腹部迷走神经是一种混合性神经。腹部迷走神经对血压的作用表明:电刺激动物完整膈下腹部迷走神经,在猫引起升压反应,在兔则多为血压先升后降的双相反应。如刺激其中枢端,猫兔均为升压反应,如刺激其外周端,猫为升压反应,而兔则为降压反应。 Abdominal vagus nerve is a mixed nerve. The effect of abdominal vagal nerve on blood pressure showed that: electrical stimulation of the intact subdiaphragmatic vagus vagus nerve in animals resulted in a step-up response in cats, and biphasic responses of blood pressure increased first and then decreased in rabbits. Such as stimulating its central end, cats and rabbits are booster reaction, such as stimulating the outer end, the cat is a step-up response, while rabbits are antihypertensive response.
