Bates Chapter 17 Neuro

Bates Chapter 17 Neuro Brain has 4 regions - 1. Cerebrum 2. Diencephalon 3. Brainstem 4. Cerebellum Brain hemisphere - 1. Frontal 2. Parietal 3. Temporal 4. Occipatal Neurons - Interconnecting nerve cells, consisting of cell bodies Axons - Single long fibers conduct impulses to other parts of nervous system Basal Ganglia (deep in brain) - Affects movement Thalamus - Process sensory impulses Hypothalamus - Maintains homeostasis & temperature regulation, HR, BP Affects endocrine system Governs emotional behaviors e.g. anger, sexual drive Hormones act directly on pituitary gland structures in diencephalon Gray matter - Aggregations neuronal cell bodies. Rims surfaces of cerebral hemispheres = forms cerebral cortex White matter - neuronal axons coated w myelin (white color), allow nerve impulses to rapidly travel Consciousness - interactions between intact cerebral hemispheres & reticular activating (arousal) system in (*diencephalon & upper brainstem*) Identify the following... cerebellum occipital lobe parietal lobe corpus callosum frontal lobe midbrain pons medulla - Identify the following... cerebellum occipital lobe wernicke's area
