摘要

本研究旨在阐明小猫头鹰(Athene noctua)眼眶腺的解剖、组织学和组织化学结构,揭示其在视觉中的作用。小猫头鹰的泪腺比哈德氏腺小。小猫头鹰的哈德氏腺扁平,呈泪珠状,呈粉红色,位于腹斜肌和锥体肌之间。而泪腺呈圆柱形,在背腹方向受压,位于眶背缘狭窄的细长窝内。两腺体均为复合管状肺泡型。哈德氏腺腺泡由立方状腺细胞排列,而泪腺腺泡由柱状细胞排列。小猫头鹰的哈德氏腺属于i型。小猫头鹰的哈德氏腺和泪腺含有中性和酸性黏液物质。介绍

ANATOMICAL, HISTOLOGICAL AND HISTOCHEMICAL STUDIES OF ORBITAL GLANDS OF LITTLE OWL ATHENE NOCTUA
The present study aimed to illustrate the anatomical, histological and histochemical structure of the two orbital glands of the little owl, Athene noctua with revealing their role in the vision. In little owl, the size of lacrimal gland appears smaller than that of the Harderian gland. The Harderian gland of the little owl is flat and looks like teardrop in shape with pink color and located between the ventralis oblique muscle and pyramidalis muscle. While, the lacrimal gland is cylindrical, compressed in the dorsal-ventral direction and is located on the dorsal edge of the orbit within a narrow elongated fossa. Both glands are compound tubuloalveolar type. The acini of Harderian gland are lined by cuboidal glandular cells whereas the lacrimal gland acini are lined by columnar cells. The Harderian gland in the little owl is classified as a type I. The Harderian gland and lacrimal glands of the little owl contain neutral and acid mucosubstances. INTRODUCTION
