Chapter 39- Animal Hormones (Achieve) Endocrine System

Which stateent about antidiuretic hormone (ADH) is true?

In response to low blood pressure, the posterior pituitary secretes more ADH

It is least likely that what is involved in molting in arthropods?

Prolactin

Which statement about growth hormone is true?

They stimulate cells to take up amino acids

If anterior pituitary cells are grown in a dish, they secrete melanocyte stimulating hormone (MSH). Adding extracts of the hypothalamus to the dish decreases the release of MSH. These results indicate that the hypothalamus can control MSH-producing cells by 

Secreting MSH release inhibiting hormone

Circulating thyroxine exerts negative feedback on

Cells of the anterior pituitary, making them less responsive to thyrotropin-releasing hormone (TRH)

What statement relating to endocrine signaling is true?

Some endocrine cells exist as single cells within a tissue

What is the main conclusion drawn from pioneering experiments with the bloodsucking bug Rhodnius?

A blood meal stimulates production of a substance in the head, which slowly diffuses throughout the body and triggers molting

What do target cells for a hormone do?

Express a receptor protein for the hormone 

What does the specific response to a hormone depend on?

Target cell

Which statement about ecdysone is true?

It induces expression of genes encoding enzymes needed for digestion of old cuticle and formation of new cuticle

What do axons of hypothalamic neurons do?

Transport vesicles containing the hormones that end up leaving in the bloodstream at point 2

Sequence of components leading up to cortisol release

Stressful stimulus, hypothalamus, corticotropin-releasing hormone, anterior pituitary, adrenocorticotropin, adrenal cortex, cortisol

Only the cells that synthesize receptor molecules respond to

Hormones

There are separate what for growth hormone and thyroid stimulating hormone?

Releasing hormones

Compared
