Parathyroid gland: is located behind the thyroid. It secretes parathyroid hormones - PTH that regulates calcium and phosphate. Observed at labpaq website Chief cells and oxyphil cells were noted.

Thymus gland: it lies under the sternum and above the trachea in the mediastinum it secretes also thymosin. Labpaq website. Noted the medulla, cortex, and Hassall’s corpuscles from infant thymus.

Adrenal gland: Located on the top of the kidneys, it secretes epinephrine slides viewed at labpaq website it was noted connective in the capsule and next to it the adrenal cortex, adrenal medulla and cells and blood vessels.

    The pituitary gland was observed to be in 2 distinct parts and separated by a middle ridge (little ravine). I observed the gland to be composed of two tissue types, an adenohypophysis (anterior lobe) derived from buccal ectoderm and a neurohypophysis (posterior lobe) also called pars nervosa derived from neural ectoderm. The adenohypophysis contains mainly cords of glandular epithelium surrounded by blood vessels and some C.T. The major anterior portion of this lobe is called pars distalis. A smaller portion, pars intermedia, lies between the pars distalis and the posterior lobe neurohypophysis. The posterior lobe contains mainly…

    An epithelial cell in the thyroid gland, called a thyrocyte forms spherical follicles that produce a protein called thyroglobulin. This is a globular protein that has a functional role in metabolism. The protein is used by the thyroid gland to produce thyroid hormones; thyroxine (T4) is an example of one of the hormones created. Thyroxine is formed by iodine binding to tyrosine residues in thyroglobulin molecules, inside the follicle cell. (www.vivo.colostate.edu/hbooks/pathphys/endocrine/thyroid/chem.html)…

    The thyroid is located in the neck superior to the thyroid cartilage, also known as the “Adam’s apple”. It has two lobes which are joined by an isthmus. The thyroid gland has a sufficient blood supply which consists of four arteries to ensure adequate blood flow, thyroid bruit with enlargement, and “C” cells interspersed with follicular cells. The Superior thyroid artery branches off the common carotid artery and the inferior thyroid artery which branches off the Subclavian artery supply an ample amount of blood to the actual thyroid gland. The thyroid gland has not only a superior vein and a middle vein which both dumps into the internal jugular vein but also an inferior vein that branches into the subclavian vein.…

    The thyroid gland is the gland that makes and stores hormones that help regulate the heart rate, blood pressure, body temperature, and metabolism. Thyroid hormones are essential for the function of every cell in the body. They help regulate growth and the rate of chemical reactions in the body. Thyroid hormones also help children grow and develop. The thyroid gland is located in the lower part of the neck, below the Adam's apple, wrapped around the trachea. It has the shape of a butterfly with two lobes attached to one another by a middle part called the isthmus. The thyroid uses iodine, a mineral found in some foods and in iodized salt, to make its hormones. The two most important thyroid hormones are thyroxine (T4) and triiodothyronine (T3). The thyroid gland also makes the hormone calcitonin, which is involved in calcium metabolism and stimulating bone cells to add calcium to bone.…

    They are located on the cranial poles of the kidneys. The adrenals play a very large role in metabolism, behavior, and stress. These glands ave a tremendous anti-inflammatory effect on the immune system which is why horses with PPID show signs of poor immunity like chronic dermatitis, foot abscesses, and poor wound healing. The adrenal glands also produce the catecholamines, epinephrine and norepinephrine. These hormones are responsible for the “fight or flight” response when a threat is sensed. The disease of the adrenal glands is very rare. Next is the thyroid glands. The thyroid gland straddles the trachea just behind the larynx.These hormones circulate in two different forms, bound to proteins and unbound “free” hormones. Thyroid hormones act in the young horse to promote growth, organ maturation, and regulate metabolism. In all ages, thyroid hormones play a role in protein synthesis and breakdown, increase body heat production in times of prolonged cold weather, and set basal metabolic rate. Calcitonin is also regulated by the thyroid gland and is involved with calcium homeostasis between the bone and the circulation. The parathyroid glands are two sets of organs associated with the thyroid gland. The chief cells produce parathyroid hormone (PTH) whose main function is to regulate calcium levels in the body. PTH can stimulate osteoclasts to resorb bone, releasing calcium into the bloodstream. It also can act on the kidneys to retain calcium and release phosphorous into the…

    Thyroid-stimulating hormone (TH) controls the secretion of thyroid hormones and targets the thyroid gland. TH is a peptide hormone. Thyroid hormone is produced in the thyroid. It is stimulated by the thyroid-stimulating hormone from the thyroid gland and inhibition occurs when there is negative feedback from thyroid hormone. TH triggers the liver and, enters target cells by means of an energy-dependent transport system and by sending second messengers. (Martini and Nath, 2009).…
