1

Which of the following is not a role of the endocrine system?

1

The classification of hormones are protein-derived and lipid-derived.

1

Protein-derived hormones are ( water insoluble, water soluble ) and have a(n) ( cell surface receptor, intracellular receptor ).

1

Lipid-derived hormones are ( water soluble, water insoluble ) and have a(n) ( intracellular receptor, cell surface receptor ).

1

Protein-derived hormones are

1

Lipid-derived hormones are

1

The components of the endocrine system are

1

Endocrine glands have ( no ducts and are vascular, ducts and are vascular ). The cell product is secreted into ( blood stream, ECF, blood stream and ECF ) and is taken up to be distributed throughout the body.

1

Exocrine glands secrete nonhormonal products into ducts that exit onto epithelial surfaces.

1

Which glands do not go into the bloodstream or body and its released chemicals affect only adjacent cells?

1

The secretion or release of hormones is controlled by

1

Steroid/thyroid hormones use a special transport protein and circulate faster.

1

The concentration of hormones in circulation depends on the and .

1

Hormones are inactivated by

1

Identify the listed components of the Second Messenger/G Mediated/Protein Mechanism

1

The Gene Activation (the second of the two molecular mechanisms of hormone action) is the mechanism for lipid soluble hormones.

1

Up regulation refers to the loss of receptors.

1

Up regulation refers to: cell synthesizing increases receptors as hormone levels decrease.

1

Hormones alter target cell activity by altering a protein (enzyme).

1

Stimulus of the endocrine system can be a specific chemical, regulatory hormone or neural.

1

The functions of the hypothalamus are secretion of hormones that control the activities of the ( hypothalamus, thalamus, anterior pituitary gland ), synthesis and release of ( ADH and oxytocin, epinephrine and norepinephrine ) in the posterior pituitary gland and controls the adrenal medulla which releases ( epinephrine and norepinephrine, ADH and oxytocin, thyroid hormone ).

1

The pituitary gland is an extension of the

1

The adrenal gland is found on the

1

The adrenal medulla is endocrine tissue involved in fight or flight response.

1

The adrenal cortex is endocrine tissue and produces 12+ steroid hormones.

1

The following are related to androgen hormones (sex hormones)

1

Thyroid hormone gland targets most cells and its functions are

1

In calcium homeostasis, calcitonin works to ( increase, lower ) calcium levels in the blood whereas parathyroid hormone works to ( increase, lower ) calcium levels. These two hormones are therefore ( synergistic, antagonistic ).

1

Calcitonin in the thyroid gland ( lowers, raises ) calcium levels in blood. It's target cells are ( the liver and spleen, bones and kidneys ), and it inhibits osteoclasts and stimulates excretion in kidneys. One example of a disease related to calcitonin is ( myxedeia, Addison's ).

1

Parathyroid hormone in the parathyroid gland ( decreases, increases ) calcium levels in blood. It's target cells are ( bones and kidneys, the stomach and liver ). It stimulates ( osteoclasts, osteoblasts ), inhibits ( osteoclasts, osteoblasts ) and ( reduces, increases ) excretion. It stimulates the ( bones, kidneys ) to make calcitriol.

1

The parathyroid hormone increases calcium production.

1

The pancreas gland is

1

Insulin, produced by the pancreas gland, increases glucose levels.

1

Glucagon raises glucose levels.

1

Insulin and glucagon are antagonistic in glucose homeostasis.

1

Type two diabetes involves

1

Select the answer that does not relate to the effects of hormones

1

Growth requires

1

The alarm phase consists of an ( immediate short term response to crisis, immediate long term response to crisis ). It is associated with the fight or flight reaction where ( norepinephrine, epinephrine ) dominates. It includes a sympathetic response, and a reduction of water loss occurs.

1

The resistance phase includes ( short term, long term ) metabolic adjustments. It occurs if stress lasts longer than a few ( seconds, hours, minutes ). ( Glucocorticoid, Norepinephrine ) hormones dominate aided by epinephrine, GH, thyroid, alderostone and ADH hormones. Energy demands stay ( low, high ).

1

The exhaustion phase is a collapse of vital systems where organ system failure occurs due to electrolyte imbalance.

The classification of hormones are protein-derived and lipid-derived.

Protein-derived hormones are water insoluble water soluble( water insoluble, water soluble ) and have a(n) cell surface receptor intracellular receptor( cell surface receptor, intracellular receptor ).

Lipid-derived hormones are water soluble water insoluble( water soluble, water insoluble ) and have a(n) intracellular receptor cell surface receptor( intracellular receptor, cell surface receptor ).

Protein-derived hormones are
