Understanding the Medical Specialty Analogy

The question asks us to find the relationship between the first two words, 'Ophthalmology' and 'Eyes', and then apply that same relationship to the third word, 'Dermatology', to find the fourth word among the given options. This type of question tests our knowledge of vocabulary, specifically terms related to medical fields.

Analysing the Relationship: Ophthalmology and Eyes

Let's break down the relationship between Ophthalmology and Eyes:

• Ophthalmology is a branch of medicine.
• It deals specifically with the anatomy, physiology, and diseases of the eyes.
• Therefore, Ophthalmology is the medical specialty that studies and treats conditions related to the Eyes.

The relationship is: Medical Specialty : Organ/Body Part Studied/Treated.

Applying the Analogy: Dermatology and ?

Now we need to apply this same relationship to 'Dermatology'.

• Dermatology is also a branch of medicine.
• Following the pattern, Dermatology must be the medical specialty that studies and treats a specific organ or body part.
• We need to determine which organ or body part Dermatology is related to, based on the provided options.

Evaluating the Options based on Medical Specialties

Let's look at the options and see which one is studied or treated by Dermatology:

• Option 1: Nerves - The medical specialty that studies the nervous system, including nerves, is Neurology.
• Option 2: Skin - The medical specialty that studies the skin, hair, nails, and related diseases is Dermatology.
• Option 3: Bones - The medical specialty that studies bones and the musculoskeletal system is Orthopedics or Orthopaedic Surgery.
• Option 4: Brain - The medical specialty that studies the brain and nervous system is Neurology, and surgical procedures on the brain are part of Neurosurgery.

Based on this evaluation, Dermatology is the medical field related to the Skin.

Determining the Correct Answer

The analogy is Ophthalmology : Eyes :: Dermatology : ?. Since Ophthalmology is the study of Eyes, Dermatology is the study of Skin.

Therefore, the word that completes the analogy is Skin.

Summary of the Analogy

Here is a table summarizing the relationships:

The correct option is the one that lists 'Skin'.

Additional Information on Medical Terminology

Understanding prefixes and suffixes can often help in deciphering medical terms. For example:

• 'Ophthalmo-' relates to the eye.
• 'Derma-' or 'Dermato-' relates to the skin.
• '-ology' is a suffix meaning 'the study of' or 'a branch of knowledge'.

So, Ophthalmology is the study of the eye, and Dermatology is the study of the skin. This confirms our understanding of the analogy and helps build vocabulary related to various medical fields.
