The idiom let sleeping dogs lie means not to stir up old conflicts or provoke an argument over unresolved issues. It is often better to agree to disagree and move forward rather than trigger hostilities over an ongoing difference of opinion.
There are many muscles in the forearm. In the anterior compartment, they are split into three categories; superficial, intermediate and deep. In general, muscles in the anterior compartment of the forearm perform flexion at the wrist and fingers, and pronation.he superficial muscles in the anterior compartment are the flexor carpi ulnaris, palmaris longus, flexor carpi radialis and pronator teres. They all originate from a common tendon, which arises from the medial epicondyle of the humerus.
There are more than a dozen muscles that maneuver the hip through extension and flexion. But rather than all the hip muscles firing at once to both extend and flex the hip, the muscles that contract in flexion, during which the extensors relax, are relaxed during extension while the extensors contract.Flexion occurs when the angle between articulating bones decreases, like when you flex your biceps.ut rather than all the hip muscles firing at once to both extend and flex the hip, the muscles that contract in flexion, during which the extensors relax, are relaxed during extension while the extensors contract.
