Why do your hand muscles contract when you yawn?
When you yawn, the muscle responsible for opening your mouth (digastric muscle) can also activate some of the muscles in your hand as they are all controlled by the same cranial nerve, the trigeminal nerve. This phenomenon is known as referred motor activity.
What is the meaning of flexor?
A muscle which bends or flexes any part; as, the flexors of the arm or the hand; -- opposed to extensor.

An exception to this generalization is the extensor flexor musculature of where?
An exception to this generalization is the extensor-flexor musculature of the forearm. In this region, the extensor muscles primarily control extension of the wrist and fingers, while the flexor muscles primarily control flexion. This muscle group plays a crucial role in intricate hand movements and grip strength.
What type of muscle is associated with the hand?
hold on, let me look for it........... its skeletal muscle because i went onhttp://graphics8.nytimes.com/images/2007/08/01/health/adam/19917.jpg and it shows the smooth muscle, skeletal muscle, and cardiac muscle...and the skeletal mucle is closer to your hand than any other muscles. if u dont believe me go on that website (actually its not a website, its on google images).
How do the flexor and extensor muscles work together in the body?
When bones attached to a muscle are connected by a flexible joint, contraction of the muscle moves the skeleton. The muscle is called a flexor if the centers of the connected bones are brought closer together when the muscle contracts, and the movement is called flexion. (Biceps)The muscle is called an extensor if the bones move away from each other when the muscle contracts, and the movement is called extension. (Triceps)
