Stress: Overview

One Health Stress Module

The stress module covers the concepts of the nervous system, the endocrine system, homeostasis, and feedback mechanisms. Students will have the opportunity to guide their own learning through a variety of “learning objects” intended to provide critical thinking about and application of required science standards.

Keywords: axon, brain stem, central nervous system, cerebellum, cerebrum, dendrite, effector, gland, homeostasis, hormone, negative feedback, neuron, peripheral nervous system, positive feedback, reflex, set point, soma, stimulus, synapse

Subject TEKS:

  • 7.12 (B) identify the main functions of the systems of the human organism, including the circulatory, respiratory, skeletal, muscular, digestive, excretory, reproductive, integumentary, nervous, and endocrine systems.
  • 7.13 (A) investigate how organisms respond to external stimuli found in the environment such as phototropism and fight or flight; and (B) describe and relate responses in organisms that may result from internal stimuli such as wilting in plants and fever or vomiting in animals that allow them to maintain balance.


  • MS-LS1-8. Gather and synthesize information that sensory receptors respond to stimuli by sending messages to the brain for immediate behavior or storage as memories.
  • LS1.D: Each sense receptor responds to different inputs (electromagnetic, mechanical, chemical), transmitting them as signals that travel along nerve cells to the brain. The signals are then processed in the brain, resulting in immediate behaviors or memories.

Grade Level: 6th – 8th

Learning Objectives:

  1. Identify the structures of the nervous system
  2. Describe the main functions of the nervous system
  3. Investigate how organisms respond to internal and external stimuli
  4. Identify the structures of the endocrine system
  5. Describe the main functions of the endocrine system
