Define the following terms:
oscillating
tympanometry
orthoptic
electroretinography
aphakia
cornea

1)  OSCILLATING -  group of communicating modules

2) Tympanometry is a test that is used to assess the state of the middle ear and eardrum mobility

3) Orthoptics is a specialty affiliated with the eyecare profession that main focus is on strabism (wandering eye)

4) Electroretinography (ERG) is an eye test that measures retinal activity

5) Aphakia is the loss of the eye's lens due to surgical intervention

6) Cornea - front part of the eye

Explanation:

1) Oscillating  -  In many complex cellular processes, oscillations play a key role. They could appear as a group of communicating modules in the cell's collective dynamic behavior.

2) Tympanometry - Tympanometry is a test that is used to assess the state of the middle ear and eardrum mobility which is called tympanic membrane and conductive bones by generating changes in the ear canal's air pressure.

3) Orthoptic - Orthoptics is a specialty affiliated with the eyecare profession that main focus is on strabism (wandering eye), amblyopia (lazy eye) and eye movement disorders treatment and non-surgical management.

4) Electroretinography -  Electroretinography (ERG) is an eye test that measures retinal activity (the part of the eye that detects light).

5) Aphakia  -  Aphakia is the loss of the eye's lens due to surgical intervention, such as a perforating wound or ulcer, or congenital defect in cataract surgery.

6 ) Cornea - The part cornea is the clear front of the eye containing the iris, pupil and anterior chamber.
