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. Paronychia is an infection of the surrounding tissue, where the nail meets the skin; a paronychia infection causes inflammation, and may also lead to the formation of pus-filled abscesses.
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.
A flexor reflex, which is also called a withdrawal reflex, is a multisynaptic reflex. It is a type of protective reflex where a painful stimulus triggers the contraction of flexor muscles. These reflexes have a slower onset and a longer response than the stretch (extensor) reflexes. A flexor reflex requires the contraction of a flexor muscle and relaxation of the extensor muscle in that limb. A good example of a flexor reflex is when you touch your forearm to the side of a hot oven.
