Resumo: The pineal gland in vertebrates produces a hormone, a melatonin, which is related to circadian control and other physiological behavioral functions, such as the reproductive cycle, thermoregulation and thermal tolerance. The present study aimed to describe the morphological, morphometric and histological aspects of the pineal of Alouatta belzebul. Seven brains of adult specimens of this species were studied, of which the location of the gland in relation to the surrounding brain structures was calculated and its length and width were measured. Then, histological slides were prepared and stained with hematoxylin-eosin and PAS. It was observed that the pineal of A. belzebul is located superiorly and cranially to the cerebellum and superiorly to the superior colliculi and below the splenium of the corpus callosum. In addition, it can be functional as subcalous. It had an average length of 2.6 mm and an average width of 1.14 mm. Histologically, the gland is composed of irregular cords of pinealocytes and gliocytes. Pinealocytes pair melanin-like pigments. It was concluded that a pineal gland in Alouatta belzebul has similar aspects with some primates and carnivores, mainly in the su

O presente estudo teve como objetivo descrever os aspectos morfológicos, morfométricos e histológicos da pineal de Alouatta belzebul. Foram estudados sete encéfalos de espécimes adultos, dos quais se descreveu a localização da glândula em relação às estruturas encefálicas circunvizinhas e foram realizadas medidas de comprimento e largura da mesma. Em seguida foram preparadas lâminas histológicas e coradas pelas técnicas de hematoxilina-eosina e PAS. Observou-se que a pineal de A. belzebul localiza-se superior e cranialmente ao cerebelo e superiormente aos colículos superiores, abaixo do esplênio do corpo caloso. Além disso, pode ser classificada como subcalosa. Apresentou comprimento médio de 2,6 mm e largura média de 1,14 mm. Histologicamente a glândula apresentou-se composta por cordões irregulares de pinealócitos e gliócitos. Os pinealócitos apresentaram pigmentos semelhante à melanina. Concluiu-se que a glândula pineal em Alouatta belzebul tem aspectos semelhantes com alguns primatas e carnívoros, principalmente na classificação subcalosa.Submitted by Luciana Ferreira (lucgeral@gmail.com) on 2021-07-01T11:41:24Z No. of bitstreams: 2 Dissertação - Lucas José Santos Mascarenhas - 2021.pdf: 2213098 bytes, checksum: 773cef90714bcc410f1fef18d6d8e625 (MD5) license_rdf: 805 bytes, checksum: 4460e5956bc1d1639be9ae6146a50347 (MD5)Approved for entry into archive by Luciana Ferreira (lucgeral@gmail.com) on 2021-07-02T12:49:02Z (GMT) No. of bitstreams: 2 Dissertação - Lucas José Santos Mascarenhas - 2021.pdf: 2213098 bytes, checksum: 773cef90714bcc410f1fef18d6d8e625 (MD5) license_rdf: 805 bytes, checksum: 4460e5956bc1d1639be9ae6146a50347 (MD5)Made available in DSpace on 2021-07-02T12:49:02Z (GMT).
