从形态学上看，蛙的输卵管由衬里上皮和管状胶状分泌腺组成。输卵管可分为六个区域（指定为R1前-R6后）的基础上的差异染色的果冻腺。这些区域的尺寸分别为1、5、6、3、20和3 cm。这些区域对应于6个组织化学上不同的胶状物层（指定为最靠近卵的J1至最远离卵的J6），其在卵在输卵管中逗留期间沉积在卵周围。每个输卵管区域的长度和个别果冻层的厚度之间的相关性进行了观察。也就是说，J5最厚，其次是J3、2、6、4和最薄的J1。
Morphologically the oviduct of the frog, Rana pipiens, consists of a lining epithelium and tubular jelly‐secreting glands. The oviduct can be divided into six regions (designated R1 anteriorly—R6 posteriorly) based on the differential staining of the jelly glands. The regions measured 1, 5, 6, 3, 20 and 3 cm, respectively. These regions correspond to 6 histochemically distinct layers of jelly (designated J1 nearest the egg through J6 farthest from the egg) which are deposited around the egg during the egg's sojourn in the oviduct. A correlation between lengths of each oviducal region and thickness of individual jelly layers was observed. That is, J5 is the thickest, followed by J3, 2, 6, 4 and J1 which is thinnest.
