Onychia and Paronychia of the Toe â What You Can Do. The terms onychia and paronychia refer to a type of bacterial or fungal infection that strikes the fingernails and toenails. Onychia is an infection of the nail itself, which causes inflammation of the nail and swelling of the surrounding tissue.

Deep Tendon Reflexes. Using a reflex hammer, deep tendon reflexes are elicited in all 4 extremities. Note the extent or power of the reflex, both visually and by palpation of the tendon or muscle in question.
reflex action. an involuntary response to a stimulus conveyed to the nervous system and reflected to the periphery (see also reflex). reflex bradycardia. bradycardia occurring as a reflex initiated by severe atrial or ventricular stretch. positive reaction is a sharp contraction of the muscle of which the tendon is part. The patellar reflex is the best known of these reflexes. Absence indicates a defect in the reflex arc, an exaggerated response suggests an upper motor neuron lesion. Called also myotactic reflex.
