Abstract

The innervation of pelage, guard hairs and vibrissae hairs was studied in five species of marsupial mammals by means of electron microscopy for the first time. This study showed that members of different superfamilies in marsupial mammals displayed the same pattern of hair innervation. This also resembled the pattern seen in the placental mammals. All types of hairs had both longitudinal and transverse lanceolate nerve terminals. Pelage hairs did not have any Merkel cells. Guard hairs were very richly innervated and had free nerve endings, lanceolate nerve endings, many Merkel cells with their associated nerve endings and pilo-Ruffini nerve endings. Vibrissae hairs had free nerve endings, Merkel nerve endings and lamellated corpuscles, but pilo-Ruffini nerve endings were not seen in this investigation. Because of the profusion and variety of innervation in guard hairs of the marsupial mammals, these hairs may have a similar function to vibrissae hairs in placental mammals.

摘要

首次通过电子显微镜对五种有袋类哺乳动物的被毛、触须和刚毛的神经支配进行了研究。这项研究表明,有袋类哺乳动物不同超科的成员表现出相同的毛发神经支配模式。这也与胎盘类哺乳动物的模式相似。所有类型的毛发都有纵向和横向的披针形神经末梢。被毛没有任何默克尔细胞。触须神经支配非常丰富,有游离神经末梢、披针形神经末梢、许多带有相关神经末梢的默克尔细胞和毛鲁菲尼神经末梢。刚毛有游离神经末梢、默克尔神经末梢和环层小体,但在本研究中未观察到毛鲁菲尼神经末梢。由于有袋类哺乳动物触须神经支配的丰富性和多样性,这些毛发可能与胎盘类哺乳动物的触须具有相似的功能。
