brain development Flashcards
what are the 3 primary vesicles?
forebrain
midbrain
hindbrain
what are the 5 secondary vesicles?
(in order)
telecephalon
diencephalon
mesencephalon
metencephalon
myelencephalon
what are the telecephalon lobes?
frontal
parietal
temporal
occipital
what is the rhinencephalon known as?
the ‘olfactory system’ / ‘true brain’
what are the parts of the rhinencephalon?
olfactory bulb
medial olfactory stria
lateral olfactory stria
olfactory peduncle
piriform lobe
what parts is the diencephalon divided into?
thalamus
hypothalamus
epi-thalamus
sub-thalamus
what does the thalamus do?
sensory processing
what does the hypothalamus do?
endocrine function
what does the subthalamus do?
motor intergration
what does the epithalamus do?
pineal gland
some endocrine function
what is the mesencephalon divided into?
tectum
tegmentum
cerebral peduncles
what is the mesencephalon responsible for?
vision
hearing
motor control
wakefulness
sleep
what parts belong to the metencephalon?
cerebellum
pons
what does the pons do?
sensory motor relay
what is the cerebellum responsible for?
motor function
what parts belong to the myelencephalon?
medulla
pyramids
what is the medulla responsible for?
respiratory control
cardiac & vasomotor control
physiological reflexes (e.g. sneezing, coughing)
what do the pyramids of the myelencephalon do?
act as a ‘motor neurone highway’
- all motor neurones from the brain are bundled together and sent down the base of the brain stem
