Resumo: Following the discovery of the melatonin by Lerner et al. (1958), new research and perspectives were developed in order to improve the knowledge regarding the pineal gland. This hormone is not only related to the circadian control but also influences other behavioral functions such as the reproductive cycle and thermoregulation. In this study the morphology of the pineal gland (epiphysis cerebri) from 20 dogs were analyzed by means of macroscopic and microscopic evaluation. The shape of the gland ranged from conic to “tongue-like shape” (in relation to human tongue). The gland color ranged from beige to gray-brownish and it had a gelatinous consistency. The width and length of the glands ranged from 1.38 to 2.39 mm and 1.53 to 2.96 mm, respectively. Capsule, septa, pinealocytes, glial cells and pigment granules were microscopically found in all glands. No calcareous concretions were observed.

(1958), novas pesquisas e perspectivas surgiram tornando a pineal uma estrutura mais estudada. Além disso, sabe-se que este hormônio está relacionado com o controle circadiano e outras funções comportamentais fisiológicas como o ciclo reprodutivo e termorregulação. Neste trabalho, foram utilizados 20 cães e estudamos a morfologia das glândulas, empregando uma análise macroscópica e microscópica. O formato das pineais variou de cônico a glossóide (em relação à língua humana); cor entre bege e marrom-acinzentado e apresentaram consistência gelatinosa. A largura e o comprimento das glândulas variaram respectivamente de 1,38 a 2,39 mm e de 1,53 a 2,96 mm. Quanto à microscopia, utilizamos coloração de eosina-hematoxilina (HE), e em todas as pineais observamos a presença dos seguintes componentes: cápsula; septos ou trabéculas pinealócitos; células da glia; grânulos de pigmentos, e não foram notadas concreções calcáreas.UEL2008-08-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/286510.5433/1679-0359.2008v29n1p137Semina: Ciências Agrárias; Vol. 29 No. 1 (2008); 137-150Semina: Ciências Agrárias; v. 29 n. 1 (2008); 137-1501679-03591676-546Xreponame:Semina.
