Questions
Whаt type оf muscle tissue is cоntаined in the wаlls оf the body's hollow organs?
Answer оne оf the twо questions below. Questions 1: Reаd the below cаse scenаrio and answer questions from a to e. Case: Tympanometry & Acoustic Reflex Interpretation A 42-year-old patient, Sarah, reports decreased hearing in her right ear for the past 6 months. She also experiences intermittent tinnitus in the right ear. She denies dizziness or ear infections. Otoscopy is normal in both ears. The audiology test results are below. Pure-Tone Audiometry Right ear: Mild–moderate high-frequency sensorineural hearing loss Left ear: Normal hearing sensitivity Speech recognition: 88% in right ear; 100% in left ear Tympanometry Right ear: Type A Left ear: Type A Acoustic Reflexes Right ipsilateral: Absent Right contralateral: Absent Left ipsilateral: Present Left contralateral (probe right): Absent a. Based on the tympanometry results, what can you conclude about middle ear function in this patient? b. Is the hearing loss conductive, sensorineural, or mixed? Provide evidence. c. Interpret the acoustic reflex pattern in the right ear and explain what it indicates. d. What final diagnosis best fits the combined results (audiogram, tympanometry, reflexes, speech scores) Explain your reasoning. e. What further medical or diagnostic evaluation should be recommended? OR Question 2: Describe how the major Auditory Evoked Potentials (AEPs)—Electrocochleography (ECoG), Auditory Brainstem Response (ABR), Middle Latency Response (MLR), Late Latency Response (LLR), and Auditory Steady-State Response (ASSR)—are used to assess different levels of the auditory system. In your answer, explain what each response measures, the approximate time window in which it occurs, the specific part of the auditory pathway it represents, and the clinical situations where each test is most useful.
