Document Summary
Made up of dendrite (appear as ngers) that detect the stimuli/signal, axon (appears as the stem of the cell) it develops and sends the signal and the cell body which is the nucleus. It is a feel-good neurotransmitter in the brain. If levels are low it can lead to depression. Amphetamines : interferes with the re-uptake and lling of vesicles. Arteries, arterioles, veins, venules and capillaries: explain the difference between vasoconstriction and dilation. Provide an example when for each of those terms (i. e. when would they occur and in which part of the body). Vasodilation : dilation/relaxation of smooth muscle in walls of arterioles. ie; during exercising, in heart. No is a secreted chemical messenger produced in the endothelium and diffuses into smooth muscle cells. Used to make dynamite or used as a strong vasodilator in medicine. Beet root juice contains high amounts of organic no. Athletes use it to increase vasodilation in their bodies.
