Skeleton Quiz
Your skeleton is the inner supporting system of bones that keeps you in prime shape, but it does a lot to protect your vital organs as well. What do you know about the skeleton and how it operates?
- 1.
What is the skeleton system?
- A.
All the bones in the body
- B.
All muscles and tendons
- C.
All the body's organs, both soft and hard tissue
- D.
All the bones in the body and the tissue that connects them
Correct Answer
D. All the bones in the body and the tissue that connects themExplanation
The skeleton system refers to all the bones in the body and the tissue that connects them. This includes ligaments, tendons, and cartilage. It provides support, protection, and structure to the body, allowing for movement and serving as an anchor for muscles. The skeleton system also plays a vital role in producing blood cells, storing minerals, and regulating calcium levels in the body.Rate this question:

- A.
33
- B.
206
- C.
639
- D.

Which of the following statements is INCORRECT?
- A.
Bone is where most blood cells are made
- B.
Bones serve as a wearhouse for various minerals
- C.
Bone is dry and non-living supporting structure
- D.
Bone protects and supports the body and its organs
Correct Answer
C. Bone is dry and non-living supporting structureExplanation
The given statement "Bone is dry and non-living supporting structure" is incorrect because bones are actually living tissues that contain blood vessels and cells. They are not dry and provide support to the body as well as protect organs.Rate this question:

Which bones protects the brain?
- A.
Calcium
- B.
The cranium
- C.
The cerebrum
- D.
The cerebellum
Correct Answer
B. The craniumExplanation
The cranium is the correct answer because it is the part of the skull that surrounds and protects the brain. It is a hard, bony structure that acts as a protective casing for the delicate brain tissues, shielding it from injury and trauma. The cranium is made up of several bones, including the frontal, parietal, temporal, and occipital bones, which together form a strong and sturdy enclosure for the brain. Calcium is not the correct answer because while calcium is important for bone health, it does not specifically protect the brain. The cerebrum and cerebellum are parts of the brain itself, not bones.Rate this question:

Besides the brain the skull also protects the...
- A.
The lungs
- B.
The diaphram
- C.
The body's cells
- D.
The sense organs
Correct Answer
D. The sense organsExplanation
The skull not only protects the brain but also safeguards the sense organs. The sense organs, which include the eyes, ears, nose, and mouth, are essential for perceiving and interpreting the external environment. The skull's rigid structure acts as a protective barrier for these delicate organs, preventing damage from external forces and potential injuries.Rate this question:

- A.
Protect the stomach
- B.
Protect the spinal cord
- C.
Protect the heart and lungs
- D.
Provides and object where the lungs can attach to
Correct Answer
C. Protect the heart and lungsExplanation
The rib cage is a protective structure that surrounds and encloses the heart and lungs. It acts as a barrier, shielding these vital organs from external impact and potential injuries. The ribs, along with the sternum and spine, form a strong and sturdy cage-like structure that provides support and protection to the heart and lungs, ensuring their proper functioning and preventing any damage that could be caused by accidents or trauma.Rate this question:

What makes bone so strong?
- A.
Silicia
- B.
Cartilage
- C.
Blood and marrow
- D.
Calcium and phosphorous
Correct Answer
D. Calcium and pHospHorousExplanation
Calcium and phosphorous are the main minerals that contribute to the strength of bones. These minerals provide the necessary structural support and density to bones, making them strong and rigid. Calcium is responsible for the hardness of bones, while phosphorous helps in forming the mineral matrix that gives bones their strength. Together, calcium and phosphorous work synergistically to maintain the integrity and strength of bones.Rate this question:
