what is the median longitudinal fissure

separates left and right hemispheres

what is the function of the corpus callosities

communication between left and right hemispheres

function of frontal lobe

motor function and intellect

what is the insula

a portion of the cerebral cortex folded deep within the lateral sulcus - primary taste cortex

where is the motor homunculus located

pre-central gyrus

where is the sensory homunculus located

postcentral gyrus

function of Broca's area

motor speech

function of Wernicke's area

speech association

what is the most medial part of the motor homunculus

knee

most lateral part of motor homunculus

tongue

most medial part of sensory homunculus

leg

most lateral part of sensory homunculus

tongue

where are the commissural fibres

corpus callosum

function of association fibres

connect one part of the cortex with another

where are association fibres found

cerebral hemispheres

what are projection fibres

fibres that run between cerebral cortex and sub cortical centres

what is the internal capsule

It consists of ascending and descending tracts (motor and sensory) that connect the thalamus and the cerebral cortex

what is the internal capsule made up of

projection fibres to and from cerebral cortex

thalamus

caudate nucleus

lentiform nucleus

blood supply to internal capsule

middle cerebral artery

what is the basal ganglia

a set of subcortical structures that directs intentional movements

what makes up the basal ganglia

caudate nucleus

putamen

globes pallidus i

what is the lentiform nucleus made of

putamen and globus pallidus

function of caudate nucleus and putamen

input regions

- receive input from motor and pre motor cortexes and thalamus

what is the function of globes pallidus and substantia nigra

projects to thalamus to send fibres to motor cortex areas
