A sensory neuron is a type of nerve cell that plays a key role in our nervous system by helping us understand the world around us. It collects information from our senses, such as sight, sound, touch, taste, and smell, and sends these signals to the brain to be processed. For example, if you touch something hot, sensory neurons carry the message to your brain, so that you react quickly by pulling your hand away. In GCSE Psychology, understanding sensory neurons is important because they help explain how we perceive and respond to different stimuli in our environment.
