Question

The appendicular skeleton in an adult consists of:

• A. 126 bones
• B. 206 bones
• C. 80 bones
• D. 120 bones

Answer 1

The Correct Option is A

Step 1: Recall the total bone count.
The adult human skeleton has 206 bones in total.

Step 2: Split into axial and appendicular parts.
The skeleton is divided into the axial skeleton (skull, vertebral column, ribs, sternum) and the appendicular skeleton (limb bones and the girdles that attach them). The axial skeleton accounts for 80 bones.

Step 3: Subtract to find the appendicular count.
\[ 206 - 80 = 126 \]

Step 4: Final Answer.
\[ \boxed{126 \text{ bones}} \]
