CNS part 1 Flashcards
6 levels of the brain
- MO
- pons
- midbrain
- diencephalon
- cerebellum
- cerebrum
what relays information to the thalamus and brainstem + regulates HR, BP, and digestion
MO
what connects the cerebellum and brainstem
pons
what processes visual and auditory data + maintains consciousness and alertness + reflexive somatic motor responses
mesencephalon
3 parts of the diencephalon
hypothalamus (connects to pituitary)
thalamus
epithalamus
what contains the hormone secreting pineal gland
epithalamus
the hypothalamus is connected to the pituitary via the
influndibulum
what is the second largest part of the brain
cerebellum
the cerebellum is ___ to the pons
posterior
4 ventricles
ventricles 1 and 2 = lateral ventricles
ventricle 3 and 4
what separates the lateral ventricles
the septum pellucidum
where is ventricle 3 found
diencephalon
where is ventricle 4 found
pons and cerebellum
what connects the lateral ventricles and the third ventricle
intraventricular foframen
what connects the third and fourth ventricle
cerebral aqueduct
main portion of the lateral ventricles are found
in the parietal lobes
anterior horn of the lateral ventricles are in the
frontal lobe
posterior horn extends into
occipital lobe
inferior horn extends into
temporal lobe
fourth ventricle communicates with and eventually becomes the
central canal
what are found in the roof of the fourth ventricle
foramina
- communicate with subarachnoid space
what lines the ventricles
ependymal cells
cranial meninges levels
dura, arachnoid, pia
