CNS and Brain Flashcards
Medulla oblongata main function
-Regulates Homeostasis
-Relays information to the thalamus
Pons main function
Bridge connecting cerebellum to the brainstem
Mesencephalon main function
(Midbrain)
-Processing visual and auditory data
-Maintains consciousness
-Reflexive reactions
Diencephalon
Contains other important centres like Epithalamus, Thalamus, hypothalamus
Epithalamus main function
Part of the diencephalon, contains hormone pineal gland, Produces melatonin
Pineal gland
hormone gland within the epithalamus
Thalamus main function
Part of the diencephalon Relays information to cerebrum for processing
Hypothalamus main function
Part of the diencephalon involves emotions, self regulation and contains the pituitary gland
Cerebellum main function
Contains two hemispheres
-Coordination of muscle movements
Cerebrum main function
Part of the telencephalon
-contains conscious thought
-memory
Cerebrum structure
-Two hemispheres separated by longitudinal fissure
-contains sulci (groves)
-contains Gyri (ridges)
Order of matter in the brain
the cerebrum and cerebellum have similar structures of grey matter covering inner white matter
Septum pellucidum
partition that separates the two lateral ventricles (1 and 2)
3rd Ventricle location
In the diencephalon (middle of brain)
4th ventricle location
Between pons and cerebellum (wide and flat)
inter ventricular foramen
Connection between the lateral ventricles and the 3rd ventricle (same on each side)
Cerebral aqueduct
connection between the 3rd and 4th ventricle
anterior horn location
extends to frontal lobe
Posterior horn location
projects back into occipital lobe
Inferior horn location
extends to the temporal lobe
