These are clusters of gray matter neuron cell bodies buried deep within the white matter of the cerebral hemispheres.
What are nuclei?
100
These are relay stations for olfaction that bulge exteriorly from the floor of the hypothalamus just posterior to the pituitary gland.
What are mammillary bodies?
100
These are fiber tracts connecting the pons with the cerebrum.
What are the cerebral peduncles?
100
This is a small, midline lobe that connects the two lateral hemispheres of the cerebellum.
What is the vermis?
200
This divides the frontal lobe from the parietal lobe.
What is the central sulcus?
200
These are fiber tracts of white matter that connect 2 portions of the same hemisphere.
What are association fibers?
200
This is structure made of two large lobes of gray matter that laterally enclose the third ventricle.
What is the thalamus?
200
These are two superior prominences on the corpora quadrigemina that are visual reflex centers.
What are the superior colliculi?
200
This is the treelike branching of the cerebellar white matter, also known as the “tree of life.”
What is the arbor vitae?
300
This divides the occipital lobe from the parietal lobe.
What is the parieto-occipital lobe?
300
These are fiber tracts of white matter that run from one hemisphere to another.
What are commissures?
300
This is the stalk that the pituitary gland hangs from.
What is the diencephalon?
300
This is the lowest brain stem region.
What is the medulla oblongata?
300
This is an extension of the inner dura mater that separates the two cerebellar hemispheres.
What is the falx cerebelli?
400
This divides the temporal lobe from parietal lobe.
What is the lateral sulcus?
400
This is located at the base of the precentral gyrus just above the lateral sulcus, damage to this area reduces or eliminates the ability to articulate words. It is located in only one hemisphere, usually the left.
What is Broca's area?
400
This is the orifice that connects the third ventricle with the lateral ventricle on the same side.
What is the interventricular foramen?
400
This is a slender canal traveling through the midbrain that connects the third ventricle to the fourth ventricle in the hindbrain.
What is the cerebral aqueduct?
400
This is an extension of the inner dura mater that separates the cerebrum from the cerebellum.
What is the tentorium cerebelli?
500
This is an extension of the inner dura mater that dips into the longitudinal fissure between the cerebral hemispheres to attach to the crista galli of the ethmoid bone.
What is the falx cerebri?
500
This is the major commissure connecting the cerebral hemispheres. It arches above the structures of the diencephalon and roofs over the lateral ventricles.
What is the corpus callosum?
500
This structure is responsible for creating cerebrospinal fluid.
What is the choroid plexus?
500
This is structure made of two large lobes of gray matter that laterally enclose the third ventricle.
What is the thalamus?
500
The cerebellum is located _______ to the brainstem.
