Intro to Neuroscience and Spinal Cord Flashcards
what does the cNS consist of
brain nd spinal cord
what are the parts of the brain which are easily seen from the side
cerebral hemispheres
dicephlon between brain
cerebellum
brainstem
what are the structures of the brian from below
telecephlon - cerebral hemispheres
diecephlon between brain
brainstem fully - midbrain, pons, medulla
what happens at the diencephalon
optic nerves originate from here
how does the nervous system originate
develops from tube which develops into lumps = cephalon and grow into structure
what is the smallest region of the hemispheres
midbrain and diencehplon
what are ventricles filled with
fluid CSF
what re the ventricles f the brain
2 x lateral
third
fourth
are all the ventricles associated with each other
yes
what attaches the lateral ventricles to the 3rd vent
intraventricular foramen
what connects the 3rd and 4th vent
cerebral aqueduct
what is a way of identifying a section of midbrain
small tube running down = aqueduct
what si the thin mem between later vents called
septum pallisidum
what is the corpus collosum
at base of telencephalon
huge white matter
major highway for sides of brain to communicate
what are the parts of the corpus callous
splenium posterior aspect
genue and anterior
fornix connection to thalamus
what are gyri and sulci
gyri - bumps
sulci - valleys
what is the parieto-occipital sulcus
very deep sulcus sep lobes
what i the other deep sulcus
central sulcus
what are the lobes of the brain
temporal parietal occipital frontal insula (hidden in fissure)
what is imp about central sulcus
divides motor and sensory cortex
what are the gyri called for motor and sensory cortex
precetral gyrus - motor
postcentral gyrus - sensory
what is the darker rind of the brain
grey matter
what is grey matter
contains neurons, neutron cell bodies and glial cells
why is the brain folded
to increase SA of grey matter fro thinking
