WK No.2: Vertigo
Definition: Sensation of rotation movement either one self or surroundings
  • vertigo may represent either physiologic stimulation or pathologic dysf(x) in any of equilibrium system
Physiologic vertigo
  • miss match among 3 stabilizing sensory system
  • unfamiliar head movements in seasickness
  • unusual head position
  • following a spin
Equilibrium
-there is 2 type
  • dynamic(maintain body position in response to sudden movement)
  • static equilibrium(maintain body position relatively to force of gravity)
since she had vertigo coz of spinning...so it related wit dynamic
-for dynamic, the organ involve is crista ampulla(semicircular canal)
-when body is rotated, crista respond to changes in velocity of rotatory movement of head
-this will coz inertia, endolymh will moves to opposite direction of body rotation
-hair are bent, hair cells depolarize & impulse reach the brain at faster rate
-bending of cilia in opposite direction coz hyperpolarization & decrease impulse generation
