Quiz 10 + 11 guide + Endocrine: lab preview

Quiz 10 + 11 guide
For quiz 10 there will be identification questions from sheep brain, brain model, cow eye, eye model, ear model, slides.
For theory please follow the CNS, eye, ear etc etc lab preview notes which seems to be extensive. Click on this link: CNS,eye,ear,stretch reflex: lab preview Feel free to e-mail me if you have any doubts of CNS etc etc lab.
Also we shall be having another quiz (Quiz 11) from last lab of Endocrine . This will be open book.

Endocrine: lab preview
Main focus of this lab is anatomy, histology and regulatory functions of different endocrine organs.
Though the quiz will be open book, I personally think there is lot of information in this lab that you need to remember. Especially the histological section (you have lots of slides).

Couple of experiments that we will be doing:
1) Study of Antidiuretic hormone (ADH): Use frogs for this purpose. Since ADH assists in water reabsorption, the frog that has been injected with ADH will weigh more if kept in water. This can be known by weighing frog at 0 hr and then on at 30 minutes interval for two hours.

2) Role of Thyroid hormones: We will be demonstrating this in mice that are either normal, hypothyroid, or hyperthyroid and measuring their rate of oxygen consumption in Scholander respirometer. Decide which group wants what kind of mice. Group with hyperthyroid mice needs to take extra care of mice.

3) Oxytocin induced milk release: We will not be able to do this experiment as females failed to get pregnant however you need to know the theory behind this experiment.

HURRAY END OF LABS.
