What is the mass of lymphoid tissue located above the heart? When the stressful situation ends, the nerve impulses to the adrenal glands are lowered, meaning that the adrenal glands stop producing adrenaline. In physiology, a stimulus is a detectable change in the physical or chemical structure of an organism's internal or external environment.The ability of an organism or organ to detect external stimuli, so that an appropriate reaction can be made, is called sensitivity (excitability). any substance that the body regards as being foreign, and includes viruses, bacteria, toxins, and transplanted tissues.
