Otolith organs (sacs) - utricle & saccule - Macula
4 important questions on Otolith organs (sacs) - utricle & saccule - Macula
What movement do Maculae in the utricle respond to?
What movement do Maculae in saccule respond to
The macula is made up of what specific cellular components and structures?
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
List the 5 steps in which the macula works to send static equilibrium signals to the brain?
- Hair cells of the macula are always releasing glutamate neurotransmitters
- Movement in vertical or horizontal moves changes the position of otolithic membrane in response
- Bends stereocilia and if its in the direction of kinocilia = Depol of hair cells
- Increases amount of neurotransmitter release
- More impulses travel up vestibular nerve to brain
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
