Anatomical study of the pineal gland in capybara (Hydrochoerus hydrochoeris)
Keywords:Pineal body, Capybaras, Hidrochaerus.
AbstractThe pineal gland was studied macro-and microscopically in 19 adult and young capybaras (Hydrochoerus hydrochoeris) 13 females and 6 males. Pineal gland was present in all specimens between the cerebrum and the cerebellum and was formed by a base with two peduncles, a stem and an apex. The gland was in the roof of the III ventricle, next to the rostral coliculi, either
whish or brownish.The apex contained a cavity. Pineal gland was 2.2 cm long, and dimensions of the base, stem and apex were 1.3 mm, 1.2 mm and 2.0 mm respectively. The connective tissue capsule at least in part, contained blood vessels. Pineal parenchyma exhibited pinealocytes, with nuclear and interstitial cells.
