Analysis and explanation
In the human endocrine system, some glands are paired while others are single (unpaired):
- Pituitary gland (Option A): It is a single, unpaired gland located at the base of the brain.
- Ovary (Option B): Ovaries are paired female gonads located on either side of the lower abdomen.
- Testis (Option C): Testes are paired male gonads located inside the scrotum.
- Adrenal (Option D): Adrenal glands are a pair of glands, with one gland situated on top of each kidney.
Therefore, the pituitary gland is the one that does NOT occur as a pair.
Interesting facts
The pituitary gland is often called the 'master gland' because it secretes hormones that control the functioning of many other endocrine glands in the body.
