Correct Answer
C. PosteriorExplanation
The posterior lobe of the pituitary gland controls neurohormones. This lobe is responsible for releasing hormones such as oxytocin and antidiuretic hormone (ADH), which are produced by the hypothalamus and stored in the posterior pituitary gland. These hormones play a crucial role in regulating various bodily functions, including water balance, childbirth, and breastfeeding.Rate this question:

Stimulates the growth and secretions of the adrenal cortex
- A.
Luteinizing hormone
- B.
Growth hormone
- C.
Lactogenic hormone
- D.
Adrenocorticotropic hormone
Correct Answer
D. Adrenocorticotropic hormoneExplanation
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.Rate this question:

Correct Answer
A. Follicle-stimulating hormoneExplanation
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.Rate this question:

Stimulates ovulation in females. In the male, it stimulates the secretion of testosterone.
- A.
Follicle-stimulating hormone
- B.
Melanocyte-stimulating hormone
- C.
Interstitial cell-stimulating hormone
- D.
Thyroid-stimulating hormone
Correct Answer
C. Interstitial cell-stimulating hormoneExplanation
Interstitial cell-stimulating hormone stimulates the secretion of testosterone in males. This hormone is produced by the anterior pituitary gland and plays a crucial role in the regulation of reproductive functions in males. Testosterone is responsible for the development and maintenance of male reproductive organs and secondary sexual characteristics. Therefore, interstitial cell-stimulating hormone is essential for male reproductive health and function.Rate this question:

Also known as prolactin, stimulates and maintains the secretion of breast milk in the mother after childbirth
- A.
Lactogenic hormone
- B.
Oxytocin
- C.
Luteinizing hormone
- D.
Adrenocorticotropic hormone
Correct Answer
A. Lactogenic hormoneExplanation
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:

Stimulates ovulation in the female. In the male, it stimulates the secretion of testosterone.
- A.
Melanocyte-stimulating hormone
- B.
Lactogenic hormone
- C.
Antidiuretic hormone
- D.
Luteinizing hormone
Correct Answer
D. Luteinizing hormoneExplanation
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.Rate this question:

Increases the production of melanin in melanocytes, thereby causing darkening of skin pigmentation.
- A.
Antidiuretic hormone
- B.
Luteinizing hormone
- C.
Interstitial cell-stimulating hormone
- D.
Melanocyte-stimulating hormone
Correct Answer
D. Melanocyte-stimulating hormoneExplanation
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.Rate this question:

Stimulates the secretion of hormones by the thyroid gland
- A.
Thyroid-stimulating hormone
- B.
Oxytocin
- C.
Lactogenic hormone
- D.
Growth hormone
Correct Answer
A. Thyroid-stimulating hormoneExplanation
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.Rate this question:

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
- A.
Oxytocin
- B.
Luteinizing hormone
- C.
Antidiuretic hormone
- D.
Growth hormone
Correct Answer
C. Antidiuretic hormoneExplanation
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:

Stimulates uterine contractions during childbirth
- A.
Interstitial cell-stimulating hormone
- B.
Oxytocin
- C.
Luteinizing hormone
- D.
Follicle-stimulating hormone
Correct Answer
B. OxytocinExplanation
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.Rate this question:
