The endocrine system part 1

Anterior Lobe The anterior lobe of the pituitary, also called the adenohypophysis,releases several hormones Table Many of these hormones are called glycoproteins because they are made of carbohydrates and proteins. The hypothalamus controls the adenohypophysis; therefore, neural commands release these hormones. Five of these hormones the tropic hormones control the growth, development, and proper functioning of other endocrine glands.

That's because it secretes hormones into the bloodstream, and makes and secretes enzymes into the digestive tract. It links the endocrine system and nervous system. Nerve cells in the hypothalamus make chemicals that control the release of hormones secreted from the pituitary gland.

1 What is the endocrine system?

The hypothalamus gathers information sensed by the brain such as the surrounding temperature, light exposure, and feelings and sends it to the pituitary.

This information influences the hormones that the pituitary makes and releases. Despite its small size, the pituitary is often called the "master gland.

The pituitary gland makes many hormones, such as: The pituitary also secretes hormones that signal the reproductive organs to make sex hormones. The pituitary gland also controls and the menstrual cycle in women. THY-royd is in the front part of the The endocrine system part 1 neck. It's shaped like a bow tie or butterfly.

It makes the thyroid hormones thyroxine pronounced: These hormones control the rate at which cells burn fuels from food to make energy. The more thyroid hormone there is in the bloodstream, the faster chemical reactions happen in the body. Thyroid hormones are important because they help kids' and teens' bones grow and develop, and they also play a role in the development of the brain and nervous system.

Attached to the thyroid are four tiny glands that work together called the parathyroids pronounced: They release parathyroid hormone, which controls the level of calcium in the blood with the help of calcitonin pronounced: These two triangular adrenal pronounced: The adrenal glands have two parts, each of which makes a set of hormones and has a different function: The outer part is the adrenal cortex.

It makes hormones called corticosteroids pronounced: The inner part is the adrenal medulla pronounced: It makes catecholamines pronounced: Also called adrenaline, epinephrine increases blood pressure and heart rate when the body is under stress.

It secretes melatonin pronounced: The gonads are the main source of sex hormones. Most people don't realize it, but both guys and girls have gonads. In guys the male gonadsor testes pronounced: TES-teezare in the scrotum.

Human Endocrine System: MCQs Quiz - 3

The endocrine system is a chemical messenger system consisting of hormones, the group of glands of an organism that secrete those hormones directly into the circulatory system to regulate the function of distant target organs, and the feedback loops which modulate hormone release so that homeostasis is maintained.

In humans, the major endocrine glands are the thyroid gland and the adrenal glands. This article, which forms part of the life sciences series and is the first of two articles on the endocrine system, examines the structure and function of the organs of the endocrine system.
