Intraspecies Transplantation and Ear Anatomy

These flashcards cover key concepts related to intraspecies transplantation and the anatomy of the ear, including important structures and their functions.

Intraspecies transplantation

The process of transplanting organs or tissues between animals of the same species.

Auricle

Also known as the pinna; the outer part of the ear that helps to filter and focus sound.

External auditory meatus

The technical term for the ear canal or ear hole.

Tympanic membrane

Also known as the eardrum; it separates the external ear from the middle ear.

Ossicles

The three tiny bones in the middle ear: malleus, incus, and stapes.

Eustachian tube

A tube that connects the middle ear to the back of the nose, helping to equalize air pressure.

Cochlea

The spiral-shaped organ in the inner ear responsible for hearing.

Action potential

A change in electrical potential associated with the passage of an impulse along the membrane of a muscle cell or nerve cell.

Vestibule

The central part of the inner ear that contains structures involved in balance.

Otoliths

Tiny stones in the inner ear that help with balance and sensing gravity.

Scala tympani

The lower chamber of the cochlea, also known as the tympanic canal.

Round window

A membrane-covered opening that allows fluid displacement in the cochlea.

Basilar membrane

A structure in the cochlea that vibrates in response to sound waves, housing the organ of Corti.

Hair cells

Sensory cells in the cochlea that convert sound vibrations into electrical signals.

Cupula

A gelatinous structure within the ampulla of the semicircular canals that aids in balance.
