- 2. 1 Be silent & listen 2 Stand 3 Sit Yes PNHS Lets go Let god do the rest
- 4. Living things and their environment
- 5. OBJECTIVES: At the end of the discussion the students can: Identify the parts and function of the nervous system. Show appreciation on the importance of taking good care of the Nervous System. Illustrate how peripheral and central nervous system works.
- 6. The Nervous System It connects all our body parts and transmits signals from one part to another. It is a system of cells, tissues, and organs that regulates the bodys responses to internal and external stimuli. Two major divisions: Central Nervous System (CNS) Peripheral Nervous System (PNS) Function of Nervous INTRODUCTION
- 7. Central Nervous System (CNS) - It serves as the main processing center for the entire nervous system. It consists of two main components, namely the: The Brain The Spinal Cord
- 8. Central Nervous System THE BRAIN - is an organ located within the skull that functions as organizer and distributor of information for the body. It has three main parts: Cerebrum Cerebellum Brain stem
- 9. Central Nervous System THE BRAIN - It is large, found at the upper part of the brain that controls activity and thought. CEREBRUM
- 10. Central Nervous System THE BRAIN - The part under the cerebrum that controls posture, balance, and coordination. CEREBELLUM
- 11. Central Nervous System THE BRAIN - The part that connects the brain to the spinal cord and controls automatic functions such as breathing, digestion, heart rate, and blood pressure. BRAIN STEM
- 12. Central Nervous System THE SPINAL CORD - It serves as a channel for signals between the brain and the rest of the body.
- 13. Peripheral Nervous System (PNS) - It connects the central nervous system to the organs and limbs. It has two main divisions: Somatic Nervous System Autonomic Nervous System
- 14. Peripheral Nervous System. Somatic Nervous System - This system is associated with the voluntary control of body movements. . It has two main parts: Spinal Nerves Cranial Nerves
- 15. Peripheral Nervous System. Somatic Nervous System it is the nerves that carry signals between the spinal cord and the body. Spinal nerves
- 16. Peripheral Nervous System. Somatic Nervous System it is the nerve fibers that carry information into and out of the brain stem. Cranial Nerves
- 17. Peripheral Nervous System. Autonomic Nervous System - This system is associated with the involuntary control of body movements and has two subdivisions: Sympathetic parasympathetic.
- 18. Peripheral Nervous System. Autonomic Nervous System Sympathetic - it is activated when the body is in a dynamic role or stress. (e.g., increased heart rate and breathing, dilation of pupil, sweating, etc.)
- 19. Peripheral Nervous System. Autonomic Nervous System Parasympathetic - it maintains body functions and restores the body to normal or relaxed mode.
- 20. Nervous System Activity 1. Break It Down! Major divisions Main components Main divisions Brain Somatic Nervous System Main Parts Main Parts Subdivisions
- 21. Nervous System. The Nerve Cell - it is the basic unit of nervous system, which is also called neurons. - Neurons are cells with the special ability to carry signals or impulses.
- 22. Nervous System. Activity 2; A Nervous Trip Objective: explain how the body processes are controlled through the nervous system Procedure: 1. divide the class into 2/3 groups and compete with the other groups. 2. Among the members of the group, assign students who will represent the following parts: Brain, Organ, Sensory Neurons, and Motor Neurons. 3. Have the Brain stand at one end of the classroom, and the Organ at the other end near the blackboard. 4. After you choose who will be the brain and organ let the rest become sensory and motor neurons. 5. Refer to the following illustration to see how you will position yourselves in the game.
