Anatomy of the Endocrine System...
The endocrine system has many glands each of which has a specific function to secrete the hormones into the blood stream. The pituitary gland, thyroid gland, adrenal gland, pineal gland, pancreas, hypothalamus, parathyroid glands, and the gonads all make up the glands of this endocrine system.
The pituitary gland (top right picture) is located right under the brain where it sits in a cage like structure called the Sella Turcica. It is made of three lobes the anterior, posterior, and the internal lobes. This gland produces hormones that help control the growth, blood pressure, and metabolism of a human.
Thyroid gland is one of the largest endocrine glands in this system. It is found in the neck below the thyroid cartilage. This gland controls how quickly the body uses its energy, makes proteins, and controls how sensitive the body is to other hormones.
The adrenal gland sits at the top of the kidneys and is triangular shaped. It is responsible for releasing hormones in response to stress. Each adrenal gland has two distinct structures: adrenal cortex and inner medulla. The cortex produces cortisol, aldosterone, and androgens. The hormones for the cortex are regulated by neuroendocrine hormones that come for the pituitary gland. The medulla produces epinephrine and norepinephrine.
The pineal gland is the smallest gland in the vertebrate brain. It produces serotonin derivative melatonin which is a hormone that affects sleep patterns. This gland has many different functions in the body. Such as: Secretion of the Hormone Melatonin, Regulation of Endocrine Functions, Conversion of Nervous System Signals to Endocrine Signals, Causes of Feeling Sleepiness, and Influences Sexual Development.
The Pancreas is a glandular organ in the digestive system of the vertebrates. It produces many important hormones: insulin, glucagon, somatostatin, and pancreatic polypeptide. It features both endocrine and exocrine glands. This is made up of one million cell clusters that are named "islets of Langerhans." Which has four different cell types. Most are in contact with blood vessels.
The hypothalamus is a part of the brain that has nuclei--which hold many functions. It links to the nervous system, and endocrine system through the pituitary glands. The functions the hypothalamus holds are certain metabolic processes for the autonomic nervous system. It secrets neurohormones, that inhibit pituitary hormones. The hypothalamus controls body temperature, hunger, behavior, fatigue, and sleep cycles.
Parathyroid glands are small endocrine glands which are located in the neck. They produce parathyroid hormones. Humans have four parathyroid glands that are on the surface of thyroid glands. The job of parathyroid glands is to control the amount of calcium and blood in the bones.

It features both endocrine and exocrine glands. This is made up of one million cell clusters that are named "islets of Langerhans." Which has four different cell types. Most are in contact with blood vessels.
