5. 1. BRAIN STEM THE LOWEST SECTION OF THE BRAIN WHICH CONNECTS IT TO THE SPINAL CORD IT HAS 3 PARTS: Medulla Pons Midbrain
6. 2. CEREBELLUM IS AT THE BACK OF THE BRAIN STEM AND IS LINKED TO IT BY NERVE TRACTS IT IS CONCERNED WITH THE MAINTENANCE OF POSTURE AND BALANCE, AND THE COORDINATION OF MOVEMENTS
7. 3. CEREBRUM LARGEST PART OF THE BRAIN HAS 2 HEMISPHERES SEPARATED BY A GROOVE IS DIVIDED INTO 4 SECTIONS OR LOBES

10. THALAMUS– CONSISTS OF TWO EGG-SHAPED MASSES OF NERVE TISSUE WHICH RECEIVE MESSAGES FROM THE SENSORY NEURONS AND SEND THEM TO SPECIFIC AREAS IN THE CEREBRUM WHERE THEY ARE INTERPRETED. HYPOTHALAMUS – LIES BETWEEN THE THALAMUS AND THE PITUITARY GLAND

13. Frontal lobe—conscious thought; damage can result in mood changes Parietal lobe—plays important roles in integrating sensory information from various senses, and in the manipulation of objects; portions of the parietal lobe are involved with visuospatial processing Occipital lobe—sense of sight; lesions can produce hallucinations Temporal lobe—senses of smell and sound, as well as processing of complex stimuli like faces and scenes.
15. THE SPINAL CORD Is a part of the CENTRAL NERVOUS SYSTEM. Begins at the base of the skull and extends throughout most of the backbone, or vertebral column
