Which term describes the inside?

Which term describes the inside?

• A. External
• B. Dorsal
• C. Internal
• D. Ventral

Answer: (C)

The key idea is distinguishing inside versus outside in anatomy. Internal describes something that is within the body's boundaries or inside a structure, such as internal organs like the heart or stomach that reside inside. External, by contrast, refers to the outside surface. Dorsal and ventral describe back and belly orientations, not inside-versus-outside, so they don’t fit this concept. Therefore, the term that best means inside is internal.
