Brain and Cranial Nerves

Foramen of Monro

Terminology

• Hemispheres• Gyrus (Gyri)• Sulcus (Sulci)• Longitudinal Fissure• Ventricles• CSF

Anatomy of the Brain

• Cerebrum • Cerebellum• Diencephalon• Thalamus• Hyothalamus

• Brain Stem• Midbrain• Pons• Medulla oblongata

Cerebrum

• Anatomy• Frontal lobe• Parietal lobe• Occipital lobe• Precentral gyrus• Postcentral gyrus

• Functions• Sensory cortex• Motor cortex• Emotion• Intellectual processes• Auditory• Visual• Speech

Cerebellum

• Anatomy• Hemispheres

• Functions• Compares intended movement with what is actually happening• Smooth, coordinated movements• Posture/balance

Brain Stem

• Anatomy• Medulla oblongata• Pons• Midbrain

• Functions• Medulla

• Relays motor and sensory information• Regulates heartbeat, breathing and blood vessel dilation

• Pons• Control breathing

Protective Coverings(Meninges)• Dura mater Dense connective tissue

• Arachnoid Nonvascular connective tissue

• Pia mater Highly vascular Covers surface of the brain and spinal cord and invaginates along cortical surface

to form perivascular spaces
