Module 1 Unit 3 - Endocrine Control

Question 1

Answer 1

Oxytocin and ADH (RELEASED FROM POSTERIOR PITUITARY, MADE IN HYPTHALAMUS)

Question 2

Anterior Pituitary hormones

Answer 2

TSH, ACTH, Prolactin, GH, Gonadotropins (FSH and LH) (MADE IN PITUITARY)

Question 3

Where are vesicle mediated hormones made? Where are they stored until release?

Answer 3

Rough ER, Cytoplasm of the cell

Question 4

Where are non-vesicle mediated hormones made? Which hormones are these?

Answer 4

Smooth ER, Steroids

Question 5

Which hormones are carrier bound in the blood stream?

Answer 5

Thyroid hormones and steroids

Question 6

How does carrier protein binding correlate to half life

Answer 6

positive correlation. Higher binding ratio means longer half life

Question 7

Up-regulation

Answer 7

production of more hormone receptors to increase sensitivity in response to low hormone levels

Question 8

Down-regulation

Answer 8

Reduce number of hormone receptors to decrease sensitivity

Question 9

Lipid soluble hormones

Answer 9

enter cell by passing membrane

Question 10

Non-lipid hormone

Answer 10

cannot cross. use second messenger system

Question 11

What is the non steroid hormone that is the exception to the rule and binds to an intracellular receptor?

Answer 11

Thyroid hormone. It has a transporter molecule

Question 12

Answer 12

cells in anterior pituitary that make GH
