Answer:
The thyroid gland is in the lower part of the front of the neck, just in front of your windpipe. It is shaped like a butterfly, with a “lobe” on each side joined by a thin strip of tissue. The nerves that control your vocal cords are just behind the thyroid.
You cannot usually see or feel the thyroid gland. But if it becomes enlarged, it causes a swelling in the neck called a goiter. Other thyroid conditions may not cause a visible goiter.
The thyroid produces important hormones called thyroxine and T3. These hormones control your metabolism – in other words, how your body gets energy from the foods you eat. If your thyroid is not working well, your body uses energy more slowly or quickly than it should.
If your thyroid is not active enough, it is called hypothyroidism. Hypothyroidism can make you gain weight, feel tired, and struggle with cold temperatures. If your thyroid is too active (hyperthyroidism), you will have more thyroid hormones than your body needs. Hyperthyroidism causes you to lose weight, speeds up your heart rate, and makes you very sensitive to heat.
Explanation:
The thyroid gland, or simply the thyroid, is an endocrine gland in the neck, consisting of two lobes connected by an isthmus. It is found at the front of the neck, below the Adam's apple. The thyroid gland secretes three hormones, namely the two thyroid hormones (thyroxine/T4 and triiodothyronine/T3), and calcitonin. The thyroid hormones primarily influence the metabolic rate and protein synthesis, but they also have many other effects, including effects on development. Calcitonin plays a role in calcium homeostasis.
