Somatosensory cues rely on what condition to provide orientation cues?

Explanation:
Gravity provides a constant reference vector that the somatosensory system uses to gauge body position in space. Proprioceptive and cutaneous signals tell you where your limbs are and what they're doing, but without a stable downward pull to reference, tilt and orientation become ambiguous. The brain combines these somatosensory cues with the gravity vector (via the otoliths in the vestibular system) to determine up and down, especially when vision or other cues are limited. Humidity, temperature, and noise don’t give directional information about body orientation, so they don’t serve this function.
