The Brain Flashcards
Gyrus (gyri)
Convoluted ridges on surface of brain
Sulcus (sulci)
groove in surface of brain.
Provides a larger surface area
Central sulcus
Separates frontal and parietal lobes
Precentral Gyrus
In front of central sulcus
Coordinates motor movement
Postcentral gyrus
Behind central sulcus
Coordinates sensory activity
Frontal Lobes
Function: Motor skills, higher-level thinking, cognitive function
Parietal Lobes
Gives us perspective and helps us understand touch, space, & volume
Temporal Lobes
Need to figure out
Occipital Lobes
Related to vision
Lateral fissure
separates cerebrum & cerebellum
Cerebellum
Voluntary motor movement and balance
Receives input from other areas of brain
Dura Mater
Meninges that cover the brain
Function: Protection
Falx Cerebri
Part of dura mater. Sits in longitudinal fissure between hemispheres
Longitudinal Fissure
Separates two hemispheres on brain
Superior sagittal sinus
Little “hole” looks like a triangle, formed from the falx cerebri
Drains venous blood
Corpus collosum
Band of nerves fibers that separate hemispheres. Help the two sides to communicate
Lateral ventricles
Contain CSF
Septum Pellucidum
Vertical membrane separating left and right lateral horns
Fornix
Connects the hippocampus to the hypothalmus
Thalamus
Regulates sleeping & wakefulness states
