Brain and Cranial Nerves-Chapter 16 Flashcards
What are some general functions of the superior levels of the brain?
intellectual thought, imagination, perception, interpretation
What are some general functions of the middle levels of the brain?
primal drives, emotion, and visual/auditor reflexes
What are some general functions of the inferior levels of the brain?
breathing and cardiovascular function
composed of 2 hemispheres, connected by the corpus callosum, falx cerebri separates longitudinally, ridges (gyri) and grooves (sulic and fissures), gray surface with a white interior
cerebrum
connect different parts of the same hemisphere of the cerebrum
association fibers
connect corresponding cerebral hemispheres
commissural fibers
connect cerebrum to lower brain areas
projection fibers
general area of higher intellectual process, motor areas for voluntary movement of skeletal muscles, association areas of concentration, planning, and problem solving
frontal (anterior) lobe
general sensory area, perception of temperature and touch, association areas for understanding speech and use of words
parietal lobe
sensory area for hearing and smell, association area for interpretation of sensory experiences and recalling visual and olfactory senses
temporal lobe
sensory area for vision and association area to integrate visual with other sensory experiences
occipital lobe
integrates autonomic information, awareness of visceral function
insula lobe
visual cortex
occipital lobe
tactile cortex
parietal lobe
auditory cortex
temporal lobe
olfactory cortex
temporal lobe
gustatory cortex
insula lobe
conscious control of skeletal muscles, most are in the frontal lobe
motor areas
learned motor skills, motor speech area, and voluntary movements of the eyes
motor areas of the frontal lobe
somatic motor association area
frontal lobe
somatic sensory association area
parietal lobe
visual association area
occipital lobe
auditory association area
temporal lobe
found in the left frontal lobe, near primary motor cortex, damage leads to Brocha’s aphasia, function is coherent speech production, thought to be more grammar related
Brocha’s area
