Skeletal System II Exam Prep Quiz!
While our organs, the respiratory system, and the cardiovascular system are some of the features of the human body that keep us ticking away as intended, the skeletal system is what provides us with shape and form, allowing us to put all of those processes mentioned above to fair use and do something with our lives. What can you tell us about the skeletal system? Take the quiz!
- 1.
The skeletal system consists of:
- A.
Bone, cartilage, ligaments, tendons, adipose, epithelia, and nerves
- B.
Bone, cartilage, ligaments, haversian systems, osteons, and endomysium
- C.
Bone, tendons, adipose, ramus, meatus, and sulcus
- D.
None of the above
Correct Answer
A. Bone, cartilage, ligaments, tendons, adipose, epithelia, and nervesExplanation
The skeletal system consists of bone, cartilage, ligaments, tendons, adipose, epithelia, and nerves. This is because the skeletal system is not just composed of bones, but also includes other connective tissues like cartilage, ligaments, and tendons. Adipose tissue is also present in the skeletal system, providing cushioning and insulation. Epithelial tissue lines the surfaces of bones and other structures within the skeletal system. Nerves are also a part of the skeletal system, allowing for communication and coordination between different parts of the body.Rate this question:

An ellipsoid joint has a flat articulating surface and permits all motions except for rotation.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
An ellipsoid joint does not have a flat articulating surface. Instead, it has an oval-shaped articulating surface that allows for a wide range of motions, including rotation. Therefore, the statement that an ellipsoid joint permits all motions except for rotation is incorrect.Rate this question:

Fill in the Blanks: The type of bone that is only found in the sutures of fetal skulls is called __________.
- A.
Wormian
- B.
No other answer
Correct Answer(s)
A. Wormian
B. No other answerExplanation
The type of bone that is only found in the sutures of fetal skulls is called "wormian". This term refers to small extra bones that can develop within the sutures of the skull. No other answer is correct because "wormian" specifically describes this unique type of bone found in fetal skulls.Rate this question:

Matching: Click on the pairs that are matched correctly.
- A.
Compact bone - lamellae
- B.
Compact bone - haversian systems
- C.
Hyaline cartilage - vascular
- D.
Chondroycytes - lacunae
- E.
Sesamoid - ligaments
Correct Answer(s)
A. Compact bone - lamellae
B. Compact bone - haversian systems
D. Chondroycytes - lacunaeExplanation
The correct answer is that compact bone is matched correctly with lamellae and haversian systems, and chondrocytes are matched correctly with lacunae. Compact bone is composed of lamellae, which are concentric rings of mineralized matrix that surround the central haversian systems. Haversian systems are cylindrical structures that contain blood vessels, nerves, and bone cells. Chondrocytes are the cells found in cartilage, and they reside within small spaces called lacunae.Rate this question:

How many bones are there in the average person's body?
- A.
33
- B.
206
- C.
639
- D.
It varies by the individual
Correct Answer
B. 206Explanation
The human skeletal system consists of 206 bones (including the three tiny bones in each middle ear).Rate this question:

What makes bones so strong?
- A.
Silica
- B.
Cartilage
- C.
Blood and marrow
- D.
Calcium and phosphorous
Correct Answer
D. Calcium and phosphorousExplanation
Calcium and phosphorous are minerals that give bones their strength. People must obtain these minerals from food. People who do not get enough of these minerals have brittle bones and they may become stooped when they grow old.Rate this question:

What is the difference between cartilage and bone?
- A.
Bone is rubbery, and cartilage is firm.
- B.
Bone is a more primitive tissue than cartilage.
- C.
Cartilage is rubbery, and bone is firm.
- D.
Bone is inside the body, and cartilage is outside.
Correct Answer
C. Cartilage is rubbery, and bone is firm.Explanation
Cartilage is a more flexible and softer material than bone. It serves as a protective, cushioning layer where bones come together -- preventing them from rubbing against one another. Cartilage also makes a firm but flexible framework for the ear and respiratory passages, ensuring that these openings do not collapse.Rate this question:

Muscles are made of:
- A.
Silica
- B.
Polyester threads
- C.
Calcium and phosphorous
- D.
Groups of cells called fibres
Correct Answer
D. Groups of cells called fibresExplanation
Muscles are made up of many cell fibers joined together. These fibers can expand and contract, allowing the parts of the body to move.Rate this question:

What is the function of the skeletal system?
- A.
Support the body
- B.
Give the body shape
- C.
Work with muscles to move the body
- D.
All of the above
Correct Answer
D. All of the aboveExplanation
The skeletal system has multiple functions. It provides support to the body, giving it shape and structure. Additionally, it works in conjunction with the muscles to facilitate movement and locomotion. Therefore, the correct answer is "all of the above" as all the given options accurately describe the functions of the skeletal system.Rate this question:
