1. Do Now Give three examples of involuntary processes in the human body.

2. Autonomic Nervous System

3. Review 3 types of muscle cells Parts of a neuron

4. Review: Human Nervous System 2 Parts: – C______ Nervous System – P______ Nervous System __________ Nervous System – Sympathetic Division – Parasympathetic Division

5. Somatic Peripheral Nervous System Voluntary movement – Conscious control Skeletal muscle Autonomic Peripheral Nervous System Involuntary movement – Not under conscious control Smooth Muscle Cardiac Muscle

6. Divisions of Autonomic Nervous System Parasympathetic Sympathetic Serve the same organs (except skin, some glands) Divisions work together and balance out

7. Parasympathetic “Rest and Digest” system Normal body maintenance and function Craniosacral system – Brain stem (medulla oblongata), sacral region of spinal cord Internal organs

8. Sympathetic “Fight or Flight” system Thoracolumbar system Controls ALL parts of the body – Skin, sweat, pupils, hair, blood vessels, heart rate, breathing, etc.

9. Exit Ticket Write the following question and your answer on the sheet with your Do Now. Thinking ahead: Since the parasympathetic and sympathetic divisions of the nervous system serve (mostly) the same organs, how can their opposite effects be explained?

10. What’s Next? Anatomy and physiology of the spinal cord, muscles, organs involved in autonomic nervous system Propagation of an action potential down a neuron, pre and postganglionic Neurotransmitters Reflexes Regulation of somatic and autonomic nervous system Nervous System Disorders
