Exam 5: Principles of Endocrinology: The Central Endocrine Glands

The SCN is located in the ____________________ of the brain.

Which of these statements describes hormones

The posterior pituitary secretes ____________________ and ____________________.

Which class of hormones triggers the synthesis of new intracellular proteins within the target cell

Clock proteins are essential for controlling circadian rhythms.

There are no known growth-related signals that influence growth hormone secretion.

Match the systems, labelled a. through c. with their characteristics. (Options may be used more than once or not at all.) -Specificity is dependent on specificity of target-cell receptors.

Which of these substances is NOT associated with the post-receptor events of hydrophilic hormones

FSH and LH are collectively called ____________________ because they control secretion of sex hormones.

Most endocrine control systems involve ____________________ and hormonal components.

Hyperplasia is an increase in the number of ____________________ in a structure.

Only hormones that are not bound to plasma proteins are biologically active.

The thyroid hormone produces growth-promoting effects directly.

Each anterior pituitary hormone is controlled by a single hypophysiotropic hormone from the hypothalamus.

Hypophysiotropic hormones are secreted into the systemic circulatory system.

Growth hormone does not directly affect bone growth, but instead stimulates the release of somatomedins from the liver, which in turn promote bone growth.

Match posterior and anterior pituitary, labelled a. through c., with their features. (Options may be used more than once or not at all.) -may be directly inhibited by negative feedback from its target organ

Tropic hormones target only other glands.

The ____________________ carries hypophysiotropic hormones from the hypothalamus to the anterior pituitary.

FSH has different functions in men and women.
