Session 3- Intro to neuroanatomy: general organisation and functional anatomy Flashcards
what makes up the forebrain
cerebrum
dicephalon
what makes up the brainstem
midbrain pons and medulla
what is grey matter made up of
cell bodies
what are fissures
deep dips into the brain
what is white matter
dense packed billions of axons
what are the main sulci
central sulcus
lateral fissure
longitudinal fissure
parietal-occipital sulcus
major function of the brainstem
- number of cranial nerve nuclei are found at different points in the brainstem
- pons= feeding= trigéminal nerve exits here
- medulla= CVS respiratory centre reside here
- many motor and sensory fibres within
function of frontal
voluntary motor control speech production social behaviour impulse control high cognition
function of temporal
language emotion long term memory sense of smell hearing taste
function of parietal
somatosensory perception
spatial awareness
function of occipital
visual perception
function of cerebellum
co ordination and motor learning
pathway of the spinal nerves
pathways connecting primary motor cortex with spinal nerves controlling the limbs cross to the opposite side at the level of the lower medulla
cortical control of limb movement is from one primary motor cortex which is contralateral
pathway of cranial nerves
pathways connecting primary motor cortex with cranial nerves controlling the muscles of face/ neck cross to the opposite side at the level the nuclei onto which they communicate
cortical control of muscles is from one primary motor cortex which is contralateral
most cranial nerves has cortical input from the ipsilateral cortex as a back up
