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.
The latissimus dorsi is responsible for extension, adduction, transverse extension also known as horizontal abduction, flexion from an extended position, and (medial) internal rotation of the shoulder joint.It also has a synergistic role in extension and lateral flexion of the lumbar spine. 43% had a substantial amount of muscular fibers in the latissimus dorsi originating from the scapula. 2  36% had few or no muscular fibers, but a soft fibrous link between the scapula and the latissimus dorsi. 3  21% had little or no connecting tissue between the two structures.
