What to know about the Pituitary Gland
Anatomy & Physiology II BIO144-1003B-06

It is interesting to find out about the pituitary glands in more detail. The pituitary glands are just one major part of the endocrine system. The pituitary glands secrete hormones to the bloodstream. It has two different categories, such as the anterior lobe and the posterior lobe. The anterior lobe secretes different hormones that are important to the human everyday life. Prolatin, growth hormone, adrenocorticotropic, gonadotropins and thyroid-stimulating hormone are the anterior pituitary hormones. (The Hormone Foundation, 2010) Prolatin produces milk for the newborn to feed. The growth hormone is exactly what the name implies. It stimulates growth in a child. Carbohydrates and fats regulate and balance by the secretion of the growth hormone. Adrenocrticotropic hormone (ACTH) stimulates the production of cortisol known as the stress hormone. It is significant in regulating blood pressure, diabetes, and healing. Gonadotropins include the follicle-stimulation hormone and the luteinizing hormone. They stimulate sex hormones in both the male and female for reproduction. The thyroid-stimulating hormone controls the secretion from the thyroid gland. The other category of the pituitary gland is the posterior lube. Antiduretic hormone and oxytocin are the hormones secreted in the posterior lube. The antiduretic hormone reduces water secretion by the kidneys. The oxytocin plays a role in childbirth because it stimulates the release of breast milk and the contracting of the uterus during labor. The pituitary gland has some very important functions. An excess of secretions from the hormones can cause a tumor.

A pituitary tumor occurs because excess of secretions becomes a growth and harms the regular functioning of the hormones or just too little secretes from the hormone. An excess of hormones is as bad as secretion of not enough hormones. Hypersecretion is an...
