Test 01 - Introduction Receptor cells use chemical transmitters to communicate with relay cells or afferent nerve fibers. In all sensory systems‚ accessory structures modify‚ in some way‚ the stimulus going to the receptor surface. Receptors are electrically polarized cells and therefore have a resting membrane potential. Stimuli produce‚ in the appropriate receptors‚ a change in the electrical properties that is known as the receptor or generator potential. The two ways in which sensory stimuli

chemists an avenue for studying the chemical structure of the compound and more efficient methods of synthesis that are cheaper and shorter. The physiological function of aspirin can be attributed in its ability to interfere with the production of prostaglandins‚ a naturally secreted chemical by the body which causes pain‚ headaches and blood clotting. The latter is actually a downside of the drug‚ because of possible extreme blood loss of patients who are frequently using the drug. But also‚ this property

Angiotensin 1 is converted to angiotensin 2 in the lungs. Angiotensin 2 causes vasoconstriction and stimulates aldosterone released from the adrenal cortex. Aldosterone causes retention of water‚ which increases blood volume. The kidneys also produce prostaglandin E2 and prostacyclin‚ which help maintain renal blood flow through vasodilation. These mechanisms increase arterial blood pressure and renal blood flow. 2) Ureters – The ureters are a tubular structure that enters the urinary bladder. They transport
