How Knowledgeable Are You About Bones? - Quiz

Bones are an important part of the skeletal system. All bones are known as the white, hard solid structure protecting vital organs. Each part of the body has unique bones well connected to muscles and ligaments to make it function properly. Bones can be flat, irregular or short. How much do you know about this?

Questions and Answers

1.

Which of these is not a function of bones?
- A.
  
  Production of erythrocytes
- B.
  
  Production of leucocytes
- C.
  
  Storage of minerals
- D.
  
  Maintainance of the acid-base balance
Correct Answer
D. Maintainance of the acid-base balance

Explanation
Bones do not play a direct role in the maintenance of the acid-base balance in the body. This function is primarily carried out by the kidneys, which regulate the levels of acids and bases in the blood. Bones are responsible for other functions such as production of red and white blood cells, storage of minerals like calcium and phosphorus, and providing structural support to the body.

2.

What type of tissue is the bone?
- A.
  
  Epithelial tissue
- B.
  
  Connective tissue
- C.
  
  Nervous tissue
- D.
  
  Muscle tissue
Correct Answer
B. Connective tissue

Explanation
Bones are classified as connective tissue because they are composed of cells embedded in a matrix of collagen fibers and mineral salts. Connective tissue provides support and structure to the body, and bones specifically serve as the framework for the body, protect internal organs, and aid in movement.

3.

What type of bone cells are involved in the resorption of bone tissue?
- A.
  
  Osteoblasts
- B.
  
  Osteoclasts
- C.
  
  Cancellous bone
- D.
  
  Cortical bone
Correct Answer
B. Osteoclasts

Explanation
Osteoclasts are involved in the resorption of bone tissue. These cells are responsible for breaking down and removing old or damaged bone tissue. They secrete enzymes that dissolve the minerals in the bone and release them into the bloodstream. Osteoclasts also play a role in regulating calcium levels in the body.

4.

Which of these tissues is not found in bones?
- A.
  
  Endosteum
- B.
  
  Periosteum
- C.
  
  Nerves
- D.
  
  Fibers
Correct Answer
D. Fibers

Explanation
Fibers are not found in bones. Bones are composed of various tissues such as endosteum, periosteum, nerves, and fibers. However, fibers are not a component of bone tissue. Instead, fibers are found in other connective tissues such as tendons and ligaments.

5.

What is the total amount of bones in a newborn?
- A.
  
  239 bones
- B.
  
  270 bones
- C.
  
  289 bones
- D.
  
  285 bones
Correct Answer
B. 270 bones

Explanation
A newborn baby typically has 270 bones. This is because babies are born with more bones than adults, as some of their bones have not yet fused together. As the baby grows and develops, some of these bones will fuse, resulting in a total of 206 bones in adulthood.

Rate this question:
6.

What is the total number of separate bones in an adult?
- A.
  
  210 bones
- B.
  
  206 bones
- C.
  
  230 bones
- D.
  
  290 bones
Correct Answer
B. 206 bones

Explanation
An adult human body has a total of 206 separate bones. These bones make up the skeletal system, which provides structure, support, and protection to the body. The skeletal system also allows for movement and produces blood cells. The bones in the body vary in size and shape, ranging from small bones in the hands and feet to larger bones in the arms, legs, and torso. It is important to note that the number of bones can vary slightly from person to person due to the presence of extra bones or the fusion of certain bones during development.

Rate this question:
7.

Which of these is not a type of bone?
- A.
  
  Long bones
- B.
  
  Sesamoid bones
- C.
  
  Short bones
- D.
  
  Coral bones
Correct Answer
D. Coral bones

Explanation
Coral bones are not a type of bone found in the human body. Long bones, short bones, and sesamoid bones are all types of bones that exist in the skeletal system. However, coral bones are not a recognized category of bones.

Rate this question:
8.

Which of these is an example of short bones?
- A.
  
  Carpal bones
- B.
  
  Wrist bone
- C.
  
  Patella
- D.
  
  Sternum
Correct Answer
B. Wrist bone

Explanation
The wrist bone, also known as the carpal bones, is an example of short bones. Short bones are typically cube-shaped and provide support and stability to the body. The carpal bones are located in the wrist and play a crucial role in allowing for a wide range of movements in the hand and wrist joints. They are made up of small, compact bones that are designed to withstand pressure and absorb shock.

9.

Which of these is an example of sesamoid bones?
- A.
  
  Patella
- B.
  
  Tibia
- C.
  
  Sternum
- D.
  
  Sphenoid bones
Correct Answer
A. Patella

Explanation
The patella, also known as the kneecap, is an example of a sesamoid bone. Sesamoid bones are small, round bones that are embedded within tendons. They are typically found in areas where tendons pass over joints, such as the patella, which lies within the tendon of the quadriceps muscle and protects the knee joint. The tibia, sternum, and sphenoid bones are not examples of sesamoid bones.

What is the smallest type of bone in the human body?
- A.
  
  Tibia
- B.
  
  Femur
- C.
  
  Stapes bone
- D.
  
  Carpal bones
Correct Answer
C. Stapes bone

Explanation
The stapes bone is the smallest bone in the human body. It is located in the middle ear and is part of the ossicles, a group of three bones that transmit sound vibrations from the eardrum to the inner ear. The stapes bone, also known as the stirrup bone, is approximately 2.5 to 3.3 millimeters in length and plays a crucial role in the process of hearing. Its small size allows for efficient transmission of sound waves, contributing to our ability to perceive and interpret sound.

- A.
  
  Tibia
- B.
  
  Femur
- C.
  
  Stapes bone
- D.
  
  Carpal bones
Correct Answer
C. Stapes bone

Explanation
The stapes bone, also known as the stirrup bone, is the smallest bone in the human body. It is one of the three bones in the middle ear and plays a crucial role in transmitting sound vibrations from the eardrum to the inner ear. Its small size allows it to fit within the tiny space of the middle ear and contribute to the process of hearing.
