Brain Flashcards
Cerebrum
- conscious thought process, memory storage, and reasoning
Gyrus
Superficial folds in brain
Precentral gyrus
Last fold in the frontal lobe
Postcentral gyrus
First fold in the parietal lobe
Sulcus
Depression in between the folds
Grey matter
- outside
- forms the cerebral cortex
White matter
- inside
- forms the cerebral medulla
Auditory cortex and association area
Sound
Olfactory cortex and association area
Smell
Wernickes area

Premotor cortex
- assembles muscle movements into correct steps
Primary motor cortex
initiates/controls voluntary movements of body
Frontal eye field
Eye movement

Speech and tongue movement
Corpus callosum
Connects the left and right cerebral hemispheres
Superior Sagittal sinus
Space In the groove of the longitudinal fissure
Choroid plexus
Makes CSF in ventricles
Falx cerebri
Projects into longitudinal fissure and separates left and right cerebral hemispheres
Falx cerebri
Projects into longitudinal fissure and separates left and right cerebral hemispheres
Falx cerebelli
Portion that separates left and right cerebellar hemispheres
Tentorium cerebelli
Horizontal fold that separates cerebrum from cerebellum
Diaphragm sellae
Small septum between pituitary and hypothalamus
Lentiform nucleus
