What is the cause of hypersecretion of growth hormone?
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.
Which of the following is a condition caused by the hypersecretion of growth hormone by the anterior pituitary and results in an increase in overall body size?
Acromegaly and gigantism are disorders of the abnormal excess secretion of growth hormone. Gigantism occurs when growth hormone hypersecretion occurs before the fusion of the long bone epiphysis and is characterized by tall stature.
What are the effects of hypersecretion?
breathing rate are increased , while digestive processes are decreased. [No known effects are due to hyposecretion of these, but hypersecretion can caused hypertension, increased blood glucose level , and high heart rate]. The only gland that is both exocrine and endocrine in physiology.
What are the causes of hypersecretion or Hyposecretion?
Overview
- Diseases of the endocrine system involve the secretion of too much or not enough hormone.
- When too much hormone is secreted, it is called hypersecretion.
- Hypersecretion by an endocrine gland is often caused by a tumor.
- For example, a tumor of the pituitary gland can causehypersecretion of growth hormone.
Why hypersecretion of growth hormone in adults does not cause further increase in height?
In adults, hypersecretion of GH does not cause further increase in height because epiphyseal plates close after adolescence. Epiphyseal plate is a hyaline cartilage plate at each end of a long bone where new bone growth takes place.
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 hypersecretion of ACTH?
A disease of the PITUITARY GLAND characterized by the excess amount of ADRENOCORTICOTROPIC HORMONE secreted. This leads to hypersecretion of cortisol (HYDROCORTISONE) by the ADRENAL GLANDS resulting in CUSHING SYNDROME.
Which disease is caused by hypersecretion of glucocorticoids?
Cushing’s syndrome arises from the repeated hypersecretion of glucocorticoids. It can be caused by either an adrenal tumor or by hypersecretion of adrenocorticotropic hormone (ACTH) from the anterior pituitary gland. It is predominantly due to an excess of the glucocorticoid cortisol.
What is meant by primary hypersecretion?
Hypersecretion – Primary hypersecretion is a gland itself secreting too much hormone while secondary hypersecretion is the excessive stimulation of a gland by its tropic hormone.
What are the effects of hypersecretion of growth hormone?
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.
What does Hyposecretion mean?
Hyposecretion is when the amount of hormones that are released is too low. There are many types of disorders that can result when too much or too little of a hormone is released.
Which of the following disorders are caused by hypersecretion of their concerned hormones?
| Disorder | Caused by |
|---|---|
| Acromegaly | Hypersecretion of growth hormone (GH) in adults |
| Diabetes Mellitus | Hyposecretion of insulin |
| Eunuchoidism | Severe hyposecretion of sex hormones (Androgens in male and estrogens in females) |
| Exophthalmic goitre | Hypersecretion of thyroid hormones |
