The gland that secretes Oxytocin hormone is [A] Pituitary. Oxytocin is produced by the hypothalamus and then transported and stored in the posterior pituitary gland. Upon stimulation, oxytocin is released into the bloodstream. It plays vital roles in reproductive functions and social bonding. During childbirth, oxytocin stimulates uterine contractions, aiding in labor and delivery. Additionally, it facilitates milk ejection (let-down reflex) during breastfeeding by causing contraction of the myoepithelial cells surrounding mammary gland alveoli.
Oxytocin also influences social behaviors and emotional bonding, playing a role in maternal-infant attachment, romantic attachment, and trust. While the pineal gland primarily secretes melatonin to regulate sleep-wake cycles, the adrenal gland secretes hormones like cortisol and adrenaline in response to stress. The ovary secretes hormones such as estrogen and progesterone, crucial for reproductive functions and menstrual cycle regulation.
Growth hormone (GH) is secreted in the [D] Pituitary gland. Specifically, it is synthesized and released by somatotroph cells located in the anterior portion of the pituitary gland, which is situated at the base of the brain.

Growth hormone (GH) is secreted in the [D] Pituitary gland. Specifically, it is synthesized and released by somatotroph cells located in the anterior portion of the pituitary gland, which is situated at the base of the brain. GH secretion is regulated by the hypothalamus through the release of growth hormone-releasing hormone (GHRH) and somatostatin, which stimulate and inhibit GH production, respectively.
Once released, GH enters the bloodstream and exerts its effects on various tissues throughout the body. Its primary role is to stimulate growth, particularly during childhood and adolescence, by promoting the growth of bones and tissues. Additionally, GH influences metabolism, protein synthesis, and cell growth and repair in adults. Dysfunction in GH secretion or signaling can lead to growth disorders such as dwarfism or gigantism, highlighting the importance of proper regulation of GH secretion from the pituitary gland.
The endocrine hormone that stimulates the thyroid gland to secrete thyroxine is [A] TSH, or Thyroid Stimulating Hormone.

The endocrine hormone that stimulates the thyroid gland to secrete thyroxine is [A] TSH, or Thyroid Stimulating Hormone. TSH is produced by the anterior pituitary gland in response to signals from the hypothalamus. When thyroid hormone levels in the blood decrease, the hypothalamus releases thyrotropin-releasing hormone (TRH), which prompts the anterior pituitary to secrete TSH.
TSH then binds to receptors on cells in the thyroid gland, stimulating the synthesis and secretion of thyroxine (T4) and triiodothyronine (T3), collectively known as thyroid hormones.
Thyroxine plays a crucial role in regulating metabolism, growth, and development throughout the body.
In contrast, the other hormones listed—FSH (Follicle Stimulating Hormone), LTH (Lactogenic Hormone, also known as Prolactin), and ACTH (Adrenocorticotropic Hormone)—have different functions. FSH regulates reproductive processes, LTH stimulates milk production in the mammary glands, and ACTH stimulates the adrenal glands to produce cortisol. Thus, TSH specifically targets the thyroid gland to regulate thyroxine secretion.
