Cerebrum
Outermost part of the brain split into hemispheres, lobes
Frontal Lobe
Higher intellectual functions, awareness of environment personality, verbal communication, voluntary motor control
Parietal Lobe
Sensory interpretation, speech, expression of thoughts and emotions
Temporal Lobe
Auditory and olfactory sensations, understanding speech
Occipital Lobe
Visual stimuli, eye focusing
Insula
Interpretation of taste and memory
Corpus Callosum
Communication between the two hemispheres of the brain
Lateral Ventricles
Circulate nutrients and CSF, cushioning for the brain
Olfactory Bulb
Recognizing and parsing out odors
Diencephalon
Consists of the thalamuses; relays sensory information between brain regions and controls many autonomic functions of the PNS

Links 3rd and 4th ventricle
Pons
Relays signals from forebrain to cerebellum and other autonomic functions
Medulla Oblongota
Continuous with brain stem; breathing, heart and vessels, digestion, sneezing, swallowing
Cerebellum
Receives information from the sensory systems, spinal cord, and other parts of the brain that regulate motor movements
Arbor Vitae
