Humans have a lot more than five senses, here are 9

1. Pressure

Obvious sense is obvious.

2. Itch

Surprisingly, this is a distinct sensor system from other touch-related senses.

3. Thermoception

Ability to sense heat and cold. This also is thought of as more than one sense — not just because of the two hot/cold receptors, but also because there is a completely different type of thermoceptor, in terms of the mechanism for detection, in the brain. These thermoceptors in the brain are used for monitoring internal body temperature.

4. Sound

Detecting vibrations along some medium, such as air or water that is in contact with your ear drums.

5. Smell

Yet another sensor related to a chemical reaction. This sense combines with taste to produce flavors.

6. Proprioception

This sense gives you the ability to tell where your body parts are, relative to other body parts. It’s one of the things police officers test when they pull someone over who they think is driving drunk. The “close your eyes and touch your nose” test is testing this sense.

This sense is used all the time in little ways, such as when you scratch an itch on your foot, but never once look at your foot to see where your hand is relative to your foot.

7. Tension sensors

These are found in your muscles and allow the brain the ability to monitor muscle tension.

8. Nociception

In a word, pain. This was previously considered the result of overloading other senses, such as touch. But now it’s viewed as its own unique sensory system. There are three distinct types of pain receptors: cutaneous (skin), somatic (bones and joints), and visceral (body organs).

9. Equilibrioception

The sense that allows you to keep your balance and sense body movement in terms of acceleration and directional changes. This sense also allows for perceiving gravity.

This sensory system is found in your inner ears and is called the vestibular labyrinthine system. Anyone who’s ever had this sense go out on them knows how important it is. When it’s not working or malfunctioning, you literally can’t tell up from down. Moving from one location to another without aid is nearly impossible.
