senses
Definition
Senses are the ways that we receive information from the world around us. We have five senses: sight, hearing, smell, taste, and touch.
Each sense has its own special receptors that detect different types of stimuli. For example, the eyes have photoreceptors that detect light, the ears have hair cells that detect sound, the nose has olfactory receptors that detect chemicals, the tongue has taste buds that detect chemicals, and the skin has tactile receptors that detect pressure.
When a receptor is stimulated, it sends a signal to the brain. The brain interprets the signal and creates a perception of the world around us.
The senses are essential for our survival. They allow us to navigate our environment, avoid danger, and interact with others.
In addition to the five traditional senses, there are also other senses that are less well-known. These include the sense of balance, the sense of proprioception (our sense of the position of our body in space), and the sense of pain.
The senses are a complex and fascinating part of our biology. They allow us to experience the world around us in a rich and detailed way.

AQA Science Exam Question and Answer
Question:
Describe the role of sensory organs in human perception, focusing on the process of sensation and perception and how they contribute to our understanding of the surrounding environment.
Answer:
Sensory organs are fundamental to human perception, enabling us to interact with and interpret the world around us. Sensation involves the detection of external stimuli by sensory receptors such as the eyes, ears, nose, skin, and taste buds. These receptors convert various forms of energy, such as light, sound, and chemical signals, into electrical impulses that are transmitted to the brain.
Perception, on the other hand, is the brain's interpretation of these sensory signals, giving rise to our subjective experience of the environment. For example, the eyes detect patterns of light and colour, while the brain processes this information to recognise objects and scenes. Similarly, the ears capture sound waves, and the brain transforms them into meaningful auditory perceptions.
The process of sensation and perception is an intricate interplay between sensory input and cognitive processing. It allows us to navigate and respond to our surroundings, guiding behaviours and decisions. However, perception can also be influenced by factors such as expectations, context, and past experiences, sometimes leading to illusions or biases.
