1. Chapter 14 The Brain

2. Cerebrum Divided into 2 hemispheres Corpus Callosum joins the 2 hemispheres Cortex- highly folded gray matter, deep grooves in the cortex are called fissures Interior of cerebrum consists of white matter Ventricles- chambers in the brain that are filled with cerebrospinal fluid (CSF), it cushions and supports brain, and transports nutrients, etc.

5. Protection of CNS Bone Meninges (dura mater, arachnoid, and pia mater) CSF

7. Lobes Frontal Lobe- controls skeletal muscle Parietal Lobe- perception of touch, pressure, vibration, pain, temperature, and taste Occipital lobe- perception of visual stimuli Temporal lobe- perception of auditory and olfactory stimuli

9. The Limbic System Establishes emotional state Links conscious functional of cerebral cortex with autonomic functions of the brain stem Memory storage and retrieval Associated with motivation Hippocampus- main structure of this system, important in learning

11. The Diencephalon Integrates conscious and unconscious sensory info and motor commands Pineal Gland- secretes melatonin, which regulates day-night and reproductive cycles Thalamus- relay sensory info. Only passing on only some of the arriving sensory info

12. Hypothalmus coordinates nervous and endocrine activities secretes antidiuretic hormone (ADH), which controls water loss from kidneys Feeding and thirst center Regulation of body temperature Control of circadian rhythms controls autonomic activities of the brain stem

14. Mesencephalon “midbrain” - Processes visual and auditory info and controls reflexes triggered by these stimuli Cerebellum- automatic processing center, maintains balance and equilibrium Pons- connects cerebellum to the brain stem Medulla oblongata- bet. Spine and brain, relays sensory info, regulates automatic functions like heart rate
