In the nervous system, effectors are parts of the body, such as muscles or glands, that respond to signals from the nervous system by performing a specific action. Receptors detect stimuli, while effectors act on the received instructions to bring about a response. Thus, the correct answer is "effector."

Understanding Effectors
Effectors play a crucial role in the nervous system's communication and response mechanisms.
What are Effectors?
- Effectors are parts of the body that respond to signals sent by the nervous system.
- They can be muscles or glands that perform actions or secrete substances.
Role of Effectors in the Nervous System
- The nervous system transmits signals from sensory receptors to the central nervous system (CNS).
- After processing the information, the CNS sends out instructions to effectors to elicit a response.
- This could involve muscle contraction (movement) or gland secretion (hormonal response).
Examples of Effectors
- Muscles: These are the primary effectors that cause movement. For example, when you touch something hot, your hand reflexively pulls away due to muscle contraction.
- Glands: These can secrete hormones or other substances in reaction to stimuli. An example is the adrenal glands releasing adrenaline during stress.
Conclusion
In summary, option 'B', Effectors, are essential components that carry out the commands of the nervous system, enabling the body to react appropriately to various stimuli. Their function is vital for maintaining homeostasis and facilitating interaction with the environment.
