Ventral Muscles

Pectoralis Major

This muscle is located in between the sternum and the front leg. It is used to move the foreleg towards the chest. To isolate this muscle you must first break off the connective tissue above the muscle with your blunt probe. Also remove the connective tissue from underneath the muscle so you can use your blunt probe to lift up the pectoralis major. 

Latissimus Dorsi

This muscle is below the pectorialis major. This muscle moves the foreleg dorsally and caudally. You must use your blunt probe to remove the connective tissue from the top of this muscle in order to isolate it. The fibers of this muscle run anterior direction, opposite those of the pectoralis major. You have to lift up the arm of the pig to isolate it.
