Sensory receptors are specialized cells or structures in the body that detect changes in the environment and convert them into electrical signals that can be interpreted by the brain. These receptors are responsible for detecting various stimuli such as light, sound, touch, taste, and smell.
Effector organs, on the other hand, are organs or tissues in the body that respond to signals from the nervous system by carrying out a specific action. For example, muscles are effector organs that contract in response to signals from the brain, allowing us to move our limbs and perform various physical activities.
Overall, the function of sensory receptors and effector organs is to help the body detect and respond to changes in the environment in order to maintain homeostasis and ensure survival.

Sensory Receptors
- Function: Detect stimuli from the external or internal environment and convert them into electrical signals (nerve impulses).
- Types:
- Exteroreceptors: Respond to external stimuli (e.g., touch, temperature, light, sound)
- Interoreceptors: Respond to internal stimuli (e.g., blood pressure, glucose levels)
- Role in homeostasis: Help maintain a stable internal environment by providing the nervous system with information about the internal and external conditions.
Effector Organs
- Function: Respond to nerve impulses by producing an action.
- Types:
- Muscles: Contract to produce movement
- Glands: Secrete substances (e.g., hormones, enzymes)
Relationship between Sensory Receptors and Effector Organs
Sensory receptors and effector organs work together to maintain homeostasis:
1. Sensory receptors detect a stimulus.
2. Afferent (sensory) neurons transmit the signal to the central nervous system (CNS).
3. The CNS integrates the information and determines an appropriate response.
4. Efferent (motor) neurons carry the response signal to effector organs.
5. Effector organs perform the response.
For example:
- Stimulus: Person touches a hot object.
- Sensory receptor: Thermoreceptors in the skin detect the heat.
- Afferent neurons: Transmit the signal to the spinal cord and brain.
- CNS: Integrates the information and determines that the hand should be withdrawn.
- Efferent neurons: Transmit the signal to muscles in the arm.
- Effector organs (muscles): Contract to withdraw the hand and prevent further damage.
