Nervous System PREPARED BY: Aya Cherry B. Joaquin S10LT - IIIc -36  Describe how the nervous system coordinates and regulates these feedback mechanisms to maintain homeostasis. Learning Objectives  To understand the functions of Nervous system;  To list the structural & functional units of Nervous system  To describe the divisions of Nervous system;  To distinguish sympathetic from parasympathetic Nervous system The Nervous System ❖ Specialized cell that transmits messages to and from the brain to the spinal cord to other parts of the body. 1) Central NS -serves as the main processing center of the nervous system. A) Brain  Part of the Function Bain 1. Cerebrum -responsible for sensing, thinking, emotions, and voluntary movements. 2. Cerebellum -controls balance and fine muscle movement. 3. Brain Stem -controls bodily functions like breathing, circulation, and sleep. 4. Limbic -responsible for basic biological System needs. Four Lobes Frontal Parietal Occipital Temporal Frontal Lobe Responsible for cognitive functions and movement. Parietal Lobe Responsible for processing touch, pain, temperature, and movement. Occipital Lobe Responsible for vision. Temporal Lobe Responsible for speech, hearing, and memory. B) Spinal Cord -an elongated bundle of neurons; channel for signal between the brain and the majority of the body parts. 2) Peripheral NS -connects the central nervous system to the organs and limbs. -also controls reflexes (involuntary muscle response to a stimulus with out the input from the brain. Examples: - Pulling hand back when you touch something hot - Jumping when you hear a loud sound Sympathetic- “fight or flight” response, stimulating the body to use energy. Parasympathetic- tries to conserve energy, doing “Rest or Digest”.  Activity 1: Categorize the following movements if these are somatic or autonomic. (Refer to the DepEd module)  Activity 2: Using the given graphic organizer, fill in the missing parts to complete the entire concept showing the structure of the nervous system. Nervous System HOMEOSTASIS AND THE BODY SYSTEMS HOMEOSTASIS AND THE BODY SYSTEMS  Activity 3: Explain how these systems help in maintaining Homeostasis. Write your answer on a separate sheet of paper.  How Nervous System coordinates and regulates feedback mechanisms to maintain homeostasis? The nervous system provides quick responses in maintaining homeostasis. The nervous system and endocrine system are working together to maintain body’s homeostasis. Homeostasis is maintained in the body by regulating the body temperature, blood pressure, pH, and glucose concentration.
