brain features Flashcards
primary motor cortex function + location
-precentral gyrus (frontal lobe)
-signals to direct movement of the body
prefrontal cortex function + location
-frontal lobe
-personality, intellect, judgment, and reasoning
premotor area location + function
-frontal lobe
-learned, complex motor skills
primary sensory cortex location and function
-postcentral gyrus (parietal lobe)
-receive sensory info (pain temperature, proprioception)
primary auditory cortex location and function
-temporal lobe
-integrating + processing auditory signals
primary visual cortex location and function
-occipital lobe
-receive + integrate visual info
somatosensory area + common integrative area location and function
-parietal lobe
-story of sensory info (texture)
cerebellum function
locomotion, movement, balance
brainstem function
controls autonomic body functions - breathing, heart rate
midbrain function
eye movements, auditory + visual processing
pons function
autonomic control of sleep wake cycle and breathing
medulla function
autonomic control of breathing + heart rate
meninges functions
-protection
-physical stability
-shock absorption for spinal cord
what is within the subarachnoid space
cerebral spinal fluid + cerebral blood vessels
falx cerebri function
separates left and right hemispheres
tentorium cerebelli function
separates occipital lobe from cerebellum
falx cerebelli function
separates cerebellar hemispheres
dural venous sinuses location and function
-form in margins of meningeal folds
-drain venous blood from skull through jugular vein
basal ganglia function
coordinated movement
-initiate movement
-speed + accuracy of movement
-direction of movement
what is gray matter comprised of
neuron cells bodies + dendrites
what is white matter comprised of
white fibres - myelinated axons of neurons
thalamus function
-major relay nuclei for sensory + motor
-relays almost all sensory input to corresponding region of cerebral cortex
-crude touch, pain, temperature, pressure
hypothalamus function
-maintains homeostasis (pituitary gland)
-integrating centre for CNS
-mediates visceral responses to emotional states
medial geniculate of thalamus function
auditory system
lateral geniculate of thalamus function
visual system
ventral posterior nucleus of thalamus function
pain, temperature, touch
ventricular system function
formation + transportation of CSF through brain
what forms CSF in the ventricles
choroid plexus
CSF
