Question

Write the names of endocrine glands found in humans.

Hint:

Mnemonic: {“3P-TAPTO”} → Pituitary, Pineal, Parathyroid, Thyroid, Adrenal, Pancreas, Thymus, Ovaries/Testes.

Answer 1

Step 1: Concept of Endocrine Glands
Endocrine glands are also called ductless glands because they do not have ducts to release their secretions. Instead, they release hormones directly into the bloodstream. These hormones regulate various body functions such as growth, metabolism, reproduction, and homeostasis.
Step 2: Names of Endocrine Glands in Humans
Pituitary gland: Known as the “master gland,” it controls other endocrine glands.
Pineal gland: Secretes melatonin which regulates sleep-wake cycles.
Thyroid gland: Produces thyroxine which controls metabolism.
Parathyroid glands: Regulate calcium and phosphate balance in the body.
Adrenal glands: Produce adrenaline and cortisol for stress response and metabolism.
Pancreas (Islets of Langerhans): Produces insulin and glucagon to regulate blood sugar.
Thymus gland: Important in early life for immunity (T-cell maturation).
Gonads (Testes in males and Ovaries in females): Produce sex hormones (testosterone, estrogen, progesterone).
Final Answer:
The main endocrine glands in humans are: Pituitary, Pineal, Thyroid, Parathyroid, Adrenal, Pancreas, Thymus, Testes, and Ovaries.
