receptor 200

Click to reveal the question

Receptor200
  • This is the mechanical stimulus that changes the discharge frequency from auditory receptors.

What is the bending of a hair cell?

Return to

Game Board

receptor 300

Receptor 300
  • Auditory receptors are located in this portion of the membranous labyrinth.

What is the cochlea?

Return to

Game Board

receptor 400

Click to reveal the question

Receptor 400
  • This organ houses the auditory receptor.

What is the organ of Corti?

Return to

Game Board

receptor 500

Click to reveal the question

physiology 100

Click to reveal the question

Physiology 100
  • The auricle is designed to achieve this function in the auditory system.

What is collect pressure waves from the environment?

Return to

Game Board

physiology 200

Click to reveal the question

Physiology 200
  • The external auditory meatus is designed to achieve these functions in the auditory system.

What are focus and amplify pressure waves from the environment onto the tympanic membrane?

Return to

Game Board

physiology 300

Click to reveal the question

Physiology 300
  • Pressure waves in the environment are converted into fluid waves inside the inner ear by these structures.

Where are the ossicles?

Return to

Game Board

physiology 400

Click to reveal the question

Physiology 400
  • Fluid waves inside the cochlea cause movement of this structure which in turn causes the bending of hair cells.

What is the basilar membrane?

Return to

Game Board

physiology 500

Click to reveal the question

Physiology 500

The accuracy of the sound transmitted from the outer ear to the inner ear (fidelity) is regulated by this mechanism.

What is variable stiffness of the ossicles regulated by tension in the tensor tympani and stapedius muscles?

Return to

Game Board

central pathway 100

Click to reveal the question

Central Pathway 100
  • The cell bodies of first-order neurons comprise this ganglion.

What is the spiral ganglion?

Return to

Game Board

central pathway 200

Click to reveal the question

Central Pathway 200
  • Auditory information travels to the brain via this cranial nerve.

What is the vestibulo-cochlear nerve (CN VIII)?

Return to

Game Board

central pathway 300

Click to reveal the question

Central Pathway 300
  • The central pathway of the auditory system is organized as this type of projection system.

What is a bilateral projection system?

Return to

Game Board

central pathway 400

Click to reveal the question

Central Pathway 400
  • Auditory information destined for the cortex projects via this thalamic relay.

What is the medial geniculate nucleus?

Return to

Game Board

central pathway 500

Click to reveal the question

Central Pathway 500

The variable stiffness of the basilar membrane is the origin of this type of organization found throughout the central pathway of the auditory system.

What is tonotopic organization?

Return to

Game Board

miscellaneous i 400

Click to reveal the question

MiscellaneousI 400
  • This flexible membrane helps to prevent the force of propagating fluid waves from damaging the cochlea.
