Exam 1 Practice

Which type of hormone requires a carrier protein in the blood?

Lipid-soluble hormone

Where are the target cells for follicle-stimulating hormone?

Ovaries and testes

Which is not characteristic of the endocrine system?

Recovery time: rapid, immediate return to prestimulation level

Once a structure is fully grown and mature, it will probably

down-regulate its receptors for growth hormone, as it no longer needs to continue to grow at a fast rate.

In response to excessive amounts of hormone, a target cell may reduce its number of receptors for that hormone. This is an example of

down-regulation.

The part of the brain that functions as a "master control center" of the endocrine system is the

hypothalamus.

Damage to the liver might impair enzymatic degradation of some hormones. The levels of such hormones in the blood would therefore be expected to

increase.

The pituitary gland is located _________ to the hypothalamus and is connected by the ________.

inferior, infundibulum

The pancreas is located ________ to the stomach, and it lies between the duodenum and the ________.

posterior, spleen

Most hormones are made of chains of amino acids and are therefore

proteins.

Growth hormone is secreted by __________ cells in the anterior pituitary.

somatotropic

When the effects of one hormone reinforce the activity of another hormone on the same target cell, the interaction is said to be

synergistic.

The release of hormones from the adrenal medulla is stimulated by

the sympathetic division of the autonomic nervous system.

Protein hormones are

water-soluble.
