Question

question 10

the bones in the skull have many different names but what are the boundaries of each bone? where do they start and stop?

a. bones of the skull are separated by immobile joints called sutures.
b. boundaries for skull bones are seen only in the infant skull.
c. the boundaries are indistinct and are simply vague generalized regions.
d. bones of the skull are continuous but named for their specific markings.

Explanation:

Identify skull bone boundaries

Using the Skull Anatomy knowledge point
The bones of the skull are held together by specialized fibrous joints.

Define the joint type

Using the Joint Classification knowledge point
These immobile, interlocking joints that separate and connect skull bones are called sutures.

Evaluate the given options

• Option A correctly identifies that skull bones are separated by immobile joints called sutures.
• Option B is incorrect because sutures remain visible as boundaries in adult skulls.
• Option C is incorrect because the boundaries are distinct anatomical structures, not vague regions.
• Option D is incorrect because the bones are separate ossification centers, not a single continuous bone.

Answer:

• (A) Bones of the skull are separated by immobile joints called sutures. (Correct answer)
• (B) Boundaries for skull bones are seen only in the infant skull.
• (C) The boundaries are indistinct and are simply vague generalized regions.
• (D) Bones of the skull are continuous but named for their specific markings.
