The muscular and skeletal systems work together to cause movement. When skeletal muscles attached to a bone contract, they pull on that bone. Different muscles can pull bones in opposite directions. For example, a flexor muscle acts to bend a movable joint inward. An extensor muscle pulls bone in the opposite direction to straighten the joint. The coordinated activity of several diverse muscles allows animals to perform complex movements like walking, running, swimming, and flying.
In this laboratory exercise, the students will dissect a chicken wing. The dissection will allow the students to examine bones, muscles, joints, and connective tissue.
