GH hypersecretion results in gigantism or acromegaly, a condition associated with significant morbidity and mortality, while GH deficiency results in growth retardation in children and the GH deficiency syndrome in adults.
Which of the following hormones is secreted by the ovary and adrenal cortex?
Ostrogen is secreted by the adrenal cortex as well as the ovaries, and is present in the blood of all females from puberty through to the menopause. oestrogen acts on the structure of the reproductive organs, especially during the menstrual cycle.
What is a characteristic of acromegaly quizlet?
Symptoms of acromegaly include an enlarged face and hands. Changes to the face may cause the brow bone and lower jaw to protrude, and the nose and lips to get larger. Acromegaly is a hormonal disorder that develops when your pituitary gland produces too much growth hormone during adulthood.
Which of the following is a description of gonadotropins *?
Gonadotropins are glycoprotein hormones secreted by gonadotropic cells of the anterior pituitary of vertebrates. These hormones are central to the complex endocrine system that regulates normal growth, sexual development, and reproductive function.
Which of the following is caused by hypersecretion of growth hormones in soft tissue thickening and spade like hands?
Abstract. Hypersecretion of growth hormone (GH) before epiphyseal closure leads to gigantism.
What is the cause of hypersecretion of growth hormone?
Gigantism and acromegaly are usually caused by a pituitary adenoma that secretes excessive amounts of growth hormone (GH); rarely, they are caused by non-pituitary tumors that secrete growth hormone–releasing hormone (GHRH). Gigantism occurs if GH hypersecretion begins in childhood, before closure of the epiphyses.
What is the target gland of thyrotropin hormone?
Thyroid-stimulating hormone, also known as thyrotropin, is secreted from cells in the anterior pituitary called thyrotrophs, finds its receptors on epithelial cells in the thyroid gland, and stimulates that gland to synthesize and release thyroid hormones.
Which of the following is a feature of tetany?
Tetany is a symptom characterized by the involuntary contraction of muscles that usually results from low calcium levels in the blood (i.e., hypocalcemia). Common symptoms of tetany include numbness around the mouth, muscle cramps, and paresthesias affecting the hands and feet.
What causes hypersecretion of thyroid hormone?
Hypersecretion of thyroid stimulating hormone (TSH), which in turn is almost always caused by a pituitary adenoma, accounts for much less than 1 percent of hyperthyroidism cases.
Which of the following is a description of tetany?
Tetany is a symptom characterized by muscle cramps, spasms or tremors. These repetitive actions of the muscles happen when your muscle contracts uncontrollably.
Is FSH a gonadotropin?
Gonadotropins are two hormones, luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which are normally produced by the pituitary gland. These hormones stimulate the ovaries to produce a follicle, which contains an egg (oocyte) and to release the egg from the ovary.
What causes hypersecretion of growth hormone?
