Hormonieritys
Hormonieritys is the process by which cells release hormones into the extracellular space, enabling chemical signals to coordinate physiological functions. Hormones may act at distant sites via the bloodstream (endocrine secretion), be released into local tissue spaces to affect neighboring cells (paracrine), or act on the secreting cell itself (autocrine). Neurosecretory cells provide a bridge between the nervous system and the endocrine system.
Secretory mechanisms vary: many peptide and protein hormones are stored in secretory granules and released by
Transport and action: once in the bloodstream, hormones may bind carrier proteins or circulate freely. Target
Regulation and clinical relevance: Hormonieritys is tightly controlled by feedback systems, notably the hypothalamic-pituitary axis. Dysregulation
