First off, a definition of “sense”:
Any system that consists of a group of sensory cell types that respond to a specific physical phenomenon and that corresponds to a particular group of regions within the brain where the signals are received and interpreted.
There is some variance in the number of senses that scientist say that humans have, but there’s complete agreement that it’s more than 5.
Here are some of the senses that we have other than your basic sight, sound, taste, smell, and touch:
- Muscle tension
- Proprioception (the ability to tell where your body parts are, relative to other body parts)
- Equilibrioception (the ability to keep your balance and sense body movement in terms of acceleration and directional changes)
- Stretch Receptors (These are found in such places as the lungs, bladder, stomach, blood vessels, and the gastrointestinal tract.)
- Chemoreceptors (These trigger an area of the medulla in the brain that is involved in detecting blood born hormones and drugs. It also is involved in the vomiting reflex.)
