Endocrine glands are ductless glands and their secretions are known as Hormones. They are chemical messengers which are secreted in trace amounts and affects the target organ of the body.
Pituitary gland release several hormones which regulate the functioning of different parts of the body. Growth hormone, PRL, TSH, ACTH, LH, FSH, MSH, oxytocin and vasopressin are the hormones released by the pituitary gland.
Thyroid glands are located in our neck region and secretes thyroxine, TCT and calcitonin hormone. On the other hand Parathyroid gland is located on the posterior side of thyroid gland and release PTH.
Adrenal glands are supra-renal glands which consists of two parts; cortex and medulla which releases certain hormones to regulate the process of human body.
Gonads,testes in male and ovary in female are the reproductive glands which secretes hormones that helps in the reproduction of male and female. Testes secrete androgen, inhibin,AMF and ovary release estrogen and progesterone.
Pancreas is a composite gland which function as both exocrine and endocrine gland. The endocrine pancreas consists of islets of langerhans. Alpha cells of pancreas secretes glucagon and beta cells release insulin.
Thymus gland is a lymphoid organ that secretes the peptide hormone thymosin. Thymus gland promotes the development of specific cell of the immune system called as T- lymphocytes.
Pineal gland is an endocrine gland found in the cerrebral ventricle in the brain midline. Pineal gland release melatonin hormone which controls circadian rhythm of the body.
Hypothalamus is the basal part of the brain which contain neuro-secretory cells called nuclei These nuclei produce hormones which regulate the functioning of pituitary hormones.
Hormones are natural organic substances that regulate growth, metabolism of the body. Protein hormones perform their action through extracellular receptors while mode of action of steroid hormones is through intracellular receptor.
Dwarfism is a condition in which the growth of the individual is very slow resulting in short stature. There are two types of dwarfism; Proportionate and Disproportionate dwarfism.
Acromegaly is a hormonal disorder that results from the excess of Growth hormone (GH)in the body. In Acromegaly pituitary produces excessive amounts of growth hormone.It is often diagnosed in middle aged adults and can result in serious illness and premature death.
Cretinism refers to severe hypothyroidism which is due to the deficiency of thyroid hormone. This is a medical condition present at birth and characterized by physical deformity, dwarfism and mental retardation..
Goitre is an enlarged thyroid gland that causes the neck to swell. The thyroid gland is controlled by the pituitary gland which prompts the thyroid to secrete hormones T4 and T3 by releasing TSH. Excessive stimulation of the thyroid gland by TSH can result in goitre.
It is preferably known as Diabetes Mellitus. It is a group of metabolic disorders in which the person has high blood glucose due to inadequate insulin production. There are three types of diabetes; type-1, type-2, Gestational diabetes.
Exopthamic goitre is also known as Grave's disease. It is the most common form of hyperthyroidism and thyrotoxicosis. It results in an abnormal over activity of the thyroid gland which produce too much of thyroid hormone; thyroxine.
Addison's disease also called as primary adrenal insufficiency, the adrenal glands do not produce enough hormone named cortisol and aldosterone. Cortisol helps in maintaining body response towards stress.
Hormones are chemical substances produced in one part of the body and carried by blood to target organ where it regulates the processes. Hormones regulate metabolic activities in various tissues.
