This lecture covers the histogenesis of epithelial and glandular tissues, focusing on the development of exocrine and endocrine glands. Topics include the formation of acini, duct cells, and secretory portions, as well as the classification of exocrine glands based on their structure. The lecture also discusses the secretion of mucins, the differentiation between serous and mucous glands, and the development of sweat glands. Emphasis is placed on the morphological features of glandular cells, such as the Golgi apparatus, endoplasmic reticulum, and mitochondria.
