Laboratory 1 Flashcards
What sulcus divides the frontal and parietal lobes?
Central Sulcus
What are the lobes of the cerebral cortex?
Frontal, parietal, temporal, occipital
What divides the frontal and the temporal lobe?
Sylvian Fissure
What separates the parietal lobe from the occipital lobe?
Parieto-occipital sulcus
What are the divisions of the brainstem from rostral to caudal?
Thalamus > Mid Brain > Pons > Medulla > Spinal Cord
What are deep brain nuclei that are involved in motor function and addiction/reward behaviors?
Basal Ganglia
What are the 3 components of the basal ganglia?
Caudate Nucleus, Putamen, Globus Pallidus
What is the term referring to the caudate nucleus and putamen together?
Striatum
What is the term referring to the putamen and globus pallidus together?
Lenticular or lentiform nucleus
What is a deep brain structure that is involved in relaying information between cortex and brainstem and between cortical structures?
Thalamus
What structure forms the walls of the third ventricle?
Thalamus
What is a large white matter bundle that connects the cerebral cortical hemispheres and forms the roof of the lateral ventricles?
Corpus Callosum
What large white matter bundle runs within the diencephalon and connects the brainstem and the cerebral cortex?
Internal Capsule
What is the name of the first coronally orientated gyrus?
Pre-central Gyrus
What structure is immediately caudal to the pre-central gyrus?
Central Sulcus
What is the primary center for voluntary control of motor function?
Pre-central Gyrus
What is the primary center for somatic sensory projections?
Post-central Gyrus
What gyri form the primary cortical centers for hearing?
Transverse gyri (superior surface of temporal lobe)
What carries descending motor fibers to the contra lateral arm and leg, and to the oculomotor nerve as it emerges from the interpeduncular fossa?
Crus Cerebri
An expanding mass in the cerebral hemisphere on one side sometimes causes what to push against the Crus Cerebri resulting in dilation of the ipsilateral pupil and paralysis of the contralateral arm and leg?
Uncus
What are the primary visual receptive areas?
Calcarine fissure and adjacent cortex
What is the cortical matter surrounding the central sulcus on the medial plane?
Para central lobule
What lobe means border, forms the border between the upper end of the brainstem and portions of the cerebral hemispheres?
Limbic lobe
What lobe structures are involved in memory, behavior, emotion, and higher control of visceral functions, and are very Important in behavioral science?
Limbic lobe
The metencephalon is composed of what?
Cerebellum and Pons
What forms the roof of the mecencephalon aka midbrain?
Superior and inferior colliculi
