What is the difference between a general sense and a sensory sense?

- Taste. Taste, also known as gustation, is the ability to detect chemicals in food, minerals and dangerous substances such as poisons. This detection is performed by sensory organs on the tongue called taste buds.
- Smell. The sense of smell, or olfaction, is closely related to the sense of taste. Chemicals from food or floating in the air are sensed by olfactory receptors in the nose.
- Touch. Touch or somatosensory perception is perceived by activation in neural receptors in the skin. The main sensation comes from pressure applied to these receptors, called mechanoreceptors.
- Hearing. Hearing, also called audition, is the perception of sound. Sound is comprised of vibrations that are perceived by organs inside the ear through mechanoreceptors.
- 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...
Learn how the eyes, ears, nose, tongue, and skin translate stimuli into signals for the brain to interpret as sight, sound, smell, taste, and touch. Explore the anatomy and function of the sensory organs and receptors with 3D models and videos.
Oct 16, 2017 · Learn how humans and many other animals use touch, sight, hearing, smell, and taste to sense the world around them. Find out how each sense works, what happens when it doesn't, and how you can explore them with activities and images.
- Touch. Your skin is the largest organ in the body and is also the primary sensory organ for your sense of touch. The scientific term for touch is mechanoreception.
- Taste. Speaking of food and drink, try to keep your mouth from watering during the discussion of the next sense. Taste (or gustation) allows your brain to receive information about the food you eat.
- Sight. The third sense is sight (also known as vision), and is created by your brain and a pair of sensory organs—your eyes. Vision is often thought of as the strongest of the senses.
- Hearing. The scientific term for hearing is audition. But this kind of audition shouldn’t make you nervous. Hearing is a powerful sense. And one that can bring joy or keep you out of danger.
Learn about the different types of sensory receptors and organs in humans, and how they respond to various stimuli. Explore the basic features, functions, and pathways of the five senses and other sensory systems.
The human body has two basic types of senses, called special senses and general senses. Special senses have specialized sense organs that gather sensory information and change it into nerve impulses.
