Brain anatomy Flashcards
(18 cards)
Ventricular foramina
Allows lateral ventricles to communicate with third ventricle
Cerebral Aqueduct
Connects third + fourth ventricles
4 nuclei of cerebellum
” Dentate nucleus
“ Globose nucleus
“ Emboliform Nucleus
“ Fastigial Nucleus
4 nuclei of basal ganglia
” Caudate nucleus +
“ Lentiform nucleus- Putamen, Globus pallidus
“ Subthalamic nucleus
“ Substantia nigra
Types of fibres in brain
Association fibres
Commissural fibres
Projection fibres
4 nuclei of the cerebellum
Denate nucleus
Globose nucleus
Emboliform nucleus
Fastigial nuclues
What does the diencephalon contain
thalamus - epi/hypo + third ventricle
thalamus
directs sensory info way cerebral cortex. Motor involvement basal ganglia + cerebellum. Interconnected limbic
Functional division limbic system
Eating Fighting Sex Enjoyment Fear memory formation recall Autonomic preparation
Structural div limbic system
Amygdala - emotions + drives
Hypothalamus- motivation + hoemostasis
Olfactory cortex -olfaction
Memory formation - hippocampus
Supraoptic nucleus
ADH vassopressin
Paraventricular nucleus
Oxytocin
Fornix
connects hip with mam bodies
hippocampus
memory consolidation + learning. Temporal lobe info sensory association areas
Amgdala
recognize fear others, emotional compoent fear and memory - connections cortical association areas * intergration perception + emotion. Output hypo via stria terminalis.
olofactory nerve
bi-polar neurons, no thalamic relay no ganglion formed
association cortexs
Prefrontal, inferior temporal, parietal temporal + occipital
combine different modalities - deal external stim or internal motivation + identify sig.
Alzeihmers
degen disease cortex
First affects hippo -> anterograde amnesi
