The controversial restoration by Sir Arthur Evans of the ruins of the palace of Knossos. Greek archeologist Nikolaos Platon devised a chronology of the civilization based on excavations of Minoan palaces. He divides the civilization into the following eras:
Video: Adrenal Glands: Epinephrine, Norepinephrine & Stress Adaptation The adrenal medulla is the central portion of the adrenal gland. In this lesson, you will learn about the two hormones secreted by the adrenal medulla - epinephrine and norepinephrine - and how they help you deal with short-term stressors. Biology 105: Anatomy & Physiology / Science Courses
Norepinephrine. In addition to epinephrine, we see norepinephrine, which is a second hormone secreted by the adrenal medulla that increases heart rate, blood pressure, cardiac output and blood glucose levels.So we see that norepinephrine is very similar to epinephrine.t the center of the adrenal glands we see the adrenal medulla. This portion of the gland is stimulated by the sympathetic nervous system to secrete catecholamines, which are hormones that help you deal with short-term stress. There are two catecholamines. One is called epinephrine or adrenaline.
