How much force would a biceps muscle inserted 4 cm from the fulcrum need to hold the arm stationary at a 90 percent angle?
Only a very small force if the arm only has to be supported.
What other weights do the arm carry and at what angle does the biceps attach to the fore-arm?
What is the distance to the hand from the fulcrum and what is the arm weight (assuming a weight is in the hand and arm weight has to be added to the weight-in-hand)?
The length of the hand to fulcrum is also required.
There is no such thing as 90% angle: 90 degrees perhaps?

What are lines that are not parallel and will never intersect called?
Biceps are the top part of your upperarm, your Triceps are the bottom part of your upperarm
What is the function of the musculocutaneous?
The function of the musculotaneous nerve is to supply motor fibers to the biceps brachii and brachialis muscles as well as providing cutaneous sensation of the lateral forearm.
Explain the function of flexors and in extensors?
these muscle groups either extend a joint, extensors) or contract the joint (flexors). triceps extend the elbow joint, biceps bend the elbow joint.
How many muscles work together move one bone 1 2 3 or 4?
Typically, two or more muscles work together to move a single bone. Muscles operate in pairs: one muscle contracts while the other relaxes to facilitate movement. For example, when bending the elbow, the biceps contract while the triceps relax. This coordinated action allows for smooth and controlled movement.
What is a fulcrum for a biceps curl?
The fulcrum in this case would be your elbow joints. more specifically the trochlea and capitulum on the humerus which articulate with the radius and ulna
What are the load effort force and the fulcrum in a biceps muscle?
In the biceps muscle, the load is the weight or resistance being lifted, such as a dumbbell. The effort force is generated by the muscle itself to lift the load. The fulcrum is the point in the body where the muscle attaches and pivots to create movement.
Where can biceps be found and what does it do?
The biceps are the muscles on your arm which bend your elbow. Ask someone to flex their arm, and they will 99 percent of the time show you their Bicep.
Is your arm a first class lever?
The biceps is an example of a class 3 lever. The triceps is an example of a class 1 lever.
What type of lever do biceps make when they contract to lift a load in the hand?
The biceps muscle functions as a third-class lever when it contracts to lift a load in the hand. In this type of lever, the effort force (biceps) is applied between the fulcrum (elbow joint) and the load (hand weight). Third-class levers are optimized for speed and range of motion rather than force.
Why is the elbow considered a third class lever?
The elbow is considered a third class lever because the effort force is applied between the load (resistance) and the fulcrum. In this case, the biceps muscle (effort force) exerts force between the hand (load) and the joint of the elbow (fulcrum) to produce movement.
What is estimated payout for 10 percent impairment rating distal biceps tendon rupture?
100,000
How can I effectively perform standing ez bar biceps curls to target and strengthen my biceps?
To effectively perform standing EZ bar biceps curls, start by standing with your feet shoulder-width apart and holding the EZ bar with an underhand grip. Keep your elbows close to your body and curl the bar towards your shoulders while keeping your upper arms stationary. Lower the bar back down slowly and repeat for the desired number of repetitions. This exercise targets and strengthens the biceps muscles.
What type of levers are biceps?
Biceps act as a third-class lever in the human body. In this system, the effort is applied between the fulcrum (the elbow joint) and the load (the weight in the hand). This configuration allows for a greater range of motion and speed of movement, although it requires more effort to lift heavier weights compared to first or second-class levers.
What is biceps debridement?
Biceps debridement is removal of devitalized tissue from the biceps.
What are facts about the biceps and triceps.?
biceps are on your upper arm and triceps are below your biceps
What is the difference between brachialis and brachioradialis?
The brachialis muscle is located deep to the biceps brachii and is the main flexor of the elbow joint. The brachioradialis muscle is a superficial muscle located on the lateral side of the forearm that aids in both elbow flexion and forearm supination.
