Cerebrum

Gyri

raised folds or ridges on the brains surface

Sulci

shallow grooves between the gyri

Longitudinal cerebral fissure

deep groove that separates the right and left brain hemispheres

Corpus callosum

thick band or nerve fibers connecting the two brain hemispheres

Central sulcus

groove separating the frontal and parietal lobes

Lateral sulcus

groove separating the temporal lobe from the frontal and parietal lobes

Frontal lobe

controls voluntary movement, planning, personality, and decision-making

Parietal lobe

processes touch, pressure, pain, temperature, and spatial awareness

Temporal lobe

processes hearing, memory, and language understanding

Occipital lobe

processes visual info

Cingulate gyrus

involved in emotions, memory, and behavior

Lateral ventricles

two large cavities in the cerebral hemispheres that contain CSF

Interventricular foramen

opening that allows the CSF to flow from the lateral ventricles to the third ventricle

Third ventricle

narrow cavity in the diencephalon that contains CSF

Cerebral aqueduct

narrow passage connecting the third and fourth ventricles

Fourth ventricle

cavity between the brainstem and cerebellum that contain CSF

Central canal

small channel through the spinal cord that contains CSF

Medulla oblongata

Pyramids

two raised areas on the front of the medulla containing motor nnerve fibers that control voluntary movement

Anterior median fissure

deep groove running down the front of the medulla and spinal cord

Olive

oval-shaped bulge on the medulla: helps coordinate movement and motor learning

ascedning

Cuneate fasciculus

Pons

Midbrain
