Neuroanatomy Terms

Amygdala In Temporal Lobe -experience and expression of emotion
Anterior cerebral a. Runs medial - Frontal, parietal, superior temporal
Anterior choroidal a. Blood to the choroid
Anterior commissure bundle of axons, connects cortex - inferior to fornix, lateral ventricle
Anterior inferior cerebellar a. Artery to Cerebellum, splits off basilar artery, just superior to vertebral artery
Anterior spinal a. Supplies ventral and intermediolateral cells, spinothalamic/corticospinal tracts
Basal ganglia Large clusters of cells that modulate thalamic interactions w/ frontal lobe
Insula Between frontal and temporal lobes- visceral/autonomic fx, taste perception
Brainstem Where the spinal cord meets the brain. Highway for sensory/motor neurons. Maintains life-cardiac and respiratory control.
Broca’s area Posterior third of the Left inferior frontal gyrus- language production
Calcarine sulcus sulcus between lingual gyrus and cuneas gyrus
Caudate Basal Ganglia - between internal capsule and ventricle
Central sulcus Separates the Frontal and Parietal Lobes
Cerebellum Control of Movement, Sends error messages when a problem is found
Inferior olives Learning new movements, in rostral medulla
Cerebral aqueduct Connects the 3rd and 4th Ventricles
Cerebral cortex Temporal, Frontal, Parietal and Occipital Lobes
Cerebral hemispheres The brain is separated in half, saggitally. Each half is a hemisphere
Cerebral peduncles Within the midbrain, bundles of axons, including corticobulbar/spinal tracts
Cingulated gyrus Gyrus that surrounds corpus callosum - important in limbic system
Cingulated sulcus Sulcus that surrounds cingulated gyrus - important in limbic system
Circle of Willis Arrangement of the arteries at the base of the brain, from Int Carotid & Basilar
Corpus callosum Contains millions of axons and connects the cortices of the two hemispheres
Cuneate nucleus Part of DCML System- nucleus in caudal medulla - mechanosensory for Arms
Cuneate tract DCML System-tract runs lateral to gracile tract to caudal medulla -mechanosensory for Arms
Diencephalon Thalamus, hypothalamus, mamallary bodies caudal to hypothalamus
Dorsal column Medial Dorsal spinal cord, white matter. Ascending sensory from mechanoreceptors
Dorsal horn Gray matter the recieves sensory info entering via dorsal roots
Dorsal root Where the axons enter the spinal cord, sensory info into spinal cord
Dorsal root ganglion Cell bodies of neurons entering the dorsal root sit here.
Dorsal thalamus No idea how this is different than the thalamus.
Epithalamus Small strip of tissue attached to pineal gland
Forebrain Cerebral hemispheres and diencephalon
Fornix Large bundle of fibers connecting hippocampus with hypothalamus
Fourth ventricle Holds CSF. Cerebral aquaduct attaches it to 3rd ventricle. CSF can exit here
Frontal lobe Most anterior lobe. Commands!
Globus pallidus Basal Ganglia- medial to putamen
Gracile nucleus Part of DCML System- nucleus in caudal medulla - mechanosensory for legs
Gracile tract DCML System-tract runs medial to cuneate tract to caudal medulla -mechanosensory for legs
Hippocampus Limbic System: Long term memory and spatial navigation
Wenickes Area Wernickes is found in the middle temporal gyrus. Understanding language.
White Matter Vs Gray Matter White matter: myelinated axons Grey Matter: Contrains neuronal cell bodies and capillaries
Hypothalamus Controls homeostasis and reproductive functions
Inferior colliculi On the midbrain- Concerned with Audition
Inferior frontal gyrus Most inferior portion of frontal lobe. Contains Brocas area on the Left
