- Touch. Touch is thought to be the first sense that humans develop, according to the Stanford Encyclopedia of Philosophy. Touch consists of several distinct sensations communicated to the brain through specialized neurons in the skin.
- Sight. Sight, or perceiving things through the eyes, is a complex process. First, light reflects off an object to the eye. The transparent outer layer of the eye called the cornea bends the light that passes through the hole of the pupil.
- Hearing. This sense works via the complex labyrinth that is the human ear. Sound is funneled through the external ear and piped into the external auditory canal.
- Smell. Humans may be able to smell over 1 trillion scents, according to researchers. They do this with the olfactory cleft, which is found on the roof of the nasal cavity, next to the "smelling" part of the brain, the olfactory bulb and fossa.

The nervous system must receive and process information about the world outside in order to react, communicate, and keep the body healthy and safe. Much of this information comes through the sensory organs: the eyes, ears, nose, tongue, and skin. Specialized cells and tissues within these organs receive raw stimuli and translate them into signals t...
Skin consists of three major tissue layers: the outer epidermis, middle dermis, and inner hypodermis. Specialized receptor cells within these layers detect tactile sensations and relay signals through peripheral nerves toward the brain. The presence and location of the different types of receptors make certain body parts more sensitive. Merkel cell...
What are all those small bumps on the top of the tongue? Theyre called papillae. Many of them, including circumvallate papillae and fungiform papillae, contain taste buds. When we eat, chemicals from food enter the papillae and reach the taste buds. These chemicals (or tastants) stimulate specialized gustatory cells inside the taste buds, activatin...
- Sight. The sense of vision is one of the strongest senses because we tend to believe more in what we see around us. The eyeball sits in the skull’s orbits, protected by bones and fat.
- Hearing. Hair cells in the ear move in response to specific sound frequencies and allow you to hear things. Music, laughter, and alarm bell all reach the ears as sound waves in the air.
- Touch. Your skin is the primary sensory organ because it covers the whole body and is directly exposed to the environment. Your skin forms the first line of defence when you experience any sort of physical or chemical stress.
- Smell. The sense of smell or olfaction gives the brain information about the odour perceived. Olfactory receptor cells in the nose detect odorants in the surrounding.
Nov 15, 2023 · Cones help us perceive color. Rods help with low-light (night) vision. Both types of receptors send electrical signals to the brain through the optic nerve. The brain transforms those signals into visual images. Hearing: Sounds enter our bodies through our ears. Each outer ear is like a funnel.
Jul 12, 2019 · Explore how your nervous system and sensory organs create your five senses. Learn the details of hearing, touch, sight, taste, and smell. And why your body depends on your senses.
Feb 6, 2024 · The five senses in psychology refer to the sensory systems that allow us to gather information about our surroundings. These senses include sight, hearing, taste, smell, and touch. Each sense plays a crucial role in how we perceive and interact with the world around us.
