Textbook Question

Chapter 18, Problem 1RAC

The pituitary gland
a. develops from the floor of the brain.
b. develops from the roof of the mouth.
c. is stimulated by neurohormones produced in the midbrain.
d. secretes only three major hormones.
e. Both a and b are correct.

Expert Solution & Answer

Summary Introduction

Introduction:

The pituitary gland secretes hormones that fall under two categories: posterior pituitary hormones and anterior pituitary hormones. They have varying effects on the body in several ways.

Answer to Problem 1RAC

The correct answer is option (e) Both a and b are correct.

Explanation of Solution

Explanation/justification for the correct answer:

Option (e) both a and b are correct. The posterior pituitary gland embryonically develops from an outgrowth of the hypothalamus region of the brain. Hypothalamus lies on the floor of the brain. The anterior pituitary gland develops as an outgrowth of the roof of the embryonic oral cavity. So, the correct answer is option (e).

Explanation for incorrect answer:

Option (a) develops from the floor of the brain. The posterior pituitary gland develops from the floor of the brain. However, the anterior pituitary gland develops from the roof of the oral cavity. So, this is an incorrect answer.

Option (b) develops from the roof of the mouth. The anterior pituitary gland develops from the roof of the oral cavity. However, the posterior pituitary gland develops from the floor of the brain. So, this is an incorrect answer.

Option (c) is stimulated by neurohormones produced in the midbrain. The pituitary gland is stimulated by the hypothalamus. So, this is an incorrect answer.

Option (d) secretes only three major hormones. The pituitary gland produces more than three major hormones. For example, antidiuretic hormone, oxytocin, growth hormone, TSH (thyroid stimulating hormone), and prolactin. So, this is an incorrect answer.

Conclusion

The posterior pituitary gland develops from the floor of the brain. The anterior pituitary gland develops from the roof of the oral cavity. Hence, the correct answer is option (e) Both a and b are correct.
