Question

Which of the following would not be examples of a gland functioning as part of the endocrine system?

Select all that apply.

A thyroid gland releasing thyroxin into the blood
B acinar cells of the pancreas releasing digestive enzymes into the small intestine
C sebaceous glands of the skin releasing an oily lubricant
D hypothalamus releasing TSH into the blood

Answer 1

Endocrine glands are those that release regulatory chemicals inside the body. Choices A, B, and D are examples of endocrine glands. C mentions sebaceous glands, which are found in the epidermis of the skin and secrete sebum (skin oils) onto the surface of the skin. They have no regulatory function, other than to lubricate and protect the skin. Sebaceous glands are exocrine glands, and are not part of the endocrine system.
