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.
Sequence. In a simple reflex action: stimulus â receptor â sensory neurone â relay neurone â motor neurone â effector. An effector is any part of the body that produces the response.Here are some examples of effectors: 1  a muscle contracting.2  a gland releasing (secreting) a hormone or other chemical.eflex actions. When a receptor is stimulated, it sends a signal to the central nervous system, where the brain co-ordinates the response. But sometimes a very quick response is needed, one that does not need the involvement of the brain. This is a reflex action.
