Roatan doesnât have a dry season and the tropical weather of the Caribbean allows for the occasional thunderstorm. Off shore tradewinds, rain, and overcast are all part of the tropical landscape. However, no need to worry, just as fast as the clouds roll in, thats how fast the sunshine can reappear.
The Pituitary Gland. The pituitary is the âmasterâ endocrine gland (about the size of a pea) which is controlled by the hypothalamus to release a variety of hormones which modify the state of physiology and our basic motivations.he anterior pituitary secretes 9 different important hormones: 1  Growth hormone (also referred to as 'Human Growth Hormone', 'HGH' or 'GH' or somatotropin). 2  Thyroid-stimulating hormone (TSH). 3  Adrenocorticotropic hormone (ACTH). 4  Vasopressin. 5  Oxytocin. 6  Luteinizing hormone (LH).
A hormone is a chemical messenger produced by a cell that effects specific change in the cellular activity of other cells (target cells). Unlike exocrine glands (which produce substances such as saliva, milk, stomach acid and digestive enzymes), endocrine glands do not secrete substances into ducts (tubes).he two glands that are the most responsible for homeostasis is the thyroid and the parathyroid. The regulation of blood glucose concentration (through negative feedback) illustrates how the endocrine system maintains homeostasis by the action of antagonistic hormones.
