|
testosterone, attaches to receptors on specific target cells
|
|
what is the marketed name of the chemical agent responsible for milk letdown?
|
pitocin
|
|
What local hormone promotes what happens just after chromatin undergoes coiling into rodlike structures?
|
(mitosis and rodlike structures are chromosomes) growth factors! because they promote cell division and mitosis
|
|
What chemical signal would promote symptoms of redness, heat, swelling, and pain? What cells would this effect?
|
(inflammatory response)Prostaglandins a local hormone, affect neighboring cells, sometimes promoting pain and inflammation
|
|
What would an action of a chemical agent do to increase its uptake of calcium?
|
target cells.
|
|
What type of mechanism does both the endocrine and nervous system make use of?
|
negative feed back

|
Leutinizing hormone, steroids
|
|
what would be a good example of a hormone that doesn't act between body parts?
|
prostaglandins (local hormone), growth factors
|
|
what chemical messenger acts between body parts and influences cell metabolism leading to a change in the structure of bone?
|
Growth hormone
|
|
What condition may cause body cells that lack receptors that are able to combine with the substance produced by interstitial cells in the testes?
|
Androgen insensitivity
|
|
What type of hormone is the growth hormone? What does it influence?

|
why are steroid hormones able to enter the cell?
|
Because they are lipids (they pass through the lipid soluble membrane)
|
|
How do anabolic steroids promote muscle growth/protein growth?
|
By directly activating DNA
