brain Flashcards
whats cerebellum for
motor learning, cognitive function, balance
frontal association cortex
intelligence, personality, behavious, mood, cognitive function
parietal association cortex
spatial skills, 3D recognition (shapes, faces, concepts, abstract perception)
temporal association cortex
memory, mood, aggression, intelligence
what is in precentral gyrus
primary motor cortex (contains large motor neurons in periphery to activate movements at periphery)
what language areas only occur in dominant hemisphere
exners area (controls hand for writing
brocas speech area
wernickes area
smagla and agla
what does primary auditory cortex do
organise tones and times (block out unmeaningful context)
what does Wernickes area do
secondary cortical (interprets sounds)
what is in postcentral gyrus
primary sensory cortex (sensory axons recieve info so is granular shaped)
whats aphasia
difficulty in language due to lesion in wernickes area (fluent or sensory aphasia)
whats brocas aphasia
non fluent or motor aphasia (difficulty in expressing what they want to say)
whats connectional aphasia
connection between brocas and wernickes area affected
3 layers that protect spinal cord
pia, arachnoid, dura mater
what do rootlets do
distribute information to and from spinal cord. rootlets come together to form dorsal and ventral root
what do dorsal and ventral root form
spinal nerve
how fast are myelinated and unmyelinated axons
50m/s and 1 m/s
