Anatomia do sistema reprodutor feminino de Alouatta belzebul (Linnaeus, 1766)

Abstract: RESUMO O conhecimento da anatomia de qualquer animal silvestre é de fundamental importância para sua preservação e proteção. Neste contexto, o presente estudo objetivou descrever a morfologia do sistema reprodutor feminino de Alouatta belzebul. Foram utilizados seis espécimes de A. belzebul, fêmeas, adultas, e livres de lesões. Observou-se macroscopicamente que os ovários têm características morfológicas em formato ovoides, com superfície lisa, e, na análise histológica na região de córtex, evidenciou-se folíc… Show more

“…Thus, blood flow is blocked; it causes ischemia in the region responsible for the necrosis of the Initially, Old World primates were considered menstrual cycle species, whereas New World primates had estrous cycle because macroscopic features of endometrial bleeding were not observed (Blaffer & Whitten, 1987). However, according to Pereira et al (2020), endometrial features associated with the menstrual cycle have been also reported in Atelidae. The brown howler monkey (Alouatta guariba) exhibits areas of desquamation on the surface of the uterine epithelium, erythrocytes in the lumen of the endometrial glands, and subepithelial blood leakage; however, no cilia or microvilli in the epithelial cells or macroscopic bleeding were observed (Pereira et al, 2020).…”

Kaiser (1947) evaluated the uterus of the mantled howler (Alouatta paliatta) and did not observe spiral or analogous arteries in the endometrium.…”

“…The morphological information about the base nuclei allows the understanding of motor behavior and ethological and behavioral aspects of different species, as well as supports the development of conservation strategies (7,9,10) . The species Alouatta belzebul was evaluated in other anatomical studies, such as the spinal cord (11) , vascularization of the brain (12) , digestive tract (13) , dura mater venous sinuses (14) and female reproductive system (15) , however, the islands of grey substance (cellular bodies) inside the white substance of the brain and of extreme importance for motor control called basal nuclei, were not studied in this species. The basal nuclei are composed of masses of gray substance (nuclei) located inside the medullary white center of the brain which is the white substance of the telencephalon.…”
