What is signified by the root word "Crani"?

The root word "Crani" refers specifically to the skull. This term is derived from the Greek word "kranion," which means skull. In medical terminology, prefixes and roots are often used to describe anatomical structures or conditions related to those structures. For example, terms like "cranial" relate to anything pertaining to the cranium or skull, indicating that understanding root words is essential for grasping meaningful medical vocabulary.

In this case, the other options do not share this connection. "Skin" pertains to the integumentary system, "bladder" relates specifically to the urinary system, and "cartilage" refers to a type of flexible connective tissue found in various parts of the body. Consequently, the focus on the cranial structure links the term directly to the skull, making it the correct interpretation of the root word "Crani."
