Psychology- Endocrine System

pineal gland

one hormone that is produced by this gland: melatonin. Melatonin may stop the action of the hormones that produce gonadotropin, which causes the ovaries and testes to develop and function. It may also help to control sleep patterns.

adrenal glands

one on top of each kidney. the adrenal glands have two parts. produces catecholamines, such as epinephrine. Also called adrenaline, epinephrine increases blood pressure and heart rate when the body experiences stress.

pancreas

part of the body's hormone-secreting system, even though it is also associated with the digestive system because it produces and secretes digestive enzymes. The pancreas produces two important hormones, insulin and glucagon. They work together to maintain a steady level of glucose, or sugar, in the blood and to keep the body supplied with fuel to produce and maintain stores of energy.

gonads

the main source of sex hormones. testes, are located in the scrotum. They secrete hormones such as testosterone.ovaries, are located in her pelvis. They produce eggs and secrete the female hormones estrogen.

Thyroid

The thyroid is a small gland inside the neck, located in front of the breathing airway and below the Adam's apple. The thyroid hormones control metabolism, which is the body's ability to break down food and store it as energy and the ability to break down food into waste products with a release of energy in the process. The thyroid produces two hormones, T3 and T4.

parathyroids

They releases a hormone, which regulates the level of calcium in the blood with the help of calcitonin.

hypothalamus

a collection of specialized cells that is located in the lower central part of the brain. Nerve cells in the hypothalamus control the pituitary gland by producing chemicals that either stimulate or suppress hormone secretions from the pituitary.

pituitary gland

located at the base of the brain just beneath the hypothalamus, is considered the most important part of the endocrine system. It's often called the "master gland" because it makes hormones that control several other endocrine glands.

thyroid

located in the front part of the lower neck, is shaped like a bow tie or butterfly and produces the thyroid hormones thyroxine and triiodothyronine. These hormones control the rate at which cells burn fuels from food to produce energy.
