1. Parts of the Brain Presented by: Raechel Davis

2. 6 Main Regions Cerebrum Diencephalon Midbrain Pons Medulla Cerebrellum

4. Formation of the Brain Stem Midbrain, Pons, and Medula are components. Responsible for relaying signals to the Cerebrum and Cerebellum. Involuntary & voluntary actions are produced from these 3 regions.

5. The Medulla Highway between the brain and spinal cord. Various nuclei transmit nerve impulses that control: - heart rate- sneezing - swallowing - blood pressure - constriction and dilation of blood vessels

6. Cerebrum Lower posterior portion. Responds to signals from: muscles, tendons, joints. Controls: skeletal muscle contractions, maintaining coordination, muscle tone, balance, and posture.

7. 2 Parts of the Diencephalon Thalamus Hearing Taste Vision Sensation Wakefulness Voluntary Motor Control Hypothalamus Autonomic nervous system Secretion from glands Heart rate Intestine movement Rage,Aggression Water balance

8. Cerebral Cortex Human consciousness, motor skills, language, imagination are vital functions. Within each hemisphere there are a number of nuclei. The Basal Ganglia and Limbic System contain a number of different nuclei and sub divisions.

9. Cerebral Cortex

10. Components of: Basal Ganglia Caudate nucleus Putamen Globus palidus Sub thalamic nucleus Limbic System Hippocampus Contributes to emotional states such as: fear, anger, rage, pleasure, and sorrow. Also assoc. with learning and memory capabilities.
