Study Guide: Endocrine Regulation

1

The chemical messengers of the endocrine system are

1

Which of the following statements is true of the endocrine system

1

Which of the following is not an endocrine gland?

1

The neuroendocrine system performs all of the following functions except

1

Nonsteroid hormones include

1

Anabolic hormones

1

The control of hormone secretion is

1

The nervous system functions at a much greater speed than the endocrine system

1

The most widely used method of hormone classification is by chemical structure

1

Steroid hormone receptors are usually attached in the plasma membrane of a target cell

1

Production of too much hormone of a diseased gland is termed hyposecretion

1

Input from the nervous system influences secretion of hormones

1

Eicosanoids are referred to as

1

hormones are hormones that regulate activity in nearby cells within the same tissue as their source.

1

hormones regulate activity in he secreting cell itself.

1

The of the male reproductive system secretes prostaglandins in the semen.

1

Leukotrines are regulators of .

1

PGFs are required for normal to occur in the digestive tract.

1

Responses that result from the operation of feedback loops within the endocrine system are called .

1

Unused hormones circulating in the blood are excreted by the .

1

In , one hormone produces the opposite effect of another hormone.

1

In second messenger systems, the hormone-receptor complexes may be taken into the cell by means of .

1

The of steroid hormone present determines the magnitude of a target cell's response.

1

Endocrine target cells must have the appropriate receptor to be influenced by the signaling chemical - a process called ( signal transduction, signal induction ).

1

If too little hormone is produced, the condition is called ( hypersecretion, hyposecretion ).

1

Many nonsteroid hormones seem to use cAMP as the ( first messenger, second messenger ).

1

Some hormones produce their effects by triggering the opening of ( calcium, potassium ) channels.

1

The ( pituitary, parathyroid ) regulate(s) the thyroid by producing thyroid-stimulating hormone (TSH).

1

If norepinephrine diffuses into the blood and then binds to an adrenergic receptor in a distant target cell, it is known as

1

Which of the following is not a peptide

1

Combinations of hormones will have a greater effect on a target cell than the sum of the affects that each would have if acting alone. This phenomenon is called:

1

The target cell concept is an example of the ( lock-and-key, signal transduction, mobile-receptor, nuclear receptor ) model of chemical reactions.

5

Blood regulator important in blood clotting: ( Thromboxane, leukotrines, tissue hormone, eicosanoids, ibuprofen ).
Immunity regulator: ( leukotrines, Thromboxane, tissue hormone, eicosanoids, ibuprofen )
Local hormone: ( tissue hormone, Thromboxane, leukotrines, eicosanoids, ibuprofen )
Lipid Molecules: ( eicosanoids, Thromboxane, leukotrines, tissue hormone, ibuprofen )
Inhibits PGE synthesisi: ( ibuprofen, Thromboxane, leukotrines, tissue hormone, eicosanoids )

8

Binds to specific plasma membrane receptor ( Nonsteroid hormone, Steroid hormone )
Response time is usually one hour to several days ( Steroid hormone, Nonsteroid hormone )
Receptor is mobile in the cytoplasm or nucleus ( Steroid hormone, Nonsteroid hormone )
Lipis ( Steroid hormone, Nonsteroid hormone )
Regulates gene activity ( Steroid hormone, Nonsteroid hormone )
Stored in secretory vesicles before release ( Nonsteroid hormone, Steroid hormone )
One or more amino acids ( Nonsteroid hormone, Steroid hormone )
Response time is usually several seconds to a few minutes ( Nonsteroid hormone, Steroid hormone )
