The located in the throat bilobed gland connected by an isthmus is the thyroid gland. The thyroid gland is a butterfly-shaped endocrine gland that is located in the neck, just below the Adam's apple. It is an important part of the endocrine system, which produces hormones that help regulate the body's metabolism, growth, and development.

The thyroid gland is divided into two lobes, which are connected by a narrow band of tissue called the isthmus. These lobes are located on either side of the windpipe (trachea). The thyroid gland produces two main hormones: thyroxine (T4) and triiodothyronine (T3). These hormones play a vital role in the body's metabolism, as they help regulate the body's energy production and use. They also help regulate the body's growth and development, as well as the function of other organs and systems in the body.

The thyroid gland is regulated by the pituitary gland, which is located in the brain. The pituitary gland produces a hormone called thyroid-stimulating hormone (TSH), which tells the thyroid gland to produce and release its hormones. If the body's T4 and T3 levels are too low, the pituitary gland will release more TSH to stimulate the thyroid gland to produce more hormones. If the body's T4 and T3 levels are too high, the pituitary gland will release less TSH, which will cause the thyroid gland to produce and release less hormones.

Problems with the thyroid gland can lead to a number of health issues. Hypothyroidism, or an underactive thyroid, occurs when the thyroid gland does not produce enough hormones. This can lead to symptoms such as fatigue, weight gain, dry skin, and hair loss. Hyperthyroidism, or an overactive thyroid, occurs when the thyroid gland produces too many hormones. This can lead to symptoms such as weight loss, tremors, and irritability.

Overall, the located in the throat bilobed gland connected by an isthmus, or thyroid gland, is an important part of the endocrine system. It plays a vital role in regulating the body's metabolism, growth, and development, and problems with the thyroid gland can lead to a number of health issues. It is important to maintain the health of the thyroid gland through a healthy diet and lifestyle, and to seek medical attention if any problems or concerns arise.
