16. Draw the inner or mesal aspect of your dissection of the arteries 

 of the thoracic limb and label all parts. 



17. Draw cross-section of arm at middle of humerus to show location 

 of main artery and vein. 



18. Draw cross-section of the middle region of the forearm to show

 to the bones as seen from the plantar aspect. 



22. At what joints in its course is the chief artery of the pelvic limb 

 most superficial? 



23. Describe the difference in structure of a vein and an artery. 



24. What veins open into each auricle of the heart?
