Endocrine System and Hormones Quiz

Which gland is part of the brain and is important in regulating other endocrine glands?

What type of function does the pancreas perform as an endocrine organ?

What is a possible symptom of hypothyroidism?

Which part of the body releases oxytocin and growth hormone?

What is the function of hormones when they bind to specific target cells?

Which of the following is NOT a major endocrine gland?

What is the primary function of the hypothalamus-pituitary complex?

Which of the following is NOT a location of a major endocrine gland?

Which gland is responsible for controlling the fight or flight response?

What is a possible symptom of hypothyroidism, a disorder caused by an underactive thyroid gland?

Hormones are important signaling molecules secreted by glands in the endocrine system, without ducts to carry them away, unlike exocrine glands.
Major endocrine glands include those in the brain (hypothalamus, pineal gland, pituitary gland), neck (thyroid, parathyroid), upper chest (thymus), above the kidneys (adrenal glands), near the stomach (pancreas), and gonads (ovaries and testes).
Glands may have both endocrine and exocrine functions, like the pancreas which releases insulin as an endocrine function and pancreatic enzymes as an exocrine function.
Different classes of hormones can be derived from biomolecules like amino acids, polypeptides, or lipids, influencing their structure and function.
Hormones bind to specific target cells and elicit various responses like increasing mitosis rate or preparing enzymes for action.
The hypothalamus-pituitary complex is crucial in regulating many other endocrine glands, with the pituitary gland secreting hormones like oxytocin and growth hormone.
Disorders like hypothyroidism can result from underactive glands like the thyroid, leading to symptoms like extreme fatigue and a slowed heart rate due to insufficient production of thyroid hormones.

Test your knowledge on the endocrine system and hormones, which are important signaling molecules produced by glands without ducts for transport. Learn about major endocrine glands like the hypothalamus, thyroid, adrenal glands, and more, as well as the functions of different classes of hormones and the role of the hypothalamus-pituitary complex.
