The leverage of the biceps brachii applies its force six times closer to the fulcrum (elbow joint) than the resistance. this means it will need to exert <u>36</u> kg of force to support a load of 6 kg.
The triceps brachii (TB) is the only muscle that lies along the posterior humerus. It is a 3-headed, fusiform muscle that, on the shoulder, works in a third-elegance lever since the force is implemented among the joint axis and the weight.
Within the elbow joint, the triceps brachii muscle attaches to the olecranon method of the ulna posterior to the elbow joint. While the triceps contract, it pulls the olecranon procedure proximally, swinging the ulna distally and lengthening the forearm.
