The lubricating effects of blinking
Ans: What is an orbital defense against infection?
1-2 weeks
Ans: Older, damaged cells of the corneal epithelium are shed from the eye during
blinking or tearing. The cells is this layer are repopulated how often?
1. Fiber cells contain more cholesterol than any other than any other cell in
the human body.
2. Fiber cells produce crystallin, a protein that helps determine how well the
lens refracts light.
3. The loss of fiber cells contributes to the formation of cataracts.
Ans: What 3 things are true about the fiber cells of the lens?
Neuron ganglia
Ans: Which structures trigger aversion reflexes when potentially dangerous
intense light hits the retina?

Photoreceptor Transduction
Ans: What is the process by which rod and cone cells transform light energy into
nerve impulses?
What are characteristics of deterministic radiation effects?
Ans: 1. The severity of damage to tissue is dose dependent.
2. A dose threshold exists such that the probability of damage from low doses is
negligible.
True
Ans: True or false: radiation-induced cataracts can result from a single high dose
or from chronic low-dose exposure of the lens, which is why occupational
exposures over time represent a major concern for fluoroscopy operators.
