Sensory receptors detect changes in the environment known as stimuli. These receptors are specialized cells that send signals to the brain or spinal cord in response to specific types of stimuli such as light, sound, pressure, or chemical signals.

Receptor cells are specialized cells that detect specific stimuli, such as light, sound, touch, taste, and smell. They convert these stimuli into electrical signals that can be interpreted by the brain, allowing us to perceive our environment and respond to it accordingly.
Normal cells have built-in mechanisms that regulate their growth and division. These mechanisms involve signals from the surrounding environment, as well as internal checkpoints that ensure the cell has the proper conditions to divide. When these signals and checkpoints detect that the cell population is sufficient or conditions are unfavorable, they trigger the cell to stop growing and potentially enter a state of dormancy or programmed cell death.

Flatworms require three key types of cells to respond to stimuli: sensory cells, which detect changes in the environment; motor neurons, which transmit signals to muscles for movement; and interneurons, which process information and relay signals between sensory and motor cells. These interconnected cells enable flatworms to exhibit simple reflexes and coordinated responses to stimuli. This basic nervous system allows them to navigate their environment effectively.

Cancer cells do not respond to the signals that regulate the growth of most cells. such cells called cancer cells divide uncontrollably and form masses of cells called tumors that can damage the surrounding tissues
A major characteristic of living cells is that they respond to various stimuli in their environment, such as changes in temperature, pH, or nutrient availability. This ability to detect and react to external signals is essential for cells to maintain homeostasis and adapt to changing conditions.
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.
Sensory neurons are specialized cells responsible for transmitting sensory information from various parts of the body to the central nervous system (CNS). They detect stimuli from the environment, such as light, sound, touch, taste, and smell, and convert these signals into electrical impulses. These impulses are then processed by the CNS, allowing for perception and response to the surrounding environment. Essentially, sensory neurons play a crucial role in how organisms interact with and perceive their world.
