Question

The  ____________  ear consists of the  ____________  that funnels sound waves, the external acoustic meatus, and the  ____________  that vibrates like a drum when sound waves hit.

The  ____________  ear consists of the air-filled chamber, called the  ____________ , and ossicles called the  ____________  that transmit sound vibrations to the oval window.

The  ____________ , also called the pharyngotympanic tube, connects the middle ear to the pharynx to equalize the  ____________  in the outer and middle ear.

The organ of equilibrium is the  ____________ , and the organ of hearing is called the  ____________ , which is a coiled snail-like tube; this structure converts sound waves to nerve impulses.

The inner ear also consists of tubes called the  ____________  labyrinth that lines the bony labyrinth and is filled with  ____________ , a similar fluid to intracellular fluid; the fluids are important in transmitting sound waves.

Explanation / Answer

Anser:

The corrtect statements with blanks filled is as follows;

The outer ear consists of the auricle (pinna) that funnels sound waves, the external acoustic meatus, and the eardrum (tympanic membrane) that vibrates like a drum when sound waves hit.

The middle ear consists of the air-filled chamber, called the tympanic cavity, and ossicles called the malleus, incus, and stapes that transmit sound vibrations to the oval window.

The Eustachian tube, also called the pharyngotympanic tube, connects the middle ear to the pharynx to equalize the pressure in the outer and middle ear.

The organ of equilibrium is the vestibule, and the organ of hearing is called the cochlea, which is a coiled snail-like tube; this structure converts sound waves to nerve impulses.

The inner ear also consists of tubes called the osseous labyrinth that lines the bony labyrinth and is filled with perilymph, a similar fluid to intracellular fluid; the fluids are important in transmitting sound waves.
