FIGURE 36.1 Label the major endocrine gladds.
To determine:
The endocrine glands in the given figure.
Introduction :
The glands of the endocrine system are termed as the endocrine glands. These glands secrete their secretions (hormones) directly into the blood, without the use of any kind of ducts. The glands included in the endocrine system are the pituitary glands, testes, ovaries, thyroid glands, parathyroid glands, adrenal glands, pineal glands, and pancreas.
Explanation of Solution
The endocrine glands in the given figure are labeled as follows:
- Hypothalamus − It is small portion of the brain that is located at the brain’s base, near the pituitary gland. Its main function is to regulate body temperature.
- Pituitary gland - Pituitary gland is present in sella turcica of sphenoid bone. This gland is also termed as the master gland as the hormones released by this gland affect the metabolism, growth, sexuality, development, and reproduction of the body.
- Testis - Testes are the paired glands and are the important male reproductive organ that produces spermatozoa and androgens.
- Pineal gland − It is an endocrine gland found in the brain. It secrets melatonin that regulates the sleep-wake cycles in humans.
- Thyroid gland - Thyroid gland is the ductless gland located in the neck region. It produces thyroxine hormone. Thyroid stimulating hormone or thyrotropic hormone is a glycoprotein that stimulates the thyroid gland to secrete thyroxine (T4) hormone and then triiodothyronine hormone (T3).
- Thymus - Thymus is located in mediastinum and thoracic cavity of neck. In adolescent, it helps in the development of immune system.
- Adrenal gland - Adrenal glands are triangular shaped glands that are present at the top of both the kidneys. The adrenal cortex is the outermost portion of this gland. The adrenal medulla is the innermost portion of the adrenal gland that secretes flight and fight hormones, epinephrine and norepinephrine.
- Pancreas - The pancreas is located at the back of the stomach and behind the stomach. It functions as an endocrine gland and as well as an exocrine gland. Many enzymes and juices are secreted by the enzymes during the digestive process. The two important enzymes of this gland are insulin and glucagon.
- Ovary − It is an organ found in the reproductive system of the females to produce ovum.
The endocrine glands in the given figure are labeled as follows:
