Neuro overview

first neuro lecture

this plane is analagous to putting on a headband coronal plane
this plane makes a cross section of the body horizontal
this plane goes from front to back saggital
the brain is divided into these three regions cerebrum, cerebellum, brainstem
the brainstem is divided into these categories midbrain, pons, medulla
the cerebrum is divided into... cerebral hemisphere, diencephalon
the diencephalon is divided into.... thalamus, hypothalamus
the cerebral hemisphere is divided into... cerebral cortex, basal ganglia, hippocampus
cerebral cortex divided into... frontal lobe, parietal lobe, occipital lobe, temporal lobe, limbic lobe
basal ganglia divided into... caudate nucleus, lenticular nucleus
the interhemispheric fissure is also known as the... saggital fissure
the lateral fissure is also known as the sylvian fissure
the nervous system forms during development by... folding of the neural tube
CNS develops from the... neural tube
the forebrain develops from the prosencephalon
the prosencephalon is divided into... telencephalon, diencephalon
the midbrain forms from the.... mesencephalon
the hindbrain develops from the... rhombencephalon
the rhombencephalon is divided into... metencephalon, myelencephalon
the cerebral hemispheres form from... telencephalon
the thalamus, hypothalamus, epithalamus develop from... diencephalon
the cerebral peduncles, midbrain tectum and midbrain tegmentum form from... Mesencephalon
the pons and cerebellum derive from... metencephalon
the medulla develops from the... myelencephalon
in this neural tube defect, the fetus is not viable. the cranial and pinal neural tube fail to close. craniorachischisis
in this neural tube defect, there is no brain that forms, and the fetus is not viable anancephaly
this is a viable fetus, but the spinal neural tube fails to close spina bifida
in this condition, the split of the hemispheres of the brain does not occur holoprosencephaly
in this condition, the brain is smooth and there are no gyri or sulci. thought to be due to abnormal migration of neurons during the third and fourth month lissencephaly.
this lobe has the primary motor cortex. it is involved in decision making and working memory. known as the "executive lobe" frontal lobe
this lobe has the frontal somatosensory cortex, and is responsible for math, reasoning, facial analysis, visual area for motion..etc. parietal lobe
this is the primary auditory cortex. responsible for color and facial recogniztion temporal lobe
this lobe is responsible for visual processing occipital lobe
this system is involved in affect, emotion, hypothalamus and autonomic system limbic system
this is sometimes considered a part of the limbic system and is respobsible for taste and pain insula
for somatosensory and motor signal for lower extremity are located on the __________ outside of the brain, while signals for upper extremity are more __________ lateral, midline
what are the six layers of the cerebral cortex 1. molecular layer 2. external granular layer 3. external pyramidal layer 4. internal granular layer 5. internal pyramidal layer 6. polymorphic layer
what are the functions of each layer of the cerebral cortex 1-3: associational connections, 4: afferent connections 5: efferent connections 6: associational connections
this part of the brain is made up of five nuclei that are involved with motor systems, cognitive functions, effective motion basal ganglia
what are the five nuclei of the basal ganglia caudate nucleus, putamen, globus pallidus, subthjalamic nucleus, substantia nigra
the thalamus is divided into..... anterior, medial, lateral, and intralaminar groups of nuclei
the thalamus proivdes a gateway to the.... cerebral cortex
the connections from the thalamus to the cerebral cortex follow defined pathways through the... internal capsule
the anterior fibers of this commisure connect olfactory structures, and the posterior fibers connect the temporal cortex of both sides. anterior commisure
this commisure connects the two sides of rostral midbrain and pretectal area. it is involved in consensual pupillary reflex and coordinating vertical eye movements posterior comissure
this commisure interconnects the two hemispheres of the brain corpus collasum
this part of the corpus collosum interconnects the orbital areas rostrum
this part of the corpus collosum is the main interconnection between the two hemispheres body
this part of the corpus collosum interconnects the prefrontal cortex genu
this part of the corpus collosum interconnects temporal and occipital cortices splenium
the anterior blood supply of the brain comes from..... internal carotid
the posterior blood supply of the brain comes from the... vertebral artery
what are watershed regions of the cerebrum? ACA-MCA, MCA-PCA
the posterior horn develops from this embryological structure alar plate
the anterior horn develops form this embryological structure basal plate
what are the anatomical subdivisions of the cerebellum anterior lobe, posterior lobe, flocculonodular lobe, vermis, medial hemisphere, lateral hemisphere
what are the functional subdivisions of the cerebellum? vestibulocerebellum, spinocerebellum, cerebrocerebellum
infarcts in this artery of the brain are far more common due to the larger territory it covers MCA
sudden occlusion of the internal carotid artery can cause infarct in this watershed region ACA-MCA
