The largest endocrine gland in the body is the Thyroid gland. Situated in the neck, just below the Adam’s apple, it comprises two lobes connected by a narrow isthmus. The thyroid gland produces thyroid hormones, primarily thyroxine (T4) and triiodothyronine (T3), which regulate metabolism, growth, and development. These hormones influence almost every cell in the body and play crucial roles in processes such as energy production, protein synthesis, and maintenance of body temperature.
The thyroid gland is responsible for maintaining the body’s overall metabolic rate and is involved in regulating various physiological functions, including heart rate, digestion, and muscle control. Its large size reflects its importance in the endocrine system and overall health.

The endocrine gland that can function independently of the pituitary gland is Adrenal. The adrenal glands, situated atop each kidney, have two distinct regions: the adrenal cortex and the adrenal medulla. The adrenal cortex produces steroid hormones such as cortisol, aldosterone, and sex hormones (androgens). These hormones regulate metabolism, electrolyte balance, and reproductive functions, respectively. The secretion of adrenal cortex hormones is primarily regulated by factors such as stress, blood pressure, and electrolyte levels, rather than direct control from the pituitary gland.
While the pituitary gland does influence the adrenal glands through the secretion of adrenocorticotropic hormone (ACTH), which stimulates cortisol production, the adrenal glands can still function independently to some extent. In situations of stress, the adrenal glands can respond directly to stressors by releasing hormones without requiring signals from the pituitary gland, demonstrating their ability to function autonomously.

The correct answer is [C] Insulin. Insulin is often referred to as the pacemaker of the endocrine system due to its pivotal role in regulating blood sugar levels and metabolism. Produced by the beta cells of the pancreas, insulin facilitates the uptake of glucose by cells throughout the body, where it is utilized for energy production or stored for later use.
Maintaining blood glucose within a narrow range is crucial for proper functioning of organs and tissues. Insulin helps to lower blood glucose levels by promoting glucose uptake by cells, inhibiting glucose production in the liver, and facilitating the storage of excess glucose as glycogen.
Imbalances in insulin production or function can lead to various metabolic disorders, such as diabetes mellitus, where either insufficient insulin is produced (Type 1 diabetes) or cells become resistant to insulin’s effects (Type 2 diabetes). This underscores the fundamental role of insulin as the pacemaker orchestrating metabolic processes within the body.

Myxoedema, a condition characterized by severe hypothyroidism, occurs due to dysfunction of the [D] Thyroid gland. The thyroid gland, located in the neck, produces hormones crucial for regulating metabolism, energy levels, and various bodily functions. When the thyroid gland fails to produce an adequate amount of thyroid hormones, it results in hypothyroidism.
Myxoedema presents as swelling of the skin, particularly around the face, hands, and feet, along with other symptoms such as fatigue, weight gain, hair loss, dry skin, and intolerance to cold temperatures. These symptoms arise because thyroid hormones play a vital role in regulating metabolic processes throughout the body. Without sufficient thyroid hormone levels, metabolism slows down, leading to a cascade of symptoms characteristic of hypothyroidism.
Therefore, dysfunction of the thyroid gland, specifically its inability to produce adequate levels of thyroid hormones, is the underlying cause of myxoedema in the human body.

Enlargement of the [A] Thyroid gland occurs in Goitre, a disease caused by iodine deficiency. The thyroid gland requires iodine to produce thyroid hormones, essential for regulating metabolism. In iodine-deficient regions, the thyroid enlarges in an attempt to trap more iodine from the bloodstream, resulting in the characteristic swelling known as goitre.
Despite the enlargement, the thyroid gland’s hormone production may remain inadequate due to insufficient iodine availability, leading to hypothyroidism. This condition can manifest as fatigue, weight gain, cold intolerance, and other symptoms associated with thyroid hormone deficiency.
Treatment for goitre often involves iodine supplementation, which helps restore thyroid hormone production and reduces gland enlargement. In severe cases, additional thyroid hormone replacement therapy may be necessary to address hypothyroidism. However, prevention through dietary iodine intake, such as through iodized salt or iodine-rich foods, remains the most effective strategy to combat goitre caused by iodine deficiency.
