The Endocrine System consists of nine glands two of which are gonads, the ovaries and testes.
Pituitary or also known as the Hypophysis gland is located in the brain suspended for the Hypothalamus. The pituitary gland consists of the anterior pituitary and the posterior pituitary. The posterior pituitary does not produce any hormones; however the pituitary contains axons and the axon terminals of more than 10,000 neurons with cell bodies in the nuclei of the Hypothalamus. The Anterior pituitary releases hormones and suppresses hormones along with producing hormones.
The Thyroid Gland is located inferior to the larynx, it has two lobes that are located to the left and right side of the larynx and the mass that these lobes are connected by is a mass of tissue called isthmus. The Thyroid Gland produces two hormones.
The Parathyroid Glands are located on the posterior surface of the Thyroid lobes. The Parathyroid Glands produce one hormone through the chief cells within the Parathyroid Glands.
The Adrenal Glands also known as the Suprarenal Glands are located superior to each kidney. They have two structural and functional regions, they Adrenal cortex which produces steroid hormones and the adrenal medulla which produces hormones.
The pancreas is both an Endocrine Gland and an Exocrine Gland; the pancreas is located in the duodenum, which is the first part of the small intestine. The pancreas produces two hormones.
The Gonads which are located in the ovaries and the testes produce different hormones depending on which sex the gland is located in. In females the Gonads are located in the ovaries and produce two hormones. In males the Gonads are located in the testes and produce only one hormone.
The Pineal Gland is located at the roof of the brain at the third ventricle. The Pineal Gland produces one hormone and this gland is not completely understood at this time.
