Lec 8 Internal Organization of the cerebrum Flashcards
What are the 4 major C shaped structures of the cerebrum?
- lateral ventricle
- caudate nucleus
- fornix
- stria terminalis
Where is the head of the caudate nucleus located?
- lateral to the anterior [frontal] horn of lateral ventricle
- superior to the temporal horn of lateral ventricle
What is the caudate nucleus?
- C shaped structure of cells
- one of 3 structures that make up that basal ganglia
- part of system responsible for voluntary movement
What is the fornix?
- C-shaped fiber bundle
- carries fibers from hippocampus to mammillary bodies + hypothalamus
What two structures make up the striatum?
- caudate nucleus
- putamen
What two structures make up the lenticular nucleus?
- globus pallidus
- putamen
What is the cingulate gyrus?
part of the limbic system
What is the septum pellucidum?
separates lateral ventricles
What is the septal nucleus function?
reward
What is the amygdala
- most anterior structure of temporal lobe
- part of limbic system
What is important about the uncus?
common focus of seizure activity
What is function of hippocampus?
- learning and memory
What forms the fimbrae of the hippocampus?
fornix fibers
Where is the stria terminalis located?
found between caudate nucleus and thalamus
What is function of stria terminalis?
- C shaped
- output of amygdala to hypothalamus
