The triceps reflex is tested as part of the neurological examination to asses the sensory and motor pathways within the C7 and C8 spinal nerves. The triceps reflex originates from the triceps brachii muscle, and is initiated by the C7 nerve root.
The test is performed by tapping the tendon while the forearm is hanging loose at a right angle to the arm. A sudden contraction of the triceps muscle causes extension of the forearm, and indicates a normal reflex.
