A skull with squared orbit & rectangular palate with cephalic index 75 with broad nose, probably the race is.
**Question:** A skull with squared orbit & rectangular palate with cephalic index 75 with broad nose, probably the race is.
A. Mongoloid
B. Negro
C. Caucasoid
D. Mongoloid
**Correct Answer:** A. Mongoloid
**Core Concept:** Cephalic Index (CI) is a measure used to determine the shape of the skull in forensic anthropology and craniofacial anthropology. It is calculated as the ratio of the length to the breadth of the skull. A cephalic index of 75 is considered as the cut-off for categorizing skulls into different racial groups.
**Why the Correct Answer is Right:** A cephalic index of 75 or higher is considered as the cut-off for categorizing skulls into different racial groups. In this case, the skull has a squared orbit and a rectangular palate, along with a broad nose, which is characteristic of the Mongoloid race.
**Why Each Wrong Option is Incorrect:**
A. Negro (Option B): A cephalic index lower than 75 is typically found in the Negro race, with a more rounded skull shape.
C. Caucasoid (Option C): A cephalic index between 72-75 is associated with the Caucasoid race, which has a more elongated skull shape.
D. Mongoloid (Correct Answer): As mentioned earlier, a cephalic index of 75 or higher is associated with the Mongoloid race, which has a squared orbit, rectangular palate, and broad nose.
**Clinical Pearl:** Understanding cephalic index and its association with different racial groups can aid in forensic anthropology and forensic medicine, particularly during investigations involving missing persons or unidentified human remains.
