    Increases the production of melanin in melanocytes, thereby causing darkening of skin pigmentation.

    • Antidiuretic hormone

    • Luteinizing hormone

    • Interstitial cell-stimulating hormone

    • Melanocyte-stimulating hormone

    Correct Answer
    A. Melanocyte-stimulating hormone
    Explanation
    Melanocyte-stimulating hormone increases the production of melanin in melanocytes, which are the cells responsible for skin pigmentation. This hormone stimulates the melanocytes to produce more melanin, leading to the darkening of the skin.

    Stimulates the secretion of hormones by the thyroid gland

    • Thyroid-stimulating hormone

    • Oxytocin

    • Lactogenic hormone

    • Growth hormone

    Correct Answer
    A. Thyroid-stimulating hormone
    Explanation
    The correct answer is thyroid-stimulating hormone because it is a hormone produced by the pituitary gland that stimulates the thyroid gland to produce and release thyroid hormones. These thyroid hormones are essential for regulating the body's metabolism, growth, and development. Therefore, thyroid-stimulating hormone plays a crucial role in stimulating the secretion of hormones by the thyroid gland.

    Secreted by the hypothalamus and stored and released in the pituitary gland, helps control blood pressure by reducing the amount of water that is excreted through the kidneys

    • Oxytocin

    • Luteinizing hormone

    • Antidiuretic hormone

    • Growth hormone

    Correct Answer
    A. Antidiuretic hormone
    Explanation
    Antidiuretic hormone (ADH), also known as vasopressin, is secreted by the hypothalamus and stored and released in the pituitary gland. It helps control blood pressure by reducing the amount of water that is excreted through the kidneys. ADH acts on the kidneys to increase water reabsorption, thereby decreasing the amount of urine produced and increasing blood volume. This mechanism helps to maintain blood pressure within a normal range.

    Rate this question:

  • 5. 

    Stimulates ovulation in the female. In the male, it stimulates the secretion of testosterone.

    • Melanocyte-stimulating hormone

    • Lactogenic hormone

    • Antidiuretic hormone

    • Luteinizing hormone

    Correct Answer
    A. Luteinizing hormone
    Explanation
    Luteinizing hormone is a hormone that plays a crucial role in both males and females. In females, it stimulates ovulation, which is the release of an egg from the ovary. This hormone also helps in the development of the corpus luteum, which produces progesterone. In males, luteinizing hormone stimulates the Leydig cells in the testes to produce testosterone, an important male sex hormone. Therefore, luteinizing hormone is responsible for regulating reproductive functions in both males and females.

    Stimulates uterine contractions during childbirth

    • Interstitial cell-stimulating hormone

    • Oxytocin

    • Luteinizing hormone

    • Follicle-stimulating hormone

    Correct Answer
    A. Oxytocin
    Explanation
    Oxytocin is a hormone that stimulates uterine contractions during childbirth. It is released by the pituitary gland and plays a crucial role in initiating and regulating the labor process. Oxytocin helps to strengthen and coordinate the contractions of the uterus, allowing for the progression of labor and the eventual delivery of the baby. It also promotes the release of milk during breastfeeding and is involved in bonding and social interactions.

    Stimulates the growth and secretions of the adrenal cortex

    • Luteinizing hormone

    • Growth hormone

    • Lactogenic hormone

    • Adrenocorticotropic hormone

    Correct Answer
    A. Adrenocorticotropic hormone
    Explanation
    Adrenocorticotropic hormone (ACTH) stimulates the growth and secretions of the adrenal cortex. The adrenal cortex is responsible for producing hormones such as cortisol, which regulates metabolism and helps the body respond to stress. ACTH acts on the adrenal cortex by binding to specific receptors and triggering the release of cortisol. This hormone is essential for maintaining proper adrenal function and plays a crucial role in the body's stress response system.

    What is C pointing to? - ProProfs

    What is C pointing to?

    Correct Answer
    Adrenal glands, adrenal glands, Adrenal gland, adrenal gland
    Explanation
    C is pointing to the adrenal glands. The repetition of the phrase "adrenal glands, adrenal glands, Adrenal gland, adrenal gland" suggests that C is referring to multiple adrenal glands. The use of both uppercase and lowercase letters for "Adrenal gland" indicates that it could be a typo or inconsistency in capitalization, but it still refers to the same thing - the adrenal glands.

    Also known as prolactin, stimulates and maintains the secretion of breast milk in the mother after childbirth

    • Lactogenic hormone

    • Oxytocin

    • Luteinizing hormone

    • Adrenocorticotropic hormone

    Correct Answer
    A. Lactogenic hormone
    Explanation
    The correct answer is lactogenic hormone. Lactogenic hormone, also known as prolactin, is responsible for stimulating and maintaining the secretion of breast milk in the mother after childbirth. This hormone plays a crucial role in lactation and is produced by the pituitary gland. It helps in the development of mammary glands and the production of milk.

    Rate this question:

  • 11. 

    Stimulates the secretion of estrogen and the growth of ova in the ovaries of the female. In males, it stimulates the production of sperm in the testicles.

    • Follicle-stimulating hormone

    • Growth hormone

    • Thyroid-stimulating hormone

    • Interstitial cell-stimulating hormone

    Correct Answer
    A. Follicle-stimulating hormone
    Explanation
    Follicle-stimulating hormone (FSH) is responsible for stimulating the secretion of estrogen and the growth of ova (eggs) in the ovaries of females. In males, FSH stimulates the production of sperm in the testicles. This hormone plays a crucial role in the reproductive system of both males and females, regulating the development and maturation of reproductive cells.

    Correct Answer(s)
    A. Antidiuretic hormones
    A. Oxytocin
    Explanation
    The posterior lobe of the pituitary gland secretes antidiuretic hormones and oxytocin. Antidiuretic hormones help regulate the body's water balance by reducing the amount of urine produced. Oxytocin plays a role in childbirth and breastfeeding, as it stimulates contractions of the uterus during labor and helps with the release of breast milk.
