Research on the pineal gland in pigs has gained significant interest due to the physiological similarities between pigs and humans, making pigs a relevant animal model for studying pineal function and its potential applications in medicine. All though recent studies have focused on the pineal gland (mostly regarding structure and innervation of the gland), our own research highlighted in the present paper, as a result of optical and electronic microscopy (TEM and SEM), details of histological and ultramicroscopic organization of the constituent cell types of the pineal gland in pigs. We focused on demonstrating the possible physiological mechanisms of secretion, as well as the elimination pathways of the active endocrine biological products (indole and peptide hormones) of the component cells of the pineal gland. Our research significantly contributes with important information about the function and the internal cell mechanisms of this important endocrine gland and provides valuable insights for biomedical applications that can translate in human medicine.
