Self-Assessment

Which muscle contracts to produce the acoustic reflex measured clinically?

Which nerve provides the motor (efferent) supply to the stapedius muscle?

What happens to middle-ear admittance when the stapedius contracts?

The acoustic reflex is named according to which ear?

When one ear is stimulated, the acoustic reflex normally occurs in:

Reflex decay is conventionally tested only at 500 and 1000 Hz because:

A positive (abnormal) reflex decay result is defined as the amplitude falling to:

Reflexes are absent with the probe in the right ear (both conditions) but normal with the probe in the left ear. This pattern most suggests:

Both contralateral cells are absent while both ipsilateral cells are normal. This diagonal pattern suggests:

In ANSD, the acoustic reflex is characteristically absent alongside:

The Metz test identifies recruitment when the reflex threshold is:

Broadband noise stimuli typically elicit the reflex at levels that are:

The crossed (contralateral) reflex pathway additionally requires intact:

A facial nerve lesion will spare the acoustic reflex when the lesion is located:

Roughly what degree of cochlear hearing loss is typically needed before reflex thresholds begin to elevate consistently?

An eighth-nerve tumour most characteristically affects reflexes elicited by:

Reflex decay testing is conventionally performed at a stimulus level of:

Absent reflexes with present OAEs in an ear that hears near-normally should first prompt consideration of:

Which tympanogram type would best help distinguish ossicular discontinuity from otosclerosis?

The clinical value of recording BOTH ipsilateral and contralateral reflexes is best illustrated by:

A change in admittance of at least what magnitude is conventionally taken as a reflex?

The afferent limb of the acoustic reflex arc is carried by the:

The protective effect of the acoustic reflex is limited mainly because:

A unilateral conductive loss of about 30 dB will most likely make the reflex on the affected probe side:
