6.1 Anatomy of the Endocrine System Part 2 Flashcards
How do steroid hormones enter the cell?
freely because they do not need to interact with receptors
Where do steroid hormones perform their “action”?
in the nucleus
What does a steroid hormones do once it enters the nucleus of the target cell?
bind to receptors creating a hormone-receptor complex that activates specific genes leading to protein synthesis
Why do steroid hormones has a more sustained effect on the metabolism of the cell?
create new proteins for the cell
What secretes hormones?
endocrine glands
What are the two types of glands in the human body?
endocrine
exocrine
What are endocrine glands?
ductless glans that secrete their contents directly into the bloodstream
What are exocrine glands?
glands with ducts that secrete their contents into an epithelial surface
What is an example of an exocrine glands?
salivary glands
What is the function of primary endocrine organs?
secrete hormones that will chemically regulate body fuctions
What are the primary endocrine organs?
hypothalamus
pituitary gland
pineal gland
thyroid gland
parathyroid gland
adrenal gland
pancreas
Which primary endocrine organs are located in the brain?
hypothalamus
pineal gland
pituitary gland
Where are the adrenal glands located?
superiorly to each kidney
Where is the thyroid gland located?
neck; attached to the trachea just below the larynx
