Insufficient ADH release causes:

*diabetes insipidus

Too much GH in a fully grown adult results in:

Acromegaly

Which lobe of the pituitary is larger and secretes more hormones?

Anterior pituitary

Which of the following hormones is synthesized by the hypothalamus?

Antidiuretic hormone (ADH)

All of the following pituitary hormones are tropic except:

GH

Which is NOT correct regarding growth hormone (GH)?

GH stimulates the kidney to secrete somatomedin.

Which of the following will inhibit the secretion of growth hormone?

Growth hormone-inhibiting hormone (GHIH)

Which hormone induces its target cells to take up glucose, thereby lowering blood glucose levels?

Insulin

Which hormone is secreted by the beta cells of the pancreas?

Insulin

Acromegaly is most frequently diagnosed in:

Middle-aged adults

The metabolic condition called ___________ results from the destruction of the beta cells in the pancreas due to an autoimmune response.

Type 1 diabetes

Which of the following does not have an endocrine function?

Urinary bladder

In which order would blood flow through these structures as it travels from the hypothalamus to the pituitary gland? a: Primary plexus b: Secondary plexus c: Hypophyseal portal veins

a - c - b

The release of hormones from the adrenal cortex is stimulated by

adrenocorticotropic hormone.

ADH secretion will increase when:

blood osmolarity increases

Aldosterone release can be triggered by the presence of the blood-borne messenger angiotensin II or by low levels of sodium, and so its secretion regulation is said to be

both hormonal and humoral.

The antagonistic hormones that regulate the blood calcium level are

calcitonin-parathormone.

The hypothalamic hormone that triggers the release of adrenocorticotropic hormone (ACTH) is

corticotropin-releasing hormone (CRH).

Mineralocorticoid is to aldosterone as glucocorticoid is to ________.

cortisol

"Which hormone stimulates its target cells to divide, increases their rate of protein synthesis, decreases their use of glucose and increases their use of fats? "

growth hormone

Releasing hormones:

increase anterior pituitary secretion

ADH is secreted in response to:

increased osmotic pressure of the body fluids

Calcitonin can lower blood calcium by:

inhibiting resorption by osteoclasts

Cortisol binds to _________ receptors and has the effect of ________ blood glucose levels.

intracellular, raising

Compared to young adults, the elderly usually have ______ levels of circulating growth hormone and _____ levels of circulating sex hormones.

lower, lower

Normally, TH has a ____________ feedback effect on the anterior pituitary, which responds by _____________ release of TSH.

negative; decreasing

The ___________ has both endocrine and exocrine functions.

pancreas

Oxytocin:

release is an example of positive feedback mechanims

The anterior pituitary is also called

the adenohypophysis.

Which organ is responsible for synthesizing ANP?

the heart
