brain quiz Flashcards
medulla
regulates breathing, cardiac centre (heart rate & force), vasometer centre (blood pressure), RAS
pons
regulates breathing (along with medulla), contains centres for hearing and balance
cerebellum
subconscious control of all movements, maintains balance, posture
midbrain
reflexes for eye & ear, area of dopamine synthesis, part of motor pathway working with basal nuclei
thalamus
gateway to cerebral cortex, edits sensory information, provides crude awareness
hypothalamus
controls ANS, regulates part of endocrine system, synthesis of hormones, responsible for drives, controls body temperature, part of RAS and limbic system
pineal gland
influenced by light, secretes melatonin
pituitary gland
master endocrine gland of the body, secretes tropic hormones (control activites of other endocrine glands)
limbic system
emotions, pain, pleasure
RAS (reticular activation system)
determines state of alertness and focus
basal nuclei
masses of grey matter deep within each hemisphere; help in unconscious control of voluntary movements
corpus callosum
large commissure connecting hemispheres of the brain, allows communication between right brain and left brain
fornix
tract that connects parts of the limbic system and forms the floor of the lateral ventricles
frontal lobe
thinking, voluntary motor control
parietal lobe
somatosensory (touch, pressure, temperature)
temporal lobe
hearing
occipital lobe
vision
spinal cord
skeletal muscle reflexes
primary somatosensory
precisely localizes light, touch & pressure stimuli
primary visual
receives visual info from the eyes
primary auditory
receives auditory info from the ears
primary motor
located in pre-frontal gyrus, controls individual skeletal muscles, devoted to control of precise muscles in face and hands
frontal eye field
controls movement of the eyes
broca’s
controls muscles in larynx and tongue that produce speech
motor association
controls patterns of skeletal muscle movements
wernicke’s
interprets speech, found in GIA
general interpretative area
between temporal, parietal and occipital lobes; correlates information from sensory areas
prefrontal cortex
abstract thought & consequences of actions
auditory association
interprets sounds
visual association
interprets vision
somatosensory association
deeper interpretation of stimuli received by primary sensory area
left hemisphere
logical, sequential processing of information (ex: math, planning)
right hemisphere
hollistic, “big picture” processing of information (ex: recognizing faces, interpreting body language)
