Unit 7 brain function

gyri

“ridges” that increase surface area of cerebral cortex

sulci

“grooves” that increase surface area of cerebral cortex

cerebral hemispheres

left and right side that help with consciousness, awareness, perception, memory, thought, and initiation of voluntary movements

corpus callosum

white matter connection between right and left cerebral hemispheres

thalamus

sensory integration

hypothalamus

hormone (endocrine) control and homeostasis

midbrain

visual and auditory reflexes

pons

homeostatsis

medulla oblongata

regulates breathing

cerebellum

coordinates movement and balance

frontal lobe

memory, cognition, decision making

parietal lobe

somatosensory processing and body awareness

temporal lobe

auditory processing

occipital lobe

visual processing

lateral ventricle

main source and reservoir of cerebral spinal fluid

white matter

carries action potentials over distance along bundles of axons. connectors

gray matter

processes information with somas, dendrites, and short axons. primarily cell bodies, and processing centers

cerebrum

higher order functions

spinal cord

connects CNS to PNS

pituitary gland

hormone production

optic nerve

transmits information from retina to brain

optic chasm

portion where optic nerves cross to allow visual information from the eyes to be processed by both hemispheres of brain

olfactory blubs

receive information about smells from nose and sends to brain
