1. Fetal Pig Endocrine Lab Take out Paper AND Write down:
20 pts LAB
Dissection – throat only
Sketch and label – trachea, heart, lungs, thyroid, thymus
Hormones and actions
Teams of 4 – you choose

3.                                                                                                                                                          
                                                                                                                                                         
Thymus Gland
A- cervical thymus B- thyroid gland C- thoracic thymus

4. Fetal Pig Endocrine Lab
Before dissection, tie the pig down to the tray in the position shown to the right.
Using a piece of string, tie the right foreleg to the left foreleg going behind the tray.
Do the same for the hind legs.

5. Fetal Pig Endocrine Lab
Make an incision with a scalpel in the thoracic region ONLY (as shown in 1. and 3., DO NOT cut the trachea or blood vessels.
Sketch pig head and upper body on a separate piece of paper. Draw and label the:
trachea, heart, lungs, thyroid, thymus
THEN
List ALL the hormones & their actions! Yahoo!

6. X Fetal Pig Endocrine Lab
Under each Endocrine gland,
(1) list all the associated hormones
(2) describe the hormone actions (be specific)

7. X Thymus and Thyroid Glands
Thyroxine – TSH from Ant. Pituitary turns on Thyroid, this hormone increases the body’s metabolism (increased cell respiration and thus more energy).
Calcitonin – high Ca++ in blood causes this hormone to be released from Thyroid, it moves excess Ca++ from blood to bone (storage in bone).
