So, tendons connect muscle to bone. When we dissect the fetal pig in lab, we will see superficial and deep fascia, epimysium, and periosteum. Generally, body movements occur when muscles contract across diarthrotic joints. There are 12 primary movements. A combination of flexion, extension, abduction, and adduction that results in the proximal end of a limb remaining stationary while the distal end moves in a circle.
Antagonists are muscles that oppose or reverse the action of a prime mover.
The antagonistic movement of flexion is extension, so the antagonist to the biceps brachii is the triceps brachii. You must know the general origins and insertions for all of the muscles in your Hot List. Find the general location of the muscle. Let's use the biceps brachii as an example. You should know by now that the biceps brachii is located on the anterior aspect of the arm.
