Endocrine system
The Endocrine system is very important to our body. This system regulates our mood, growth, metabolism, tissue development, sexual functions and reproductive process. It is a very complex system with many different hormones and glands. I am going to write about the pituitary gland and thyroid. The pituitary gland is very often considered to be the most important glad in the Endocrine system. The Thyroid produces thyroxine andtriiodothyronine.
The Pituitary gland is no bigger than a pea and is round. It is located in the brain in a small bony cavity. The gland is often referred to as the master gland since it plays such a large roll in the Endocrine system. The production of pituitary hormones can be influenced by many different things. Emotions and changes of seasons are influenced because the hypothalamus provides information that the brain senses and transfers it to the pituitary.
The gland is divided into two different sections. There is the anterior lobe and posterior lobe. The anterior lobe regulates the thyroid, adrenals, and reproductive glands. The anterior lobe also produces many important hormones. It produces the growth hormone which stimulates growth of the bones and other body’s tissues. It also produces prolactin which allows women to provide milk to breastfeed when their pregnant. Thyrotropin is also produced by the anterior lobe. This hormone stimulates the thyroid gland to produce its hormones. Coricotropin is a hormone that stimulates the adrenal gland and allows it to produce different hormones.
The posterior lobe is also very important to the Pituitary gland. This area of the Pituitary gland releases antiduretic hormone. This hormone helps control the balance of water in the body. The posterior lobe also reduces oxytocin. This is important for woman when they are having a baby. The oxytocin triggers the contractions of the uterus in the woman when she is having the child.
The thyroid is located in the front of the lower neck. It is shaped like a bow tie. The hormones it releases control the rate at which cells burn fuels from food to produce energy. The production and release of these hormones is controlled by the thyrotopin, which is part of the pituitary gland. This is important because the more of this in a persons bloodstream the faster the chemical reactions in the body will occur.
