Which of the following glands regulates the release of the hormone testosterone?

A.

Anterior pituitary

B.

Thyroid

C.

Parathyroid

D.

Posterior pituitary

Answer and Explanation

The Correct Answer is A

A.  Anterior pituitary:
The anterior pituitary gland regulates the release of testosterone by secreting luteinizing hormone (LH. , which stimulates the Leydig cells in the testes to produce testosterone. This hormonal regulation is crucial for maintaining testosterone levels and reproductive function, making this the correct answer.

B.  Thyroid:
The thyroid gland is involved in regulating metabolism and growth through hormones such as thyroxine (T4.  and triiodothyronine (T3. . It does not directly regulate testosterone production.

C.  Parathyroid:
The parathyroid glands are responsible for regulating calcium and phosphate balance in the body through the secretion of parathyroid hormone (PTH. . They do not play a role in regulating testosterone levels.

D.  Posterior pituitary:
The posterior pituitary gland releases hormones like antidiuretic hormone (ADH.  and oxytocin, but it does not regulate testosterone production. The regulation of testosterone primarily involves the anterior pituitary gland and its secretion of LH.

Correct Answer is A

Explanation

A. Release of renin: When blood pressure decreases, the kidneys respond by releasing renin, an enzyme that initiates the renin-angiotensin-aldosterone system (RAAS. . This system increases blood pressure by causing vasoconstriction and promoting sodium and water reabsorption.

B. Decrease in sodium reabsorption: A decrease in blood pressure would typically lead to an increase, not a decrease, in sodium reabsorption. This is because the body aims to retain sodium and water to increase blood volume and pressure.

C. Constriction of the efferent arteriole: While constriction of the efferent arteriole can help increase glomerular filtration rate (GFR. in the kidneys, it is not the primary response to a decrease in blood pressure. The release of renin is the initial and more direct response.

D. Dilation of the afferent arteriole: Dilation of the afferent arteriole can help increase blood flow to the kidneys and maintain GFR, but it is part of the local autoregulatory mechanisms. The systemic response to decreased blood pressure involves the release of renin.

Correct Answer is C

Explanation

A. Eccrine:
Eccrine glands are sweat glands that are responsible for producing a watery sweat that helps regulate body temperature. They do not produce oil and are not involved in lubricating hair follicles.

B. Ceruminous:
Ceruminous glands are specialized sweat glands located in the ear canal. They produce cerumen (earwax. , which helps protect the ear from debris and microorganisms, but they do not produce oil for hair follicles.

C. Sebaceous:
Sebaceous glands are responsible for producing sebum, an oily substance that lubricates and protects hair follicles and the skin. This oil helps keep hair and skin moisturized and is the correct answer for the gland that lubricates hair follicles.

D. Apocrine:
Apocrine glands are a type of sweat gland found in specific areas such as the armpits and genital regions. They produce a thicker sweat that can contribute to body odor but do not produce oil to lubricate hair follicles.
