What is the structure that detects a stimulus in the body called?
Answer and explanation
Correct answer: Receptor
A stimulus is a detectable change in the internal or external environment, such as light, sound, heat, or pressure. A receptor is a specialised cell, tissue, or sense-organ structure that detects this change and starts a nerve impulse. Therefore, option B is correct. An effector produces the response, while a gland or muscle may be an effector rather than the detecting structure.
