We use our inner ear to balance using a form of ‘touch’ I guess you could say but why do we always say ‘Lost my SENSE of balance…’
Why isn’t balance our sixth sense? Can balance be classed as a sense or is it a combination of touch (using those little feeling hairs in our inner ear) and sight (to give us a reference as to where we are)?
IIRC, the consensus was that balance is an extension of the sense of touch. The fluid in the ears’ semicircular canals activates nerve cells similar to our skin’s touch cells.
If it were a separate sense, the sence of heat, cold, pressure, and pain could all be segregated as well.
Wrong thinking is punished, right thinking is just as swiftly rewarded. You’ll find it an effective combination.
Remember when you were a kid and you used to spin round and round until you fell over? (Well, I used to do it.) Try it today and see if you think balance should be lumped together with touch!
The division of the senses into five groups is rather arbitrary. Balance using the inner ear can be grouped with touch, balance using the eyes could be grouped with sight (that’s what ice skaters have to use when spinning) but really it’s up to you.
And, if your inner ear is truly gone, there are things you cannot do because you’ve lost them.
All senses are an interface between the central nervous system and the physical world. Each one has a point where mechanical stimulus is converted to nervous signal. Pain is a sense, proprioception (muscle) is a sense, balance is a sense. If you’re going to call balance a form of touch, you might as well call them all a form of touch. The concept of 5 senses is an anachronism from the early days of physiology, the fact that we combine imput between taste and smell doesn’t lead people to declare that they’re not both senses.
Balance is normally achieved by integrating sight, inner ear inputs, and touch (proprioception ?). It can be accomplished by ignoring all but the visual inputs as is done in instrument flight or by relying on the remaining senses (c.f. handy’s post above).

I’m impressed, I had no idea that you had to balance without your inner ears. Was it hard to learn ? I wonder how you would do as an astronaut ? It would be interesting to see how well you would take to instrument flying without your ears to confuse you.
Yes, Oblio, the word proprioception is correct. One of the essays in The Man Who Mistook His Wife For a Hat is about a woman (IIRC) who has no proprioception. She looks directly at her feet while walking, and gets along okay. But if she quits paying attention to a limb, it might end up in some weird position, since it doesn’t feed any information about its position back to the brain.
Hopefully, I can convince you to accept “hopefully” as a disjunct adverb.
Frankly, I would be lying if I said I were confident.
Perhaps this subject is simply too complex for me to explain.
Unfortunately, I would be lucky to explain my way out of a paper bag.
Assuming we are not limiting this to humans, birds have two very interesting kinds of receptors.
Grandry’s corpuscles are found in the tongue and buccal cavities of many species that locate their prey by touch, such as wood storks and woodcocks. They are found only in birds, and exactly what it is they detect is unclear.
Herbst’s corpuscles are found in many birds and are believed to be vibration receptors. The herbst’s corpuscles in the feet and tibia of birds account for the extreme and well documented sensitivity to distant explosions — the birds sense the vibrations carried along the ground.
I suggest you read the article TOUCH in the book The Audubon Society Encylcopedia to North American Birds by John K. Terres, published by Wings Books, a division of Random House Value Publishing, Inc.
