What type of movement does the contraction of a Extensor produce?
The contraction of a flexor allows the arm or leg to bend
What kind of muscle not responsible for flexion or extension of the arm?
The supinator muscle is a muscle in the forearm that is not directly responsible for flexion or extension of the arm. Its primary function is to rotate the forearm in a movement called supination, where the palm faces up.
What joint actions occurring in a lateral raise during the concentric and eccentric phase?
To see eccentric contraction, look at the biceps curl with flexion around the elbow. As you lower a weight, you are working against resistance, letting the joint angle increase to lower that object under your control.The opposite is the concentric contraction were the arm is flexed upward to decrease the angle at the elbow.
What joins the lower arm and the upper arm?
The upper arm is the humerus, the lower arm is made up of the radius and ulna. The joint connecting the upper is called the humeroulnar joint.
What muscles help you move your lower arm?
The main muscles responsible for moving the lower arm are the biceps and triceps. The biceps are responsible for bending the arm at the elbow, while the triceps are responsible for straightening the arm at the elbow. Additionally, muscles in the forearm, such as the flexor and extensor muscles, help with fine movements of the lower arm and wrist.
Base your answer on the diagram of the human arm and on your knowledge of biology Movement of the lower arm bones in the direction indicated by the arrow results from the contraction of?
Movement of the lower arm bones in the direction indicated by the arrow results from the contraction of the biceps muscle. The biceps muscle is responsible for flexing the lower arm at the elbow joint, causing the forearm to move towards the upper arm. In this case, the biceps muscle shortens to pull on the forearm bones, creating the movement.
What effect does the contraction Of the bicep have on the arm?
potato
What happens to the bicep when your tricep contracts?
When the biceps contracts the triceps relaxes slowly. It happens when your arm is bent.
Why does the arm need to be at the high level of the heart while measuring the BP?
Because - if the arm is higher or lower than the heart - it will result in a false reading.
What type of movement does the contraction of a Extensor produce?
The contraction of a flexor allows the arm or leg to bend
How can you lower your Jeeps running boards. bought a 2012 jeep wrangler and had the jeep tubular running boards installed but they are too high. is there a way to lower them?
Look into a running board extension kit that will increase the drop of the running boards. Bestop makes one, it is the Extension Arm Kit, # B7513015.
What kind of muscle not responsible for flexion or extension of the arm?

How long of a shower extension arm can I get?
The longest shower extension arm that I found was 15" . Majority of the shower extension arms that I found were 9 -10 inches long with a few at 12 inches. It should be noted that there was at least one 9 inch shower extension arm where two of them could be combined for a total of 18 inches.
Muscles used in arm extension?
Extension of the arm at the shoulder is due to:Latissimus DorsiPosterior fibers of the DeltoidTeres MajorExtension of the elbow joint is almost entirely due to triceps brachi
What type of movement and contraction is in chest compression?
Chest compressions involve rhythmic pressing down on the chest to help circulate blood when the heart is not pumping effectively. The movement is a downward force applied to the chest while the contraction is a compression of the heart between the sternum and the spine.
What happens to your upper arm as you raise the lower arm?
The biceps brachii muscle will contract, pulling the lower arm up.
What joint actions occurring in a lateral raise during the concentric and eccentric phase?
To see eccentric contraction, look at the biceps curl with flexion around the elbow. As you lower a weight, you are working against resistance, letting the joint angle increase to lower that object under your control.The opposite is the concentric contraction were the arm is flexed upward to decrease the angle at the elbow.
