The peripheral vestibular organs are sensors for linear acceleration (gravity and head tilt) and rotation. Further, they regulate various body functions, including body stability, ocular movement, autonomic nerve activity, arterial pressure, body temperature, and muscle and bone metabolism. The gravitational environment influences these functions given the highly plastic responsiveness of the vestibular system. This review demonstrates that hypergravity or microgravity induces changes in vestibular-related physiological functions, including arterial pressure, muscle and bone metabolism, feeding behavior, and body temperature. Hopefully, this review contributes to understanding how human beings can adapt to a new gravitational environment, including the moon and Mars, in future.

了解前庭相关的生理功能可以为适应新的引力环境提供线索

周围的前庭器官是用于线性加速度(重力和头部倾斜)和旋转的传感器。此外,它们调节各种身体机能,包括身体稳定性,眼动,自主神经活动,动脉压,体温以及肌肉和骨骼代谢。考虑到前庭系统的高度塑性响应,重力环境会影响这些功能。这项审查表明,超重力或微重力引起前庭相关的生理功能的变化,包括动脉压,肌肉和骨骼的新陈代谢,进食行为和体温。希望这次审查有助于理解人类将来如何适应新的引力环境,包括月球和火星。
