Wikipedia’s section of other senses under the Percention section, suggests the following:
Other senses enable perception of body balance, acceleration, gravity, position of body parts, temperature, pain, time, and perception of internal senses such as suffocation, gag reflex, intestinal distension, fullness of rectum and urinary bladder, and sensations felt in the throat and lungs.
It’s unclear what these senses are though, other than the fact they are other senses.
