Analyze the question stem

The question asks for the anatomical term used to describe the "soft spot" on an infant's skull. This relates to our understanding of Skeletal Anatomy and how the skull develops.

Evaluate the anatomical terms

• Suture: This is a fibrous joint that connects the bones of the skull. In infants, these are wide, but the soft spots themselves are not called sutures.
• Fontanel: This is the anatomical term for the space between the bones of an infant's skull where the sutures intersect, covered by tough membranes. These are commonly referred to as "soft spots."
• Temporal: This refers to a specific bone of the skull (the temporal bone) or the region of the temples, not a soft spot.
• Joint: While sutures are a type of fibrous joint, the specific "soft spot" itself is called a fontanel.

Confirm the correct option

Based on the anatomical definitions, the soft spot on an infant's skull is known as a fontanel.
