Lab on Da Brain Flashcards
What type of nerve cord is a chordate
dorsal and tubular
What are the 3 bulges that the brain starts as
forebrain
midbrain
hindbrain
what does the forebrain develop into
cerebrum
and
Diencephalon (thalamus/hypo)
what does the midbrain develop into
mesencephalon?
what does the hindbrain develop into
cerbellum
pons
medulla oblongata
what is the cerebrum responsible for
consciousness, memories, reasoning, etc
what does the longitudinal fissure do
its a deep grovve that splits the brain into the right and left cerebral hemispheres
what is the right hemisphere primarily for
the right NOW,
spacially pictures
what is the left hemispere primarily for
past/future
language, words, speech
what are gyri
lumps/hills
what are sulci
indentations/ grooves
what are the main two sulci
central sulcus and lateral sulcus
what is the function of the frontal lobe
thought processing, memory, motor control of speech
what is the precentral gyrus in
the frontal lobe
what does the precentral gyrus do
it is a primary motor cortex that initiates skeletal muscle activity
parietal lobe main function
to make sense of senses,
puts incoming info together for a fuller experience
where is the postcentral gyrus
in the parietal lobe
what does the postcentral gyrus do
is the primary sensroy association area
what are the 4 lobes
frontal, parietal, occipital, temporal
occipital lobe function
visual processsing
temperal lobe function
auditory procession
what is in the corpus callosum
myelinated axons
what does the corpus callosum do
it allows relay between the 2 hemispheres
what does grey matter have vs white matter
grey has cell bodies
white has myelinated axons
