A pair of endocrine glands located in the human brain is:
Step 1: Understanding the function of the glands.
- The Hypothalamus is located in the brain and regulates many bodily functions, including hormone release.
- The Pineal gland is also located in the brain and is responsible for regulating sleep-wake cycles by releasing melatonin.
Step 2: Analyzing the options.
- Option (A) includes Parathyroid, which is not located in the brain, so it is incorrect.
- Option (B) includes Thymus, which is located in the chest, not the brain, so it is incorrect.
- Option (C) includes Thymus again, so it is also incorrect.
- Option (D) is correct, as both the Hypothalamus and Pineal gland are located in the brain.
