Description
The “Sense Organs & Reflex Action (70x100cm)” chart is a large-format educational wall poster that provides visual explanations of the structure and function of the five primary sense organs as well as the basic neural pathway of reflex actions. This chart is widely used in biology classrooms and laboratories for teaching the fundamentals of sensory perception and rapid involuntary responses.
Key Features
The poster typically displays labeled diagrams of the five main sense organs: eyes (sight), ears (hearing), nose (smell), tongue (taste), and skin (touch), often showing the organ’s structure and associated sensory receptors.
For each sense organ, it highlights the stimulus detected, the part of the body involved, and the main action (e.g., seeing with the eye, hearing with the ear).
The chart illustrates the biological pathway of a reflex action—commonly known as the reflex arc—which includes stimulus detection at a receptor, transmission through sensory and motor neurons, and instant response by effectors (muscles or glands).
Diagrams of the reflex arc emphasize the components: receptor, sensory neuron, relay neuron/spinal cord, motor neuron, and effector, showing a rapid, automatic, and protective response (such as hand withdrawal from a hot surface).
Educational Use
The large (70x100cm) size makes the diagrams and labels easy to see in group teaching scenarios or presentations.
This chart is ideal for secondary/high school biology or introductory physiology, helping students understand both sensory processing and the basics of neural circuits.
It provides a concise overview that connects real-life experiences (reflexes, sensory input) to underlying anatomical and physiological mechanisms
