| two generations of the tongue and gustatory organs in the development of hynobius dunni tago. | in the development of hynobius dunni there are two consecutive generations of the tongue and two generations of gustatory organs (taste buds and taste disks). the anlage of the developing secondary tongue appears just in front of the free ending of the primary tongue beginning at the larval developmental stage 62. from stage 67, a gradual reduction in the anterior part of the gill skeleton that supports the primary tongue occurs as the developing secondary tongue replaces the primary one. the li ... | 2002 | 12171480 |
| evidence for a frontal-organ homologue in the pineal complex of the salamander, hynobius dunni. | the pineal complex of larval and adult salamanders, hynobius dunni, was examined by light and scanning electron microscopy. this pineal complex displays an anterior and a posterior portion, both of which possess a lumen. the anterior lumen is small and closed, whereas the posterior lumen is in open communication with the third ventricle. cell processes of the photoreceptor cells and microvilli of the supportive cells are visible in both lumina. the anterior part of the complex is formed by an in ... | 1993 | 8339321 |
| the blood vascular architecture of the salamander external gill: a scanning electron microscopic study of corrosion casts. | the blood vascular architecture in three-paired external gills of salamander tadpoles, hynobius dunni tago, was demonstrated with special reference to metamorphosis by scanning electron microscopy of vascular corrosion casts. in the fully developed gill, each of the three-paired afferent branchial arteries gave off secondary afferent filament arterioles. the afferent filament arteriole drained toward the efferent filament arteriole, forming the loop at the posterior extremity of the gill filamen ... | 1989 | 2812682 |
