前庭系统的电刺激或自然刺激会导致血压和呼吸运动输出的变化。在猫鼻子向上的前庭刺激过程中，交感神经系统的兴奋性会增加；这种反应适合抵消直立性低血压，这种低血压可能是在垂直攀登等运动过程中因鼻子向上的身体旋转而导致的。此外，麻醉或清醒的猫的前庭神经的横断会影响纠正因鼻子向上倾斜而导致的血压下降的能力。前庭系统也对呼吸肌有影响；这些效应适合参与呼吸肌活动的调整，这是抵消身体位置变化期间对这些肌肉产生的机械约束所必需的。因此，这些数据表明前庭系统对自主神经和呼吸系统的影响有助于维持运动过程中的体内平衡。
Electrical or natural stimulation of the vestibular system results in changes in blood pressure and respiratory motor output. An increase in excitatory drive on the sympathetic nervous system occurs during nose-up vestibular stimulation in cats; this response is appropriate to offset orthostatic hypotension that could result from nose-up body rotations during movements such as vertical climbing. In addition, transection of the vestibular nerves in anesthetized or awake cats compromises the ability to correct decreases in blood pressure that result from nose-up body tilt. The vestibular system also has influences on respiratory muscles; these effects are appropriate to participate in making adjustments in the activity of respiratory muscles that are necessary to offset mechanical constraints on these muscles that occur during changes in body position. These data thus suggest that the influences of the vestibular system on the autonomic and respiratory systems serve to maintain homeostasis during movement.
