Cranium Bones Anatomy Quiz: Test!
Can you name all the bones present in the human skull? This "Cranium Bones Anatomy Quiz" will test your knowledge regarding the different skull bones. The cranium is the part of the skull that protects the brain; it is made up of eight bones and supports the face's structure. Our cranial bones do not fuse but remain distinct and separate throughout our lives. See if you can identify the different cranial bones that are labeled in the cranium bone quiz below.
Questions and Answers
- 1.
Which bones are not fused in a child with Cleft Palate?
- A.
The palatine bones
- B.
The nasal bones
- C.
The frontal bones
- D.
The sphenoid bones
Correct Answer
A. The palatine bonesExplanation
In a child with Cleft Palate, the palatine bones are not fused. This condition occurs when the roof of the mouth does not fully close during development, resulting in a gap or opening. The palatine bones are located in the roof of the mouth and usually fuse together during normal development. However, in a child with Cleft Palate, the palatine bones remain separated, causing the cleft or gap in the palate. This can lead to difficulties with speech, eating, and other oral functions. Surgical intervention is often required to repair the cleft palate and fuse the palatine bones together.Rate this question:

If a baby's fontanelle is sunken in, what might be wrong with that baby?
- A.
They have an increased pressure in their head.
- B.
They are dehydrated.
- C.
They have a brain tumor.
- D.
All of these
Correct Answer
B. They are dehydrated.Explanation
If a baby's fontanelle is sunken in, it indicates that the baby is dehydrated. The fontanelle, also known as the soft spot on a baby's head, is normally slightly raised and firm. However, if it appears sunken, it suggests that the baby's body lacks sufficient fluids. Dehydration can occur due to various reasons, such as inadequate fluid intake, excessive sweating, vomiting, or diarrhea. It is important to address dehydration promptly in infants as it can lead to serious health complications if left untreated.Rate this question:

If a baby's fontanelle is bulging out, what might be wrong with that baby?
- A.
They have a brain tumor, which caused increased intracranial pressure in their head.
- B.
They are dehydrated.
- C.
They have a cleft palate.
- D.
All of these
Correct Answer
A. They have a brain tumor, which caused increased intracranial pressure in their head.Explanation
If a baby's fontanelle is bulging out, it could indicate increased intracranial pressure in their head. This can be caused by a brain tumor, which puts pressure on the brain and causes the fontanelle to bulge. Dehydration and a cleft palate would not directly cause a bulging fontanelle, so they are not the correct explanations. Therefore, the correct answer is that the baby has a brain tumor causing increased intracranial pressure.Rate this question:
