The sense organs associated with equilibrium are within the
a. outer ear.
b. middle ear.
C. inner ear.
d. tympanic membrane.
Introduction :
With the help of two sets of sensory organs, equilibrium is maintained in the body. One set of sense organs makes the head and body stable and makes a sense of gravitational equilibrium. The second set of organs balances the head and body and makes the sense of rotational equilibrium.
Answer to Problem 1PL
Correct answer :
Option (c), inner ear.
Explanation of Solution
Explanation/justification for the correct answer :
Option (c) is inner ear. The inner ear contains the sense organs that senses hearing and maintains equilibrium. Hence, this option is correct.
Explanation for incorrect answer :
Option (a) is outer ear. The function of the outer ear is to collect the sound waves and direct them to the tympanic membrane. Hence, this option is incorrect.
Option (b) is middle ear. Its function is to transfer acoustic energy from compression waves to fluid membrane waves present in the cochlea. Hence, this option is incorrect.
Option (d) is tympanic membrane. Tympanic membrane is the eardrum that receives sound vibrations and then transmit them to the auditory ossicle. It is the part of the outer ear. Hence, this option is incorrect.
Option (c), inner ear.
