<unk>  is a<unk>  test that examines the function of the C5<unk>  arc and the C6<unk>  arc. The test is performed by using a tendon hammer to quickly depress the<unk>  brachii tendon as it passes through the cubital fossa. Specifically, the test activates the stretch receptors inside the<unk>  brachii muscle which communicates mainly with the C5 spinal nerve and partially with the C6 spinal nerve to induce a<unk>  contraction of the<unk>  muscle and jerk of the forearm. A strong contraction indicates a "brisk"<unk> , and a weak or absent<unk>  is known as "diminished". Brisk or absent<unk> es are used as clues to the location of neurological disease. Typically, brisk<unk> es are found in lesions of upper motor neurons, and absent or reduced<unk> es are found in lower motor neuron lesions. A change in the<unk>  indicates pathology at the level of musculocutaneous nerve, segment C5/6 or at some point above it in the spinal cord or brain.
