In physiology, a stimulus (plural stimuli) is a detectable change in the internal or external environment. The ability of an organism or organ to respond to external stimuli is called sensitivity.When a stimulus is applied to a sensory receptor, it normally elicits or influences a reflex via stimulus transduction.ne internal stimulus that causes hormone release is blood pressure. Hypotension, or low blood pressure, is a large driving force for the release of vasopressin, a hormone which causes the retention of water in the kidneys.
Thermoregulation is the process that allows the human body to maintain its core internal temperature. The state of having an even internal temperature is called homeostasis.All thermoregulation mechanisms are designed to return the body to homeostasis. section of your brain called the hypothalamus controls thermoregulation. It issues instructions to your muscles, organs, glands, and nervous system when it senses your core internal temperature is becoming too low or too high. Many factors can affect your bodyâs temperature.
