Neuroanatomy Flashcards
describe the development of the brain and CNS
the notochord in the mesoderm secretes hormones which induces the overlying ectoderm to invaginate and form the neural tube which will become the brain and CNS
where do the nerve fibres cross over
medullary pyramid
true or false: all of the brain has control over the contralateral side
false - the cerebellum has ipsilateral control
what are sulci
the grooves in the cerebral hemispheres
what are gyri
the folds in the cerebral hemispheres
what are the ventricles in the Brain filled with
CSF
why do the ventricles appear dark on a CT
as they are filled with fluid
what is the frontal lobe responsible for
motor function and speech
what is the parietal lobe responsible for
sensation, spatial awareness
what is the temporal lobe responsible for
memory, smell and hearing
what is the occipital lobe responsible for
vision
what is the cerebellum responsible for
fine motor control and balance
what connected the 2 hemispheres of the brain
corpus callosum
what is the brainstem made up of
midbrain, pons and medulla
what is the midbrain responsible for
eye movements and reflexes to sound and vision
