they are called receptors.
Sensory (afferent) neurons
Responding to stimuli means reacting to changes in the environment through a specific action or behavior. Organisms detect and interpret stimuli using their senses, which then triggers a response to help them adapt and survive in their surroundings. This process is essential for organisms to interact with their environment and maintain homeostasis.
The characteristic shared by living systems where all organisms respond to stimuli is called "irritability" or "responsiveness." This property allows organisms to detect and react to changes in their environment, which is crucial for survival. This response can manifest in various forms, such as movement, growth, or physiological changes, enabling organisms to adapt to their surroundings.
The sensory receptors that detect change are called mechanoreceptors. These receptors are sensitive to mechanical stimuli such as pressure, vibration, and stretch, allowing the body to detect changes in its environment. Examples of mechanoreceptors include Pacinian corpuscles and Merkel cells.
The function of receptors is to check about the taste,smell,etc. In our human body there are two types of receptors and they are gustatory receptors and olfactory receptors where as gustatory receptors will detect taste and olfactory receptors will detect smell.
Sensory (afferent) neurons
The special cells of the sense organs that receive stimuli from the environment are called receptors. The receptors detect different changes in the surrounding envronment and stimulate the neurons to perform the proper tasks.

The function of receptors is to check about the taste,smell,etc. In our human body there are two types of receptors and they are gustatory receptors and olfactory receptors where as gustatory receptors will detect taste and olfactory receptors will detect smell.
Cells that detect changes are called sensory cells or receptor cells. These specialized cells are equipped with receptors that can sense various stimuli such as light, sound, pressure, temperature, and chemicals. They transmit this information to the central nervous system for processing and response.
Mechanoreceptors detect mechanical stimuli such as pressure, stretch, vibration, and touch. They are sensitive to physical changes in their environment and convert these mechanical stimuli into electrical signals that the nervous system can interpret.
sensory neurons
Sensory neurons are the type of neurons that have the ability to monitor the environment. They are specialized to detect stimuli from the external or internal environment and transmit this information to the brain for processing.
