question 36

at an archeological site you discover a bone that is cylindrical in shape, about one inch long and a quarter of an inch wide. choose the correct classification.

a sesamoid
b long
c short
d irregular

Explanation:

Analyze the physical characteristics

Using the Long Bone Anatomy knowledge point
The bone is described as cylindrical in shape, about one inch long, and a quarter of an inch wide. This means its length is significantly greater than its width.

Apply bone classification criteria

Bones are classified by shape:

• Long bones: Longer than they are wide, with a shaft (diaphysis) and two ends, typically cylindrical.
• Short bones: Cube-like, roughly equal in length and width.
• Sesamoid bones: Small, round bones embedded in tendons.
• Irregular bones: Complex shapes that do not fit other categories.

A cylindrical bone that is longer than it is wide (1 inch vs. 0.25 inch) fits the definition of a long bone, regardless of its small absolute size (such as phalanges).

Answer:

• A sesamoid
• B long (Correct answer)
• C short
• D irregular
