13 important questions on Sensory system - Auditory system
Where does the middle ear consist of?
Where does the inner ear consist of?
With what is the membranous labyrinth filled?
high in
-> inside bony labyrinth
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
Where is the endolymph from the membranous labyrinth produced?
What are the parts of the membranous labyrinth?
Of what three compartments does the cochlea consist?
Where does the organ of Corti consists of?
What is characteristic for the outer hair cells?
Stereocilia embedded in tectorial membrane
Contractile
What is characteristic for the inner hair cells?
Stereocilia can freely move
How does the organ of Corti work?
So, each frequency causes max resonation of basilar membrane at specific location along its length. This results in local stimulation of the organ of Corti. This results in local stimulation of the neurons in the spiral ganglion. This eventually results in stimulation of a specific area of primary auditory cortex.
What is characteristic for the basilar membrane?
To which structures is the information from the ear passed to?
- from infC to superior colliculus
- from infC to thalamus nucleus (medial geniculate nucleus)
- From thalamus to primary auditory cortex
What is directional hearing?
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
