The arrangement and numbers of intralaryngeal ganglia and associated neurons in humans and four mammals (dogs, rabbits, guinea pigs and rats) were investigated morphologically and compared with the results obtained in the cat which have been reported previously. Intralaryngeal ganglia were mostly distributed in branches of the internal branch of superior laryngeal nerve in all species, dorsal and/or dorsolateral to the posterior cricoarytenoid muscle in humans, dogs and cats and around the inferior laryngeal nerve in humans, dogs, cats, guinea pigs and rats. The total number of laryngeal ganglionic neurons was 2,000 to 2,400 in humans, 300-450 in dogs, 600-800 in cats, 250-320 in rats, and 100-150 in rabbits and guinea pigs. More than 80 percent of ganglionic neurons were present in the supraglottis in all species, except the rat, in which about 60 percent were in the subglottis. Each ganglion in all species existed within the nerve bundle, and was chiefly encapsulated with fibrous tissue, many ganglionic cells, glial cells, Schwann cells, vessels and connective tissue. The present morphological study of intralaryngeal ganglia in humans and four mammals suggests that the laryngeal ganglionic neurons have the same arrangement as in cats.
对人类和四种哺乳动物（狗、兔、豚鼠和大鼠）喉内神经节及相关神经元的排列和数量进行了形态学研究，并与先前报道的猫的研究结果进行了比较。在所有物种中，喉内神经节大多分布在喉上神经内支的分支中，在人类、狗和猫中位于环杓后肌的背侧和/或背外侧，在人类、狗、猫、豚鼠和大鼠中围绕喉下神经。人类喉神经节神经元的总数为2000至2400个，狗为300 - 450个，猫为600 - 800个，大鼠为250 - 320个，兔和豚鼠为100 - 150个。除大鼠外，所有物种中超过80%的神经节神经元存在于声门上区，大鼠约60%的神经节神经元位于声门下区。所有物种的每个神经节都存在于神经束内，主要由纤维组织、许多神经节细胞、神经胶质细胞、施万细胞、血管和结缔组织包裹。目前对人类和四种哺乳动物喉内神经节的形态学研究表明，喉神经节神经元的排列与猫相同。
