The passage of a tropical cyclone over the ocean causes the upper layers of the ocean to cool substantially, which can influence subsequent cyclone development. This cooling is primarily caused by wind-driven mixing of cold water from deeper in the ocean with the warm surface waters. hurricane or typhoon (sometimes simply referred to as a tropical cyclone, as opposed to a depression or storm) is a system with sustained winds of at least 34 metres per second (66 kn) or 74 miles per hour (119 km/h).
The adrenal glands (also known as suprarenal glands) are endocrine glands that produce a variety of hormones including adrenaline and the steroids aldosterone and cortisol. They are found above the kidneys and consist of a series of layers with different structure and functions. Each gland has an outer cortex which produces steroid hormones and an inner medulla. The adrenal cortex itself is divided into three zones: zona glomerulosa, the zona fasciculata and the zona reticularis. The adrenal cortex produces a class of steroid hormones called corticosteroids, named according to their effects. Mineralocorticoids, produced in the zona glomerulosa, help in the regulation of blood pressure and electrolyte balance.
Three arteries usually supply each adrenal gland: 1  The superior suprarenal artery, a branch of the inferior phrenic artery. 2  The middle suprarenal artery, a direct branch of the abdominal aorta. 3  The inferior suprarenal artery, a branch of the renal artery.
