Abstract:
A study was conducted to reveal the structural organisation of tonsil in prenatal stages of goat. Lingual tonsil was close to the developing skeletal muscle fibers underneath the mucosa on day 73 of gestation. With advancing age the size of tonsil increased and by day 112 the proprio-submucosa constituted a diffuse lymphatic tissue (DLT). At day 73 proprio-submucosa of pharyngeal wall was dominated with densely packed small, medium and large lymphocytes whereas, in day old neonates besides lymphocytes macrophages, plasma cells, reticular cells, megakaryocytes were also evident. Aggregated lymphatic nodules could not be observed in palate of all the goat foeti studied, whereas sporadic lymphocytes were seen from 106 days of gestation and onwards.
