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.

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.

  4. Pancreas

Reveal answer Fill a bubble to check yourself
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.

Reveal answer Fill a bubble to check yourself
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.

Multiple choice
  1. hypothalamus

  2. pituitary

  3. CNS

  4. midbrain

Reveal answer Fill a bubble to check yourself
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.

Multiple choice
  1. Salivary gland - Exocrine gland

  2. Liver - Exocrine gland

  3. Thyroid gland - Endocrine gland

  4. Pancreas - Exocrine gland

  5. Adrenal - Endocrine gland

Reveal answer Fill a bubble to check yourself
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.
