Question | Answer |
limbic system components | amygdala, hippocampus, cingulate gyrus, hypothalamus, thalamus |
limbic system fcts | emotion, memory, behavior related to sexual fct, appetite, aggression |
amygdala | involved in signalling of emotions such as fear, reward and motivation, involved in social fcts and mating |
hippocampus | involved in storage of long term memories |
cingulate gyrus | involved in attention, cognitive processing, also affects autonomic fcts such as BP and HR |
hypothalamus | regulates hormone production, connects limbic system in the physical expression of emotions, regulates autonomic fct including temp, BP, HR, ion/electrolyte balance, homeostatic mechanisms hunger, thirst. |
thalamus | relay station to the cortex |
dentate gyrus | may be involved in the formation of new memories and regulating happiness |
nucleus accumbens | center involved in reward, pleasure, addiction |
orbitofrontal cortex | part of limbic system, involved in decision making |
mamillary body | involved in formation of memory |
symptoms of cerebellar disorders | ataxia, hypotonia, intention tremors, dysdiadocokinesis, aesthenia,dymsmetria, pendular reflexes, speech disorders/dysarthria |
midbrain cranial nerve associations | CN III, IV |
pons cranial nerve associations | CN V |
pontine/medulla cranial nerve associations | CN VI, VII, VIII |
medulla cranial nerve associations | CN IX,X, XII |
basal ganglia | corpus striatum in cerebral hemispheres,subthalamic nuclei,substantia nigra in midbrain,caudate, putamen, globus pallidus. |
basal ganglia function | regulating/modulating ms tone, smoothness of movements |
extrapyramidal system | made up of cerebellum and basal ganglia, in dz causes a problem with ms tone, or modulation of movement |
basal nucleus of meynart | degredation of this nucleus is thought to be the cause of Alzheimer's dz, base of the frontal lobe just lateral to the optic chiasm |
VPL and VPM | nuclei in the thalamus that send info to the somatosensory cortex from the spinothalamic tracts |
Anterior cerebral artery | supplies medial and superior surfaces of brain and frontal pole |
Middle cerebral artery | sipplies lateral surface of frontal lobe, parietal lobe, and temporal lobe |
posterior inferior cerebellar artery | supplies inferior vermis, central and undersurface of cerebellum, medulla |
Anterior inferior cerebellar artery | supplies anterior and inferior cerebellum, pons and upper medulla |
Superior cerebellar artery | supplies inferolateral and medail surfaces of the temporal lobe, lateral and medial occipital lobe, thalamus and midbrain |
posterior cerebral artery | supplies midbrain, posterior temporal lobe, and occipital lobe. |
superior cerebral veins | drain superolateral surface of brain |
Inferior and superficial middle cerebral veins | drain inferior, inferoposterior and deep aspects of cerebral hemispheres of brain |
great cerebral vein (of Galen) | single midline vein,merges with inferior saggital sinus to form the straight sinus |
superior and inferior cerebellar veins | drain cerebellum |
