"E/I" refers to "extrinsic" or "intrinsic". In most cases, the extrinsic anterior muscles are flexors of the hand and wrist. The extrinsic muscles of the forearm act upon the hand and wrist. In most cases, the extrinsic anterior muscles are flexors, while the extrinsic posterior muscles are extensors.

The Brachioradialis, flexor of the forearm, is unusual in that it is located in the posterior compartment, but it is actually in the anterior portion of the forearm.
