What Do You Know About Eyelashes? - Quiz

We all know what eyelashes are but what else do you know about them than the fact that they are sensitive to touch and they are the whiskers of human beings?

Questions and Answers

1.

Eyelashes are found on the...
- A.
  
  Pupil
- B.
  
  Eyelid
- C.
  
  On the forehead
- D.
  
  Eyebrow
Correct Answer
B. Eyelid

Explanation
Eyelashes are found on the eyelid. The eyelid is the thin fold of skin that covers and protects the eye. Eyelashes are hair follicles that grow along the edge of the eyelid. They serve to protect the eye from debris, such as dust and dirt, and also help to prevent sweat and other fluids from entering the eye. Additionally, eyelashes can enhance the appearance of the eye and play a role in nonverbal communication, such as blinking and winking.

- A.
  
  Protect
- B.
  
  Open
- C.
  
  Close
- D.
  
  Open and close
Correct Answer
A. Protect

Explanation
Eyelashes help to protect the eyes by acting as a barrier against dust, debris, and other particles that may enter the eye. They also help to reduce the amount of light that enters the eye, preventing excessive brightness and potential damage. Additionally, eyelashes can trigger the blink reflex, which helps to keep the eyes moist and prevent them from drying out. Overall, eyelashes play a crucial role in safeguarding the eyes and maintaining their health.

- A.

Explanation
The growth of eyelashes is divided into three stages.

Rate this question:
4.

The active growth period of eyelashes is called the _____ phase.
- A.
  
  Catagen
- B.
  
  Growth
- C.
  
  Anagen
- D.
  
  Telogen
Correct Answer
C. Anagen

Explanation
The active growth period of eyelashes is called the Anagen phase. During this phase, the hair follicles are actively producing new cells, resulting in the growth of longer and thicker eyelashes. This phase can last for several weeks to several months, and it is the phase where the majority of eyelash growth occurs.

Rate this question:
5.

Catagen phase is a/an ____ stage.
- A.
  
  Active growth
- B.
  
  Transitional
- C.
  
  Open
- D.
  
  Resting
Correct Answer
B. Transitional

Explanation
The catagen phase is a transitional stage in the hair growth cycle. During this phase, the hair follicle shrinks and detaches from the dermal papilla, causing the hair to stop growing. It is a short period of time between the active growth phase (anagen) and the resting phase (telogen). During catagen, the hair follicle undergoes structural changes and prepares for the next stage of the cycle. This transitional phase is essential for the renewal and regeneration of the hair follicle.

Which of these tiny living things lives in the eyelashes?
- A.
  
  Plasmodium
- B.
  
  Amoeba
- C.
  
  Termites
- D.
  
  Demodex
Correct Answer
D. Demodex

Explanation
Demodex is a type of tiny living organism that lives in the eyelashes. These mites are commonly found in the hair follicles and oil glands of the eyelids. They are microscopic in size and are usually harmless, but in some cases, they can cause irritation and inflammation of the eyelids, leading to a condition known as demodicosis. Regular cleaning of the eyelids and proper hygiene can help prevent the overgrowth of Demodex mites.

The function of the human eyelashes can be compared to the structure on the...
- A.
  
  Tail of a rat
- B.
  
  Hair on a dog
- C.
  
  Whiskers on a cat
- D.
  
  Tail of a dog
Correct Answer
C. Whiskers on a cat

Explanation
The function of human eyelashes can be compared to the structure of whiskers on a cat. Both serve as sensory organs that help in detecting potential threats and obstacles in the environment. They are also involved in protecting the eyes from dust, debris, and other foreign particles. Like whiskers, eyelashes are sensitive to touch and can trigger a reflexive blinking response to protect the eyes from potential harm.

Rate this question:
8.

A disease which causes the loss of the eyelashes is called...
- A.
  
  Blepharitis
- B.
  
  Distichiasis
- C.
  
  Madarosis
- D.
  
  Trichiasis
Correct Answer
C. Madarosis

Explanation
Madarosis is the correct answer because it refers to a condition where there is loss or absence of eyelashes. It can be caused by various factors such as certain medical conditions, infections, trauma, or as a side effect of certain medications. Blepharitis is a condition characterized by inflammation of the eyelids, but it does not specifically cause loss of eyelashes. Distichiasis is a condition where there is an abnormal growth of eyelashes, while trichiasis refers to the condition where eyelashes grow inwards towards the eye, both of which are not related to the loss of eyelashes.

Rate this question:
9.

Which of these is true about the upper and lower eyelashes?
- A.
  
  Upper lashes are fuller than lower lashes
- B.
  
  Lower lashes are fuller than upper lashes
- C.
  
  Upper lashes are more sensitive than lower lashes
- D.
  
  Lower lashes are more sensitive than upper lashes
Correct Answer
A. Upper lashes are fuller than lower lashes

Explanation
Upper lashes are fuller than lower lashes because the upper eyelid contains more hair follicles than the lower eyelid. This results in a greater density and thickness of lashes on the upper lid compared to the lower lid.

10.

Which of these is a disorder that urges the sufferer to pull out eyelashes?
- A.
  
  Trichotillomania
- B.
  
  Distichiasis
- C.
  
  Blepharitis
- D.
  
  Madarosis
Correct Answer
A. Trichotillomania

Explanation
Trichotillomania is a disorder characterized by the irresistible urge to pull out one's own hair, including eyelashes. It is classified as an impulse control disorder and can lead to hair loss and distress. Distichiasis is a condition where extra eyelashes grow on the inner surface of the eyelid, but it is not associated with the urge to pull out eyelashes. Blepharitis refers to inflammation of the eyelids and Madarosis refers to the loss of eyelashes, but neither of these conditions specifically involve the compulsion to pull out eyelashes.
