Hypothalamus 1. What is the molecular mechanism to release TRH? TRH refers to the thyrotropin-releasing hormone. This hormone is produced by the hypothalamus. Before the full activity of TRH, some tightly controlled processes occur in the body including the appropriate folding of prohormone to move to the secretary pathway, the processing after translation, and movement of the peptides, which are processed, towards the secretary granules for secretion (Nillni n.p.). TRH develops from bigger inactive precursor (known as proTRH) as a result of modifications after translation and moved through the controlled secretary pathway. Prohormone convertases (abbreviated as PCs) including PC1/3 ...

The article “Endocrine System - Everything You Need to Know” by Galan, describes the endocrine system that comprises of various glands and how these glands function in regard to enabling the body to carry out various essential functions mainly related to metabolism as well as growth. According to the article, these glands usually secrete various hormones (chemical messengers) that control as well as coordinate various body activities particularly by activating the body to carry out various essential functions that are related to metabolism as well as growth. Essentially, the endocrine system comprises two main types of glands that include; ...

Dwarfism is defined as a physical disorder that is characterized by short stature and inability of a person to achieve a minimum height of 148 cm in his or her adulthood. Dwarfism has several types and various etiologies. The reasons of it might be genetic, metabolic or constitutional. Nowadays there are approximately 100 kinds of dwarfism, however none of these kinds is common because dwarfism occurs only in 0.5 to 1.5 births per 10000. In general there are two main qualifications of dwarfism. The first qualification relates to patients with short stature but proportionate and normal trunk-to-limb ratio. The ...

Abstract

This paper discusses how exercise stimulates the release of growth hormone. Older people tend to have lower levels of the hormone. As a result, mechanisms have been formulated to help deal with the deficiency which includes inducing the growth hormone into the individual’s body. This, therefore, leads to the discussion of the exact mechanism through which the growth hormone facilitates exercise, maintains growth and repair of worn out muscles or even reverses the aging process among the aged. Also, the functions of IGF-I binding proteins during exercise and its importance in aiding the release of the GH is ...

Based on the initial symptoms, the patient most likely suffers from hypothyroidism or low thyroid hormone disorder. Further clinical tests and an examination of the family’s medical history reveals that the particular disorder could be Hashimoto’s disease; also called Hashimoto thyroiditis. Hashimoto thyroiditis is classified as an autoimmune disease. In autoimmune disease, one's immune system attacks the body’s tissue specifically the thyroid gland (Skugor & Wilder, 2006, p.2). By attacking the thyroid gland, the disease reduces the gland’s ability to produce thyroid hormones of substantial quantity. This condition leads to hypothyroidism. Thyroid hormone deficiency presents with ...
