Physiological evidence that the vestibular system participates in autonomic and respiratory control.

摘要: Electrical or natural stimulation of the vestibular system results in changes blood pressure and respiratory motor output. An increase excitatory drive on sympathetic nervous occurs during nose-up cats; this response is appropriate to offset orthostatic hypotension that could result from body rotations movements such as vertical climbing. In addition, transection nerves anesthetized awake cats compromises ability correct decreases tilt. The also has influences muscles; these effects are participate making adjustments activity muscles necessary mechanical constraints occur position. These data thus suggest autonomic systems serve maintain homeostasis movement.
