Answer 2

endocrine glands

Question 3

endocrine communication

Answer 3

hormone release

Question 4

neurons that release hormones into the blood

can modify the reactivity of cells to specific transmitters

act slower than neurotransmitters but have long lasting effects

Answer 6

neuromodulators

- testosterone and estrogens

Answer 10

neurosteroids

Question 11

alters protein production and gene expression

Answer 11

steroid receptor complex

Question 12

system output feeds back and inhibits further secretion

Answer 12

negative feedback

Question 13

Posterior pituitary stores and secretes 2 hormones

Answer 13

oxytocin and vasopressin

Question 14

does the posterior produce two hormones?

Answer 14

NO - the hypothalamus produces them , the pituitary just stores them
