brain structures

gyri

ridges on surface of brain

sulci

depressions (wrinkles) on surface of brain

longitudinal fissure

deep crack between two hemispheres of brain

thalamus

structure in middle of the brain, relays information from left to right hemisphere

hypothalamus

anterior to thalamus. responsible for hunger/thirst sensations and routine involuntary habits

hypophysis

pituitary gland

cerebellum

permits smooth, coordinated muscle movements

occipital lobe

lobe at the posterior of the brain

cingulate gyrus

part of the limbic system. above corpus callosum and responsible for long term memory

corpus callosum

bundle of nerves that allow the two sides of your brain to interact. inferior to the cingulate gyrus and superior to the thalamus

reticular activating system

mainly located in midbrain - keeps you alert

pons

alters heart rate and breathing

medulla oblongata

controls regular, rhythmic heart rate and breathing

choroid plexus

2 locations, produces cerebro spinal fluid

arachnoid granulation

CSF gets into the circulatory system through this structure

genu

anterior curve of corpus callosum

rostrum

pinched, narrow, inferior portion of corpus callosum

splenium

posterior portion of corpus callosum

corpora quadrigemina

posterior portion of the midbrain. contains colliculi

superior colliculus

portion of corpora quadrigemina that responds to vision

inferior colliculus

portion of corpora quadrigemina responds to sounds

fornix

sits on top of the anterior portion of the thalamus

meninges

layers of membranous material that surrounds the brain and Spinal cord. protects nervous system

pia mater

adjacent to surface of brain and spinal cord

arachnoid mater

superior to pia mater

dura mater

lining of inside skull. superior to arachnoid mater
