Question

Select out of the following a gland which does NOT occur as a pair in the human body:

• A. Pituitary
• B. Ovary
• C. Testis
• D. Adrenal

Answer 1

The Correct Option is A

The human body contains several glands, some of which occur in pairs while others are singular. The options provided include:

• Pituitary
• Ovary
• Testis
• Adrenal

To determine which gland does not occur as a pair, we need to evaluate each one:

1. Pituitary Gland: This gland is located at the base of the brain and is a single gland, not paired. It plays a critical role in hormone production and regulation.
2. Ovary: In females, ovaries come in pairs. They are responsible for producing eggs and female hormones.
3. Testis: In males, testes are paired organs located in the scrotum, responsible for producing sperm and male hormones.
4. Adrenal Gland: These glands are located above each kidney, making them a pair. They produce various hormones including adrenaline and cortisol.

Through this analysis, it is evident that the pituitary gland is the only gland that is not paired. Therefore, the correct answer is:

Pituitary
