Class 11 thyroid- The thyroid gland is a butterfly-shaped endocrine gland located in the front of your neck, just below your Adam’s apple. It’s one of the most important glands in your body, as it produces hormones that regulate many essential functions, including:
- Metabolism: The rate at which your body uses energy
- Heart rate
- Body temperature
- Growth and development
- Brain function
- Mood

Thyroid gland location
The thyroid gland produces two main hormones:
- Thyroxine (T4): This is the main thyroid hormone. It’s converted into the active form, triiodothyronine (T3), in your tissues.
- Triiodothyronine (T3): This is the active form of thyroid hormone. It affects nearly every cell in your body.
The production of thyroid hormones is controlled by another hormone called thyroid-stimulating hormone (TSH), which is produced by the pituitary gland in your brain. When the level of T3 and T4 in your blood is low, the pituitary gland releases TSH to stimulate the thyroid gland to produce more hormones. Conversely, when the level of T3 and T4 in your blood is high, the pituitary gland releases less TSH.
Here are some common thyroid disorders:
- Hyperthyroidism: This condition occurs when the thyroid gland produces too much thyroid hormone. Symptoms of hyperthyroidism can include weight loss, anxiety, insomnia, fatigue, irritability, and an increased heart rate.
- Hypothyroidism: This condition occurs when the thyroid gland doesn’t produce enough thyroid hormone. Symptoms of hypothyroidism can include weight gain, fatigue, feeling cold, dry skin, hair loss, and constipation.
- Goiter: This is an enlargement of the thyroid gland. It can be caused by a variety of factors, including iodine deficiency, Hashimoto’s thyroiditis, and Graves’ disease.
If you think you may have a thyroid problem, it’s important to see a doctor for diagnosis and treatment. A simple blood test can measure the levels of thyroid hormones in your blood. Treatment for thyroid disorders usually involves medication to regulate the production of thyroid hormones.
