When a person with conductive hearing loss hear the tuning fork through bone conduction longer than or equally as long as through air conduction it is most likely due to something that inhibits the passage of sound waves from the ear canal, through the middle ear apparatus and into the cochlea.
Air transduction is the process of sound transport through the auditory system (sensory organs and sensory system). The air converts the sound into action potentials of the nerve fibers from the eardrum to the ossicles and labyrinth).
In conduction hearing loss, this transduction is impaired and consequently the hearing is limited.
Answers and Explanation:
1) Mr. F's case fits the description of osteoarthritis. Osteoarthritis is a common disease that occurs when the articular cartilage wears down. This cartilage covers the ends of the bones in order to provide a smooth surface where the bones that are articulating can move fluidly against one another. As a result of these surfaces having less articular cartilage, <u>the patient suffering osteoarthritis will experience pain, stiffness, loss of flexibility, and inflammation, among other symptoms</u>. All of these relate to Mr. F's case. The fact that this disease appeared after he stopped exercising, can also relate to how osteoarthritis can be prevented by staying active physically.
2) Anti-inflammatory drugs and analgesics can help Mr. F with his symptoms, since these drugs will decrease swelling and pain, respectively. Moderate, non-weight-bearing exercise is recommended for Mr. F because exercise has been proven to slow the progression of this non-curable disease, but he shouldn't be bearing weights because that could worsen the state of his knees.
3) If Mr. F follows the doctor's recommendations, he will experience less pain and stiffness, but unfortunately, this <u>disease </u><u>has no cure</u>. Given the location of the articular cartilage's degeneration, it is likely that <u>he will develop a limp and experience some deformity in the curves of his legs</u>.
