Briefly identify and describe the hormones produced by "master gland" found in Figure 27.1 and the target organs in which they exert their effects (Figure 27.2).

The pituitary gland is located in the sella turcica of the sphenoid bone. It consists of two large functional lobes, the adenohypophysis and the neurohypophysis and consisting of the posterior pituitary and infundibulum. The anterior pituitary produces and secretes a number of hormones. Four of them are tropic hormones. The anterior pituitary controls the activity of many other endocrine glands and that's why it is referred to as the master gland. The posterior pituitary is not an endocrine gland because it does not synthesize the hormones it releases them.

Its major endocrine product is melatonin, which exhibits a diurnal (daily) cycle. It peaks at night, making us drowsy, and is lowest around noon.

The thyroid gland is composed of two lobes joined by a central mass, or isthmus. It is located in the throat, just inferior to the larynx. It produces two major hormones, thyroid hormone and calcitonin.

The parathyroid glands are found embedded in the posterior surface of the thyroid gland. Typically, there are two small oval glands on each lobe, but there may be more and some may be located in other regions of the neck.

The thymus is a bilobed gland situated in the superior thorax, posterior to the sternum and anterior to the heart and lungs.

The two adrenal, or suprarenal, glands are located atop or close to the kidneys. Anatomically, theadrenal medulla develops from neural crest tissue, and it is directly controlled by the sympathetic nervous …show more content…
The thyroid gland is an organ that produces hormones to enhance metabolism in the body.

Unlike gastrointestinal or kidney disorders, many people do not quite have a clear idea about "thyroid disorders." In which part of the body is the thyroid gland found? What is its function? Let's first take a look at the location and function of the thyroid gland in order to understand thyroid disorders.

The parathyroid glands are four tiny glands, located in the neck, that control the body's calcium levels. Each gland is about the size of a grain of rice (weighs approximately 30 milligrams and is 3-4 millimeters in diameter).

The pancreas is really two glands that are intimately mixed together into one organ. The bulk of the pancreas is composed of “exocrine” cells that produce enzymes to help with the digestion of food. These exocrine cells release their enzymes into a series of progressively larger tubes (called ducts) that eventually join together to form the main pancreatic duct. The second functional component of the pancreas is the "endocrine" pancreas. The endocrine pancreas is composed of small islands of cells, called the islets of

The thyroid gland is a vital part of the endocrine system in the human body. It is directed at maintaining homeostasis and controlling basal metabolic rate. The thyroid is in the neck below the larynx forming a bow-tie shape around the trachea. This gland secretes thyroid hormones and has influence on almost every organ in the human body. In addition, the thyroid gland develops from endoderm and is associated with the pharyngeal gut. This gland is also highly vascularized to aid in circulation of…

Thyroid Gland Research Paper

Thyroid gland is a small butterfly shaped organ which is located in the neck. This is an endocrine gland which produces, stores and secrets two very important hormones T3 (triiodothyronine) and T4 (thyroxine). These hormones are chemical messengers for various cellular functions and mainly regulate the metabolism and energy consumption of the body, affecting all body organs and systems. Does Thyroid Affect Pregnancy? It is very important to understand the proper function of thyroid gland to understand…
