Which type of hormone acts locally on the cells that release it?

Local hormones, also known as paracrines, are chemical messengers that are secreted by cells and act on nearby target cells in the same tissue. This allows for rapid and localized responses within a specific area of the body, unlike circulating hormones that travel through the bloodstream to reach more distant target cells. Local hormones can modulate various physiological processes in their immediate environment without affecting the entire organism. Therefore, the key characteristic of local hormones is their localized action, which distinguishes them from other hormone types that may have a broader systemic effect.
