thalamus and responsible for regulation and maintenance of internal homeostasis by controlling body temp, appetite, fluid balance, etc. | hypothalamus |
the most inferior portion of the brain stem; contains centers for heart rate, blood pressure, and respiration. Also contains reflex centers controlling coughing, sneezing, hiccuping, etc. | medulla |
the part of the brain between the pons and diencephalon | midbrain |
contains cell bodies of neurons that synapse with neurons of the olfactory nerves | olfactory bulb |
crossing point of the optic nerves | optic chiasma |
innermost of the meninges layers | pia mater |
endocrine gland located in the roof of the third ventricle; secretes melatonin | pineal body |
anterior to the medulla; contains nerve tracts that connect the cerebellum with other parts of the brain and spinal cord | pons |
grooves between gyri of the brain | sulci |
part of the diencephalon, superior to hypothalamus; serves as a sensory relay center. | thalamus |
one of four cavities in the brain filled with CSF | ventricle |
bundles of myelinated axons within the brain and spinal cord; found in the inner portions of the cerebrum and outer regions of the spinal cord | white matter |
