Where is the thyroid produced and what is the target organs what is the normal function?
The thyroid gland located in front of the neck below the Adams apple, produces the thyroid hormone. It targets most tissues. The function of the thyroid hormone (TRH) is to increase the metabolic rate. This leads to an increase in oxygen and heart rate, stimulates appetite increase breakdown of nutrients and promote growth. Production of the thyroid hormone is controlled by thyroid stimulating hormone (TSH) which is secreted by the pituitary gland in response to the stimulation from the hypothalamic in the brain .Thyroid needs iodine in order to produce thyroid hormone. There are 2 primary thyroid hormones T3 (thyroxine) and T4 (tretraidothyronine).
How is the secretion of this hormone regulated?

Most of the impact is because of the stimulation of the cyclic adenosine monophosphate.
Identify one other hormone that acts in concert with assigned hormone?
TSH and parathyroid hormone is an antagonistic for blood calcium level The thyroid gland contains nests of C (clear) cells this cells react when calcium blood level are high by secreting the hormone
The pituitary gland coordinates growth and blood pressure. It coordinates with the hypothalamus to maintain homeostasis in the body. Pons: The pons sends messages from the front half of the brain to the cerebellum.
An unbalance in these hormones would cause changes in the function and structure of the gland. In the setting where there isn’t a sufficient amount of Thyroxin synthesized by the gland, there is an increase in TSH production. Over production of TSH causes hyperplasia of the gland just to match normal thyroid levels. This would then cause a goiter to form. When the goiter is grown significantly, pressure is put on the esophagus and trachea, causing respiratory
As soon as the melatonin produced, it is released into the circulation. The pineal gland is therefore without the storage function as genuine hormonal glands have. Long-term intake of melatonin does not result in any reduction of tallkottkörtels production, which is the rule for genuine hormones. - Melatonin is found in all living organisms, in greater amounts in many foods. During the intake of these are melatonin in the body.
This hormone is released by the pituitary gland and acts on the thyroid gland controlling the release of hormones by the thyroid. If someone has low thyroid levels they can experience low energy levels and depression. These are two symptoms experienced by Eric between the ages of 11 and 15. Eric became sluggish at little league and introverted showing signs of depression. The thyroid also regulates the amount of calcium in the blood and bones via Calcitonin.
What is the endocrine gland? What role does the pituitary gland have associated with the endocrine gland? Why is their negative feedback when the pituitary gland is controlling the action of another endocrine gland? Knowing and understanding the role of the pituitary gland will help you infer the negative feedback involved with the pituitary gland when controlling the action of another endocrine gland. Endocrine glands are hormonal glands that are part of the endocrine system (body's main system for controlling, organizing, and communicating the body's work), which release hormones straight into the body's bloodstream (Biology.OpenStax.1480).
By acting in different parts of the body, hormone and its derivatives, such as dihydrotestosterone, determine secondary sexual characteristics (hair growth on the face and body, a deep voice, a thick skin, the possibility of baldness, more developed musculature). During puberty, hormonal change is characterized by the appearance of acne, a jump in the overall physical development and an increase of male sex organs. Normally, for the adult male, the hormone testosterone ranges from 4 to 9 mg per day. What does restrain the increase of testosterone level? Firstly, it is the alcohol, which lowers the male sex hormone synthesis.
INTRODUCTION The pituitary gland is a central endocrine organ that regulates basic physiological functions incuding growth, reproduction and metabolic homeostasis. It situates at the base of the brain, under the optic chiasm, inside a depression on the upper surface of the sphenoid bone, the sella turcica1 (Fig.1). Fig. 1
Some forms of TBII mimic the action of TSH and stimulate the secretion of thyroid hormones, whereas other forms inhibit thyroid cell function. c) Thyroid growth-stimulating immunoglobulins They are directed against TSH receptors and stimulate the growth of thyroid follicular epithelium. 2)
The human growth hormone is naturally developed hormones by the pituitary gland. It strengthens the muscles, resulting in the loss of belly fat. This is done through cell regeneration and growth. It maintains the health of human body tissues, including the tissues of the vital organs and the brain.
The article, "Vitamin A", is written by Susan Sullivan, who is the associate director of the University of Maine. Vitamin A is a major nutrient associated with healthy skin and eyes, growth, and immune system function. It is essential for reproduction and the growth of children. Ms. Sullivan writes about the different forms, symptoms of deficiency, toxicity, and the history of vitamin A. The article main purpose is to provide information on the importance of vitamin A to your body if you follow the United States National Academy of Medicine's recommendation of dietary allowance.
Fibroblast The fibroblast is the large cell type of the dermis. These cells are responcible for the formation of procollagen and elastic fibers. Procollagen is terminally cleaved by proteolytic enzymes into collagen which aggregates and turned into cross-linked. These tightly cross-linked collagen fibers allow tensile strength and resistance to shear and other mechanical forces.(9,10)

INTRODUCTION Melatonin also known as N-acetyl-5-methoxy tryptamine is an indolic hormone produced by the Pineal Gland in animals [1]. Production of melatonin is regulated by photoperiod as its synthesis and secretion are repressed by light but induced at night in response to darkness [2].In humans it has been seen that a rise in synthesis of melatonin happens during night and vice versa during day, a circadian pattern. Moreover the mammalian “master circadian clock” located in the suprachiasmatic nucleus (SCN) of the hypothalamus provides environmental and biological timing information to the rest of the body so that physiology and behavior are coordinated for optimal functioning relative to the time of day [3]. On the basis of photic and
The endocrine system is such an important system to the body because it functions the bodies use of hormones. The body uses many different hormones and the endocrine system regulates these. When the glands of the endocrine system secrete the hormones, the hormones are put into the bloodstream to be sent to the different parts of the body. The glands that comprise the endocrine system are the hypothalamus, the pituitary gland, and the pineal gland which are all located in the brain, the thyroid, parathyroid, and thymus which are located in the throat, the adrenals and pancreas which are located in the body’s midsection, and the ovaries (female) and testes (male) which are located in the pelvic region. The system is so important because it regulates the body’s metabolism, growth and sexual development, digestion, heart rate, and many of the other body functions regulated by hormones.
INTRODUCTION Severe thyroid dysfunction may mimic almost any psychiatric symptom profile.1, 2 even before the determination of serum thyroid hormone concentrations and before suppressive and substitutive thyroid therapies became widely available, and there are reports about psychopathological syndromes associated with thyroid dysfunction such as “myxoedematous madness. ”1 Mild or latent thyroid dysfunction may be associated with more or less subtle psychiatric abnormalities.3 The prevalence of depression, anxiety disorders including panic disorder, simple phobia and obsessive-compulsive disorders is much higher in thyroid patients when compared to the general population. This suggests that the co-occurrence of psychiatric and thyroid diseases
