Mink Dissection of Muscles
In this portion of our study of the Mink, we will be focusing on the muscular system. These instructions tell you what muscles you are to identify and provide instructions on information you are expected to learn about those muscles. Additionally, these instructions will reference passages in the dissection manual that explain how to locate the muscles listed here.
The word “dissect’ means to separate; the blunt probe will be your most useful tool with occasional use of scissors. When dissecting, or separating muscles, you are tearing the deep fascia that lies between muscles. As your feel for separating muscles improves, you will develop a sense of when you are applying too much pressure and are likely tearing into a muscle. If you see individual, torn, muscle fibers (fascicles), that is an indication you have broken through the perimysium that surrounds each muscle; this is obviously undesirable.
You will quickly learn there is a good deal of variation in the dissection specimens. The muscles appear different colors, individual animals have varying amounts of superficial fascia (adipose/fat), the muscles differ in size and exact placement.
