Morphological Study of Intralaryngeal Ganglia and Their Neurons in the Cat

Arrangement and number of intralaryngeal ganglia and ganglionic neurons: comparative study of five species of mammals

“…The results of the present study are described together with those of our previous investigation in cats (Yoshida et al, 1992;Shimazaki, 1993;Yoshida et al, 1993).…”

“…Finally, in our previous investigations of the cat (Yoshida et al, 1992;Shimazaki, 1993;Yoshida et al, 1993) the arrangement of intralaryngeal ganglia and their neurons and functional aspects of ganglionic perikarya have indicated that the ganglionic neurons are mainly parasympathetic and also partly sympathetic and sensory. In other mammals, to determine whether similar characteristics are shared, further study is needed.…”

“…As regards the feline laryngeal ganglia, we have investigated not only arrangement, shape, size and number of ganglia and their neurons, but also the nature of ganglionic neurons (Shimazaki, 1993;Tanaka et al, 1993;Yoshida et al, 1993). Tsuda et al (1990) also reported that at least three or four local ganglia (about 0.5 mm in diameter) were located mainly along the Int-SLN and around the laryngeal ventricle, and the ganglionic neuron was about 30 u,m in diameter and had an elliptical shape.…”

“…In the previous literature, no remarkable reports concerning the intralaryngeal ganglia are to be found. The authors have investigated not only the arrangement of intralaryngeal ganglia and their neurons but also the functional features of ganglionic neurons in the cat by means of several methods (Yoshida et al, 1992;Shimazaki, 1993;Yoshida et al, 1993). However, in other animals, including dogs, information on distribution, number and size of ganglia and ganglionic neurons in the larynx is still lacking.…”
