Endocrine and Exocrine Glands Questions
-
Pineal gland
-
Plasma
-
Nodule
-
Lymph node
A
Correct answer
Explanation
The pineal gland, a small endocrine gland in the vertebrate brain, is widely recognized in human anatomy as the smallest organ in the human body. Lymph nodes and other listed items vary in size and are generally larger.
-
Puny gland
-
Master gland
-
Pleasure gland
-
Major gland
B
Correct answer
Explanation
The pituitary gland is called the 'master gland' because it produces hormones that regulate other endocrine glands in the body. Puny gland and pleasure gland are made-up terms, while major gland is not a recognized alternative name.

Lachrymal
-
Pituitary
-
Thyroid
-
Pancreas
A
Correct answer
Explanation
The lacrimal glands (also called lachrymal glands) are the specialized glands that produce tears. They are located above each eye and secrete the watery layer of tears that keeps eyes moist and contains enzymes to protect against infection. Other listed glands have different functions.

Thyroid
-
Pituitary
-
Spleen
C
Correct answer
Explanation
The pituitary gland is called the master gland because it controls other endocrine glands through hormone secretion. It produces hormones that regulate growth, metabolism, reproduction, and stress response. The hypothalamus influences the pituitary, but the pituitary directly regulates other glands like thyroid, adrenals, and gonads.

Dermatologist
-
Nephrologist
A
Correct answer
Explanation
An endocrinologist specializes in disorders of the endocrine system, which includes ductless (endocrine) glands like the thyroid, pituitary, and adrenal glands. These glands release hormones directly into the bloodstream.
-
Pancreas
-
Thyroid
-
Pituitary
-
Spleen
C
Correct answer
Explanation
The pituitary gland is called the 'master gland' because it secretes hormones that regulate other endocrine glands, including the thyroid, adrenals, and reproductive glands. The pancreas produces insulin and digestive enzymes, the thyroid regulates metabolism, and the spleen is part of the immune system.
-
Lachrymal
-
Pituitary
-
Thyroid
-
Pancreas
A
Correct answer
Explanation
Lachrymal glands, also called lacrimal glands, are located above each eye and secrete tears to lubricate and protect the eyes. The pituitary is the master gland regulating hormones, thyroid regulates metabolism, and pancreas produces digestive enzymes and insulin - none produce tears.
-
Thyroid
-
Liver
-
Pancreas
-
None of these
B
Correct answer
Explanation
The liver is the largest internal gland and largest internal organ in the human body, weighing about 1.5 kg. It performs vital functions including detoxification, protein synthesis, and bile production. The thyroid and pancreas are much smaller endocrine glands.
-
Pancreas
-
Thyroid
-
Pituitary
-
Spleen
C
Correct answer
Explanation
The pituitary gland is called the master gland because it secretes hormones that control other endocrine glands, including thyroid, adrenal glands, and reproductive glands. The pancreas regulates blood sugar, thyroid regulates metabolism, and spleen is part of the immune system - none control other glands.
-
hypothalamus
-
pituitary
-
CNS
-
midbrain
A
Correct answer
Explanation
The hypothalamus is the bridge between the nervous system and endocrine system. It produces hormones that regulate the pituitary gland, which then controls other endocrine glands. The pituitary is often called the 'master gland,' but it's actually controlled by the hypothalamus.
-
Pituitary
-
Pancreas
-
Adrenal
-
Thyroid
-
Gonads
B
Correct answer
Explanation
Pancreas is exocrine as well as endocrine gland. It is also known as mixed gland.
-
Salivary gland - Exocrine gland
-
Liver - Exocrine gland
-
Thyroid gland - Endocrine gland
-
Pancreas - Exocrine gland
-
Adrenal - Endocrine gland
D
Correct answer
Explanation
The correct pair is pancreas, which is a heterocrine gland because it serves the purpose of both the endocrine as well as exocrine gland.
