Chapter 15, Problem 19RAC
Summary Introduction
Introduction:
The organs of hearing and balance can be categorized into three parts:
- External ear: The external ear helps in collecting the sound waves and directing it to the interior.
- Middle ear: The middle ear has the air-filled cavity. The middle ear also possesses three auditory ossicles known as stapes, incus and malleus.
- Inner ear: The inner ear has the sensory organs for hearing and balance.

Given these ear bones:(1) incus (2) malleus (3) stapesChoose the arrangement that lists the ear bones in order from thetympanic membrane to the inner ear.a. 1,2,3 b. 1,3,2 c. 2,1,3 d. 2,3,1 e. 3,2,1
which statements are true about the Auditory Structures and their Functions
a. The middle ear is connected to the mastoid air cells.
b. The inner ear has three parts: the semicircular canals; the vestibule, which contains the utricle and the saccule; and the cochlea.
c. The cochlea is a circular-shaped canal within the temporal bone.
d. The cochlea is divided into two compartments by the vestibular and basilar membranes. The scala vestibuli and scala tympani contain perilymph. The cochlear duct contains endolymph and the spiral organ (organ of Corti).
which statements are true about the Auditory Structures and Functions
a. The external ear consists of the auricle and external acoustic meatus.
b. The middle ear connects the external and inner ears. The tympanic membrane is stretched across the external acoustic meatus.
c. The malleus, incus, and stapes connect the tympanic membrane to the oval window of the outer ear.
d. The auditory tube connects the middle ear to the pharynx and functions to equalize pressure.
