neurology content quiz 1

CNS

brain structures and spinal cord

PNS

spinal and cranial nerves

somatic

some voluntary control over such as contraction of skeletal muscles

autonomic

dont have control over such as digestion

brainstem

midbrain, pons, medulla

left hemisphere

for most people, most language,/cognition occur here (perisylvian era)

corpus callosum

hemispheres connected by, primary highway

hills

gyrus, gyri

valleys

sulcus, fissure

sylvian fissure

lateral sulcus, in each hemisphere

perisylvian area

area around sylvian fissure

central sulcus

divies frontal lobe from parietal lobe

fronal lobe

brocas area, premotor,motor, pre frontal lobe

brocas area

important for language production, ex.finding right words, organizing syntax

premotor

planning and programming motor sequences for speech production

motor

sends neural signals from the frontal lobe towards the body to produce speech

prefrontal

important for cognition, especially executive functions- planning, reasoning, organizing

parietal lobe

sensory

primary sensory

receives nerve signals about sensation from the body, important for body awareness, perception, where things are in relation to us, helps with language comprehension

temporal lobe

primary auditory, wernickes area, ventral, memory, emotion, social skills and empathy

primary auditory

heschls gyrus- process auditory ignals

wernickes area

language comprehsnion

ventral

neural pathways with visual images help recognize faces and object

occipital

visual processing, where eye send signals

occipital dorsal

on top “where” (spatial info about what you see)

occipital ventral

btotom “what” (recognize what you see)

insula

sits deep in sylvian fissure helps other parts, not a primary player for any one thing
