tympanic cavity

The mastoid process will appear as the tympanic cavity continues to grow.

On the other side of the tympanum is a small air-filled space called the tympanic cavity.

In lemurs, the tympanic cavity, which surrounds the middle ear, is expanded.

The tympanic cavity is a small cavity surrounding the bones of the middle ear.

The roof of the tympanic cavity, the tegmen tympani, is small.

The middle ear consists of the tympanic cavity and the epytimpanic recess.

This last structure will establish the final connection between the tympanic cavity and the nasopharynx.

The branches of the tympanic cavity provide innervation to the mucosa of the middle ear.

He realized the importance of the Eustachian tube and its role in adjusting air pressure in the tympanic cavity.

Through it the chorda tympani nerve enters the tympanic cavity.

The whole structure from the tympanum to this small opening, including the tympanic cavity and the ossicles, is called the middle ear.

The hollow space of the middle ear has also been called the tympanic cavity, or cavum tympani.

The middle ear, which includes the tympanic cavity and the auditory tube, originates from the first pharyngeal pouch.

It opens in front into that portion of the tympanic cavity which is known as the attic or epitympanic recess.

The tympanic cavity in lorisoids also has two accessory air spaces, which are not present in lemurs.

Hemotympanum, or hematotympanum, refers to the presence of blood in the tympanic cavity of the middle ear.

The sinus receives some cerebellar and inferior cerebral veins, and veins from the tympanic cavity.

The squamosal bone lacks a suspensory process contacting the tegmen tympani, the roof the tympanic cavity.

Around day 30 of gestation, the endoderm-lined first expands to form the tympanic cavity, which subsequently envelops the inner ear ossicles.

"They have no outer ear-in itself not too important, but they have no ossicle and no tympanic cavity.

Within the tympanic cavity the tympanic nerve forms a plexus on the surface of the promontory of the middle ear to provide general sensation.

In lorisoids, however, the tympanic cavity is smaller and the ectotympanic ring becomes attached to the edge of the auditory bulla.

He showed the connection between the mastoid cells and the tympanic cavity, and made observations on physiologic and pathologic processes of the ear.

As it is, however, air flows in and out through the Eustachian tube, keeping the pressure within the tympanic cavity continually equal to that in the auditory canal.

These canals run from the tympanic cavity forward and downward to the retiring angle between the squama and the petrous portion of the temporal bone.
