#secretion

• Allocrine — A term describing a gland, tissue, or secretion mechanism in which the produced biochemical substances are released outside the organism or toward another individual of the same or a different species, acting as external chemical messengers (such as pheromones or allomones). In a structural sense, it defines inter-organism exocrine chemical communication processes, opposed to classical endocrine or paracrine systems.
• Anacidity — The pathological or total absence of hydrochloric acid from the gastric juice secretion, structurally settled at the level of the stomach mucosa. This clinical phenomenon, often correlated with severe gastric gland atrophy or pernicious anemia, severely disrupts the normal protein digestion process and promotes the growth of abnormal bacterial flora in the upper digestive tract.
• Androblastoma — A rare androgen-secreting tumor located in the ovary (also known as a Sertoli-Leydig cell tumor) or testis, developing from the embryonic structures of primitive sex cords. Structurally, this neoplastic proliferation frequently induces clinical phenomena of virilization and secondary masculinization in female patients, requiring precise histopathological diagnosis and surgical excision.
• Apepsia — A severe form of digestive dysfunction characterized by the total absence or complete cessation of pepsin and hydrochloric acid secretion in the gastric juice, leading to the stomach's inability to perform the chemical breakdown of proteins. This pathological phenomenon is frequently associated with advanced stages of atrophic gastritis and pernicious anemia.
• Apocrine — Pertaining to a type of exocrine glands whose secretory cells lose a portion of their apical cytoplasm during the elimination of the biological product; characteristic of secretion where the substance is released along with cellular fragments. In human anatomy, the term applies specifically to certain large sweat glands in the axillae or groin area, which become active at puberty.
• Apocrisis — A term used in ancient humoral medicine to denote the elimination, evacuation, or secretion of noxious matters, altered blood, or residues from the organism; the product of this pathological secretion. The concept was based on the idea that restoring a patient's health depended directly on purifying bodily fluids through natural biological crises.
