\nIf there was hyposecretion of the thyroid gland in a child; the child will suffer from cretinism. The symptoms of cretinism are dwarfism, mental retardation, etc.<\/p>\n

\n(d) Cortisone<\/p>\n
\n(a) Larynx
\nReason- Larynx is the sound box while the rest three i.e. glucagon; testosterone and prolactin are hormones.<\/p>\n
\nReason – Penicillin is an antibiotic while adrenaline; insulin; thyroxine are hormones.<\/p>\n
\nReason – Adrenaline is a hormone while the stomach, ileum and liver are the organs of the digestive system.<\/p>\n
\nReason- Insulin is secreted by the pancreas while TSH, GH, ADH are the hormones secreted by the pituitary gland.<\/p>\n
\nReason- Iodine is required for the synthesis of thyroxine hormone. While cretinism, goitre, myxoedema are the deficiencies occur due to the deficiency of thyroxine.<\/p>\n\n\n

Over secretion of growth hormone<\/td>\n<\/tr>\n \n (e) Enlargement of breasts in adult males<\/td>\n \n \n \n \n
\n(a) True
\nReason- Adrenaline is described as emergency hormone because during any emergency situation more adrenaline is secreted which makes the heart beat faster, increases the breathing, releases more glucose into the blood stream to fulfill the energy requirement.<\/p>\n
\nReason- The two different kinds of diabetes are diabetes insipidus caused due to insufficient secretion of vasopressin and the other is ‘diabetes mellitus’ caused due to hyposecretion of insulin but they cannot be described as mild and severe.<\/p>\n
\nReason-Iodine is an active ingredient in the production of the thyroxine hormone.<\/p>\n
\nReason- Pituitary gland controls the functioning of all the other endocrine glands.<\/p>\n
\nReason- Hormones are poured directly into blood the blood stream and control physiological processes by chemical means. Their action depends on the feedback mechanism.<\/p>\n
\nReason- Gigantism and dwarfism are controlled by the growth hormone from the pituitary gland. Growth hormone is much more active in children for their normal body growth along with which necessary substance required for the synthesis of growth hormone need to be consumed.<\/p>\n
\nEndocrine glands are ductless glands, means they pour their secretion i.e. hormones directly into the blood stream while the other glands are exocrine glands which have ducts. Through ducts they pour their secretions (not hormones) into the blood stream.<\/p>\n
\nHormones unlike enzymes are secreted by the endocrine glands only. Also the hormones unlike the enzymes are poured directly into the blood. Hormones can be peptides, steroids, amine but all enzymes are proteins.<\/p>\n
\nChemically hormones are peptides, amines or steroids. They are involved in regulating the metabolism of the body. They can bring about specific chemical changes during metabolic process. Therefore hormones can be termed as ‘chemical messengers’.<\/p>\n
\nIodine is an active ingredient in the production of the thyroxine hormone secreted by the thyroid gland. Thyroxine hormone is a very essential hormone for our body. In case of its abnormal secretions a person may suffer certain sever disorders. Therefore, it is an important nutrient for our body.<\/p>\n
\nAdrenaline is the hormone which prepares the body to meet any emergency situation. Adrenaline makes the heart beat faster. At the same time, it stimulates the constriction of the arterioles of the digestive system reducing the blood supply of the digestive system which makes the mouth dry.<\/p>\n
\nIf one adrenal gland is removed, the other one gets enlarged. This is to meet the requirement of hormones produced by the body.<\/p>\n\n
\nCause – under secretion of Insulin hormone
\nSymptoms – excretion of great deal of urine with sugar, Person feels thirsty and loss of weight. In severe cases, the person may lose the eye sight.<\/li>\n
\nCause – Under secretion of Anti-diuretic hormone
\nSymptoms – frequent urination resulting in loss of water from body and the person feels thirsty.<\/li>\n<\/ol>\n
\nThe Himalayan soil is deficient in iodine. Thus, the food grown in such soil also becomes iodine deficient. Due to this reason, when Himalayan people consume iodine deficient food, they do not get the proper intake of iodine. Therefore, people living in the low Himalayan hilly regions often suffer from goitre.<\/p>\n
