Answers to the muscle tests - tuesday muscle test

There will be few details that will be related to the lamprey and the protochordates – try and identify some of these before the next lab

An example – the tunicate circulatory system – what is unique about it?

Or when does the liver first appear in the chordates?

How does the shark circulatory system differ from the cat, does the necturus fit in between them?

A few things to remember when you start looking at the internal organs – what are the essential characters of vertebrates?

Metamerism – as you saw in the muscles there isn’t any observable segmentation in the mammal except in the thoracic region; the salamander is still having myomeres

Cephalization – the concentration of nervous control is seen prominently in the shark chondrocranium, but you see that the mammal (importantly the humans) have the largest cranial space/volume (read about the hobbit).

Bilateral symmetry – externally you can see the symmetry. How is it inside? Are all organ systems symmetric? How about the vascular and nervous system?

I will use this page to make any announcements for the lab sections that I teach. Book mark the page;

Follow instructions in class;

At the end of each lab you must all have written down what you did, why you did what ever you did, how, who, everything;

I want you to do this for evey lab.

I may check it and may tie your extra credit to this.

I suggest maintain a lab notebook.

Ask questions, lots of them, I’ll try to answer what I know.

Osmosis refer the paper/article on the link below for style. Mimic the style for your lab reports.
