Plant hormones are specialized chemical substances produced by plants. They are the main internal factors controlling growth and development. Hormones are produced in one part of a plant and transported to others‚ where they are effective in very small amounts. Depending on the target tissue‚ a given hormone may have different effects. Plant hormones play an integral role in controlling the growth and development of plants. A plant hormone is generally described as an organic compound synthesized

Hormones and the Endocrine System 26.1 Chemical and electrical signals coordinate body functions The Endocrine System is a group of interacting glands and tissues throughout the animal body that produce and secrete chemical to initiate and maintain body functions and activities. Chemical Signals -Hormones - are released into the bloodstream by endocrine cells and carried to all locations in the body Consists of all hormone secreting cells Works with the nervous system in regulating body activities

Gonadal sex hormones are produced by gonadotropins (FSH- Follicle Stimulating Hormone and LH- Luteinizing hormone) from the anterior pituitary gland located at the base of the brain. They stimulate male and female gonads to produce hormones of their own. FSH and LH secretion is controlled by GnRH (gonadotropin-releasing hormone)‚ which is a releasing hormone from the hypothalamus. The sex of an embryo is determined at fertilization‚ but secondary sex characteristics develop at puberty. Testosterone

referred to as hormones which act as “chemical messengers” in an effort to regulate particular bodily functions such as metabolism and growth. These hormones are produced by the pancreas‚ thyroid‚ pituitary‚ pineal‚ and adrenal glands which are also referred to as the endocrine system. Hormones are additionally produced in the ovaries in women and the testes in men. The secretions of particular hormones assist the body in maintaining a state of balance or homeostasis. When one or more hormones within the

Aldosterone and Hormone Replacement Therapy Aldosterone falls in the class of hormone called mineralocorticoids‚ produces by the adrenal glands and is found near the kidneys. It sustains blood pressure‚ water and salt balance within the body. This procedure is assisting the kidneys to preserve sodium and excrete potassium in order to maintain a balance. If Aldosterone production falls‚ there isn’t enough regulation of salt and water balance (as aldosterone is being lost through urination) triggering

C) increased secretion of thyrotropin-releasing hormone from the hypothalamus. D) inhibition of parathyroid hormone release from the parathyroid glands. 2. Growth hormone is secreted into the bloodstream by the A) anterior pituitary. B) posterior pituitary. C) hypothalamus. D) thymus. 3. A patient has syndrome

How Hormones Effect the Endocrine System Introduction: The endocrine system primarily relies on the negative feedback mechanism. The endocrine system influences metabolic activities by sending out chemical messengers through the blood called hormones. Once released into the blood these hormones are transported throughout the body. The effects of these hormones are wide spread and vary from reproduction‚ growth and development‚ immunities‚ maintaining electrolyte levels‚ water and nutrient balance
