As far as is known an epiphysis is present in all ver tebrates with the exception of mixinoids and crocodilia. In man the pineal body is pear shaped, lies just beneath the sp...

The Immune-Pineal Axis: the Role of Pineal and Extra-Pineal Melatonin in Modulating Inflammation

Participation of the pineal gland and melatonin in the innate immune response is part of a dynamic and intricate network that acts throughout the inflammatory response, integrating signaling pathways and regulatory processes at the molecular, cellular and organism levels. The pineal gland is a target for pathogen-associated molecular patterns and for inflammatory mediators, and melatonin, which...

Effect of Feeding the Pineal Body upon the Development of the Albino Rat

Of these, fourteen rats were fed the pineal powder and ten were used as control subjects. Observations in regard to developmental changes and microscopic examination of the endocrine glands and reproductive organs were made. The ...
