Question | Answer |
---|---|
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 |
