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.
Kinesiologists use planes of motion to describe the movement of joints. Forward and backward movements, called flexion and extension, take place in the sagittal plane. Flexing and extending your elbows, for instance, is a sagittal-plane movement.he action of a pullup takes place primarily in two planes of motion -- the sagittal and frontal. Varying the grip changes the plane of motion. Gripping the bar with your palms facing forward creates more frontal plane movement in the arms.
