Third Ventricle Flashcards
Find the following
- motor cortex
- olfactory cortex
- auditory cortex
- visual cortex
- sensory cortex
the third ventricle sits between what structures?
it is in the midline and on either side of it is the thalamus
what connects the 3rd anf 4th ventricles?
aquaduct of sylvius
what connects the lateral ventricles with the 3rd ventricle?
the foramen of monroe
what is the embryological origin of most of the brain?
diencephalon
*not the limbic lobe is at the junction between diencephalon and telencephalon
what are the regions of the lateral ventricles?
anterior horn (frontal lobe)
body (parietal lobe)
posterior horn (occipital lobe)
inferior horn (temporal lobe)
what structure divides the two lateral ventricles?
septum pellucidum
what structure produces CSF?
Choroid plexus
where is the pineal gland located?
it is located just above the superior colliculus - secretes melatonin
the thalamus is grand central station for what type of information?
for all sensory information
the lateral geniculate and medial geniculate bodies are responsible for what?
lateral = visual
medial = auditory
touch and proprioception sensory information decussates where?
decussates in the medulla
pain and temperature information decussates where?
decussates immediately at the spinal cord
describe the sensory homunculus - where does sensory information go?
remember it’s posterior to the central sulcus?
describe the motor homunculus map
anterior to the central sulcus
