1

What is the endocrime system?

Q image thumb

A chemical system that uses hormones to control a target organ or organs

2

What is a hormone?

Q image thumb

Hormone: chemical released by a cell or gland that acts on another part of the body

3

What is a target organ?

Q image thumb

Target organ = organ being acted on by hormone

4

What is the "master" gland? 

Q image thumb

The pituitary gland is the "master" gland but in reality the hypothalamus controls the secretions of all the pituitary gland hormones

5

What is the location of the pituitary gland?

Q image thumb

The pituitary gland located in the sella turcica of the sphenoid bone and attached to the hypothalamus via the neural stalk

6

What are the hormones secreted by the anterior pituitary gland? 

Q image thumb

  1. FSH
  2. LH
  3. ACTH
  4. TSH
  5. GH
  6. PRL

7

What are hormones secreted by the posterior pituitary gland?

Q image thumb

  1. ADH
  2. Oxytocin

8

What is the function of the hypophyseal portal system?

Q image thumb

The hypophyseal portal system enables endocrine communication between the hypothalamus and the anterior pituitary gland.

9

What is the pathway of the hypothalamic hormones in the hypophyseal portal system?

Q image thumb

Hypothalamic hormones (releasing or inhibiting) are secreted into the hypophyseal portal system starting with:

  1. the primary capillaries in the hypothalamus,
  2. leading to portal venules
  3. traveling down the infundibulum
  4. to a group of secondary capillaries in the anterior pituitary.
