Study Guide: Endocrine Regulation

The chemical messengers of the endocrine system are

Which of the following statements is true of the endocrine system

Which of the following is not an endocrine gland?

The neuroendocrine system performs all of the following functions except

Nonsteroid hormones include

Anabolic hormones

The control of hormone secretion is

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

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

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

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

Input from the nervous system influences secretion of hormones

Eicosanoids are referred to as

[blank_start]Paracrine[blank_end] hormones are hormones that regulate activity in nearby cells within the same tissue as their source.

[blank_start]Autocrine[blank_end] hormones regulate activity in he secreting cell itself.

The [blank_start]seminal[blank_end] [blank_start]vescicles[blank_end] of the male reproductive system secretes prostaglandins in the semen.

Leukotrines are regulators of [blank_start]immunity[blank_end].

PGFs are required for normal [blank_start]peristalsis[blank_end] to occur in the digestive tract.

Responses that result from the operation of feedback loops within the endocrine system are called [blank_start]endocrine[blank_end] [blank_start]reflexes[blank_end].

Unused hormones circulating in the blood are excreted by the [blank_start]kidneys[blank_end].

In [blank_start]antagonism[blank_end], one hormone produces the opposite effect of another hormone.

In second messenger systems, the hormone-receptor complexes may be taken into the cell by means of [blank_start]endocytosis[blank_end].

The [blank_start]amount[blank_end] of steroid hormone present determines the magnitude of a target cell's response.

Endocrine target cells must have the appropriate receptor to be influenced by the signaling chemical - a process called [blank_start]signal transduction[blank_end].

If too little hormone is produced, the condition is called [blank_start]hypersecretion[blank_end].

Many nonsteroid hormones seem to use cAMP as the [blank_start]first messenger[blank_end].

Some hormones produce their effects by triggering the opening of [blank_start]calcium[blank_end] channels.

The [blank_start]pituary[blank_end] regulate(s) the thyroid by producing thyroid-stimulating hormone (TSH).

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

Which of the following is not a peptide

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:

The target cell concept is an example of the [blank_start]lock-and-key[blank_end] model of chemical reactions.

Blood regulator important in blood clotting: [blank_start]Thromboxane[blank_end]. Immunity regulator: [blank_start]leukotrines[blank_end] Local hormone: [blank_start]tissue hormone[blank_end] Lipid Molecules: [blank_start]eicosanoids[blank_end] Inhibits PGE synthesisi: [blank_start]ibuprofen[blank_end]

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