Question 19

In medical terminology, the prefix "Omo - " is related to the shoulder. For example, "omohyoid" is a muscle related to the shoulder and hyoid bone. The other options: "back of the head" has prefixes like "occipito - ", "palm of the hand" has prefixes like "palm - " or "thenar - ", and "chest" has prefixes like "thoraco - ". So "Omo - " means shoulder.

We analyze each term:

• "dys/chrondro/plasia": "dys - " means abnormal, "chrondro - " means cartilage, "plasia" means formation, so it's abnormal cartilage formation, not related to calcium/lime build - up.
• "ankyl/osis": "ankyl - " means stiffening, "osis" is a condition, it refers to stiffening of a joint, not calcium build - up.
• "calcin/osis": "calcin - " is related to calcium, "osis" is a condition, so it means abnormal build - up of calcium (lime is calcium - based) in tissues.
• "omoburs/itis": "omo - " is shoulder, "burs - " is bursa, "itis" is inflammation, so it's inflammation of the shoulder bursa, not related to calcium build - up.

Answer:

A. shoulder
