Question

ordering question

click and drag on elements in order

place the steps (in order beginning at the top) involved in detecting a change in static equilibrium.

depolarization of hair cells

shift of otolithic membrane

bending of stereocilia

tilt of the head

Explanation:

Initiate physical stimulus

Using the Static Equilibrium knowledge point
When the head tilts, gravity pulls on the heavy otolithic membrane, initiating the physiological detection process.

Shift the gelatinous layer

Using the Macula Utriculi and Macula Sacculi knowledge points
The gravitational pull causes the weighted otolithic membrane to slide or shift over the underlying macula.

Deflect sensory projections

The shifting of the otolithic membrane drags the embedded stereocilia of the hair cells, causing them to bend.

Trigger electrical transduction

Bending of the stereocilia opens mechanically-gated ion channels, leading to the depolarization of the hair cells.

Answer:

1. Tilt of the head
2. Shift of otolithic membrane
3. Bending of stereocilia
4. Depolarization of hair cells
