Projections for contract services in the example are more realistic when the run rate is used ($276,000) because many new contracts signed in Year 1 were signed late in the year. Using annual data for contract services results in a very conservative estimate ($122,100) for Year 2.
Flexors: Superficial Layer. The superficial layer of flexors in your forearm contains three muscles -- flexor carpi radialis, or FCR; flexor carpi ulnaris, or FCU; and flexor digitorum superficialis, or FDS. The FCR attaches to the base of your wrist, toward the thumb-side of your hand.
Flexion of the forearm is achieved by a group of three muscles â the brachialis, biceps brachii, and brachioradialis. These flexor muscles are all located on the anterior side of the upper arm and extend from the humerus and scapula to the ulna and radius of the forearm.Additionally, the biceps brachii operates as a supinator of the forearm by rotating the radius and moving the palm of the hand anteriorly.uscles of the Arm and Hand. The muscles of the arm and hand are specifically designed to meet the bodyâs diverse needs of strength, speed, and precision while completing many complex daily tasks.
