Exam 18: A--Principles of Endocrinology: the Central Endocrine Glands

All hormones are synthesized by the endoplasmic reticulum-Golgi complex system.

Which class(es) of hormones is not stored in the secretory cell after being synthesized?

Complete each of the following statments. ____________________ are the bone cell types that form bones.

Identify the gonadotropic hormone(s).

Hormone secretion from the anterior pituitary gland is controlled

____ is the hypothalamic hormone that causes the anterior pituitary to release ____, thus, resulting in thyroid hormone release.

In the process of negative feedback:

Select the incorrect association.

Synergism occurs when:

In one kind of second-messenger system

All hormones are first formed as precursors, and then are pruned into active hormones.

Growth hormone

Hypophysiotropic hormones

Growth hormone promotes closure of the epiphyseal plate at adolescence.

Amines

Lipophilic hormones circulate in the blood largely bound to plasma proteins.

Complete each of the following statments. ____________________ hormones consist of a chain of specific amino acids of varying length.

Which of the following is a neurohormone?

Insulin-like growth factors are produced in most tissues, but primarily in the liver.

Negative-feedback control tends to maintain hormone levels at a relatively constant set point, whereas neuroendocrine reflexes usually produce a sudden increase in hormone secretion in response to a specific stimulus.
