Cerebrum: (high intellectual functions) 2 hemispheres joined at the bottom by corpus callosum Surface of cerebrum contains neurons and glia that form the cerebral cortex Message for movement and sensation cross to the other side of the brain Divided into lobes: Frontal skills, voluntary movement, speech, intellect, behavior, memory, – intelligence, concentration, temper, personality, eye and head movements, sense of orientation, Broca’s area Temporal visual memory, helps humans recognize objects and people’s faces, assist – humans to remember and understand language, interpret other people’s emotions and reactions Parietal interpret simultaneously, signals received from other areas of the brain such – as vision, hearing, motor, sensory, and memory. A person’s memory, and the new sensory information received, give meanings to objects Occipital receive and process visual information, process and shapes – Cranial Nerves: 12 pair of nerves that originate from the brain Olfactory smell – visual fields and ability to see – Oculomotor eye movements, eyelid opening – Trochlear eye movement – Trigeminal facial sensation – Abducens eye movements – Facial eyelid closing, facial expression, taste sensation – Auditory/vestibular hearing, sense of balance – Glossopharyngeal taste sensation, swallowing – Vagus swallowing, taste sensation – Accessory control of neck and shoulder muscles – Hypoglossal tongue movement –
