Question

List the steps (in order) involved in detecting a change in static equilibrium

Shift of the otolithic membrane
Tilt of the head
Bending of the stereocilia
Depolarization of hair cells

Answer 1

The steps involved in detecting a change in static equilibrium are: tilt of the head, shift of the otolithic membrane, bending of the stereocilia, and depolarization of hair cells.

Step-by-step explanation:

1. The first step in detecting a change in static equilibrium is the tilt of the head. This causes the otolithic membrane to slide over the macula in the direction of gravity.
2. The second step is the shift of the otolithic membrane. This movement of the otolithic membrane bends the stereocilia, which are hair-like structures.
3. The third step is the bending of the stereocilia. When the stereocilia bend, it causes some hair cells to depolarize as others hyperpolarize.
4. The final step is the depolarization of hair cells. The pattern of hair cell depolarization is interpreted by the brain to determine the exact position of the head.
