Question

question 18 (2.5 points)
the cochlear duct in the inner ear helps to maintain body balance or equilibrium.
true
false
question 19 (2.5 points)
receptors on the taste buds send their stimuli through three cranial nerves to the cerebral cortex for interpretation.
true
false

Explanation:

• For Question 18: The cochlear duct is mainly involved in hearing (converting sound vibrations into neural signals). The structures that help maintain body balance or equilibrium are the semicircular canals, utricle, and saccule in the inner ear.
• For Question 19: Taste buds on the tongue send stimuli through three cranial nerves - the facial nerve (VII) for the anterior two - thirds of the tongue, the glossopharyngeal nerve (IX) for the posterior one - third, and the vagus nerve (X) for some areas of the throat and epiglottis. These signals are then sent to the cerebral cortex for interpretation.

Answer:

Question 18: B. False
Question 19: A. True
