Lesson: The Thyroid and Parathyroid Glands Biology

In this lesson, we will learn how to describe the function of the thyroid and parathyroid glands in the human body and the symptoms of diseases associated with these glands.

Lesson Plan

Students will be able to

describe the structure of the thyroid gland and its location in the human body,
describe the structure of the parathyroid gland and its location in the human body,
recall that thyroxine is released from the thyroid gland and outline its function in regulating metabolic rate, maintaining heart rate and blood pressure, and supporting normal growth,
recall that calcitonin is released from the thyroid gland and outline its function in decreasing calcium levels in the blood,
recall that parathyroid hormone is released from the parathyroid gland to increase calcium levels in the blood,
outline the complications and health problems associated with oversecretion or undersecretion of the thyroid and parathyroid hormones.

Lesson Worksheet

Q1:

For the following symptoms, state which condition (hypoparathyroidism or hyperparathyroidism) is being described.

This condition causes the bones to lose mass and to be susceptible to bending and fracturing.

This condition can overexcite the nervous system and lead to painful convulsions and muscle spasms.

Q2:

What hormone is produced by the thyroid gland to decrease calcium levels in the blood?

Q3:

Which of the following is not one of the primary functions of thyroxine in the human body?
