7 TH SCIENCE RESPONSE TO STIMULI REVIEW
STIMULUS: Anything that causes a reaction
RESPONSE: Reaction caused by internal or external stimuli
INTERNAL STIMULUS: A STIMULUS THAT COMES FROM INSIDE THE BODY OF AN ORGANISM
External stimulus – A signal (stimulus) that originates from outside an organism o Examples:
DEEP CUT = BRAIN PRODUCES ENDORPHINS (NATURAL PAIN KILLER)
DEVELOPING A FEVER DUE TO AN ILLNESS OR INFECTION IS OUR BODY’S INTERNAL FEEDBACK MECHANISM THAT RESPONDS TO ALLOW US TO MAINTAIN BALANCE.
The Nervous System The information and control system.
Homeostasis And how organisms react to stimuli. In your ISN, write these terms – fill in as we go Homeostasis StimulusResponseFight or Flight (Definitions)
FEEDBACK MECHANISMS & HOMEOSTASIS. HOMEOSTASIS Maintaining the internal environment within a stable range given factors that influence the external environment.
PHYSIOLOGY: HUMAN BODY SYSTEMS. Homeostasis “Keeping things in balance” process by which organisms keep internal conditions relatively constant despite.
Dec 2, 2010“A” Day Objective: Students will make models of the central and peripheral nervous system in order to explain their functions. Warm-up: Fig.
1. Are made up of cells and organisms can be a. Unicellular – one cell; single cell b. Multicellular – many-celled.
Made up of Cells 1. Background Need for materials and energy 5. Reproduction 2. Based on genetic code 3. Grow and Develop 4. Response to environment 6.
HOW THE NERVOUS SYSTEM WORKS Chapter 6 Section 1 Pages
Unit 10 Review: Homeostasis. What is a stimulus?
So what is a living thing? Anything that possesses all of the characteristics of life is called an organism. The characteristics of life are as follows:
28.2 Mechanisms of Homeostasis Sponge (Pg. 36) 1)Hypothesize how these climbers hang on to their body temperature.
Central Nervous System (CNS) Peripheral Nervous System (PNS)
The Nervous System The nervous system receives information about what is happening both inside and outside your body. It also directs the way in which.
Homeostasis and Behavior. Every organism constantly interacts with its environment.
Receives information about environment and what happens inside your body Directs how body responds to information Maintains homeostasis.
Feedback Loops Positive and Negative Feedback Loop Examples.
Nervous System Controls and coordinates your body's activities and helps you sense and respond to changes in your environment.
H OMEOSTASIS Homeostasis is the body’s ability to keep the internal balance of the body stable.
You just experienced homeostasis. Your body was trying to keep you upright by maintaining your balance. Homeostasis is regulated by the nervous system.
Stimulus/Response Internal Stimulus A stimulus that comes from inside your body. EX. hunger pains, emotions, and a full bladder.
Chapter 35-1: Human Body Systems Essential Question: How does the human body maintain homeostasis?
Orientation to Biology. By the end of this class you should understand: The organization of the fields of science Characteristics common to all living.
LivingNon-livingDead Organisms must respond to stimuli appropriately in order to stay alive Stimulus = anything in an organism’s external.
F. Necessary Life Functions - Our organ systems work together to maintain the following functions:
TEK 7.13(13) Organisms and environments. The student knows that a living organism must be able to maintain balance in stable internal conditions in response.
Characteristics of Living things (8) Biology: the study of life Organism: any living thing 1) DNA: all living things have DNA (Deoxyribonucleic acid) in.
Homeostasis Defined: The body’s ability to maintain a relatively stable internal environment Homeo = same Stasis = stand, stay.
Characteristics of Life. Living things Living things.
Feedback and Homeostasis Vocab terms to define: – Feedback mechanism – Dynamic equilibrium – Stimuli – Homeostasis – Pancreas – Insulin – Guard cells Review.
COOPERATION MAKES IT HAPPEN Homeostasis. What is homeostasis? The ability of all living things – plants, animals, even bacteria – to maintain stable internal.
Stimulus & Response Notes Title your page: Stimulus & Response Notes.
Homeostasis – Necessary Life Functions What defines all living organisms? Maintain boundaries Movement Locomotion Movement of substances Responsiveness.
30.1 Organization of the Human Body - Organization of the human body - Homeostasis - Feedback Inhibition.
Stimuli and Response-Notes Your body reacts to your environment because of your NERVOUS SYSTEM.
Stimulus and Response Why animals and plants do what they do OR A fancy way of saying cause and effect in the animal world.
Characteristics of Life Chapter 1.3 Studying Life.
Chapter 35-1/35-2 Essential Question: How does the human body maintain homeostasis? What is the function of the nervous system? How is a nerve impulse.
The Nervous System. What does it do? Is the communication and control system of the body. Receives information. Responds to information. stimulus response.
35-1 Summary. Levels of Organization Chemical Chemical Cellular Cellular Tissue Tissue Organs Organs System Level System Level Organismic Level Organismic.
The Nervous System Health 7 – Mr. Green. Jobs of the Nervous System 1. Gathers information 2. Responds to information 3. Maintains homeostasis.
Introduction to Physiology. Physiology Science of body functions Science of body functions Teleological vs Mechanistic views Teleological vs Mechanistic.
Sponge: Set up Cornell Notes on pg. 15 Topic: Ch. 1 Homeostasis Essential Question: Define Homeostasis and explain its importance to survival Don’t forget.
Regulatory Mechanisms in Animals. Regulatory Pathways Animals need to communication systems to regulate their functions effectively. The two systems which.
OBJ: Given notes, video, activity sheet SWBAT explain the function of the nervous system and the structure and kinds of neurons found in the body with.
