1.
Which of these functions does the bone tissue not perform?
Correct Answer
D. Fight Sickness
Explanation
Bone tissue does not perform the function of fighting sickness. Bone tissue is responsible for protecting organs, producing blood cells, and storing minerals. It provides structural support to the body and protects vital organs from injury. Bone marrow, found within the bones, is responsible for the production of red and white blood cells, as well as platelets. Additionally, bones store minerals such as calcium and phosphorus, which are essential for various bodily functions. However, bone tissue does not have a direct role in fighting sickness or immune response.
2.
Which of these is involved in the formation and mineralization of bones?
Correct Answer
A. Osteoclasts
Explanation
Osteoclasts are involved in the formation and mineralization of bones. They are a type of bone cell that breaks down bone tissue, allowing for the remodeling and renewal of bones. Osteoclasts play a crucial role in bone development and maintenance by resorbing old or damaged bone tissue and making way for new bone formation. They are responsible for releasing enzymes and acids that dissolve the mineralized matrix of bone, allowing for the release of calcium and other minerals. This process is essential for maintaining the strength and integrity of bones.
3.
What is involved in the resorption of bone tissue?
Correct Answer
A. Osteoclasts
Explanation
Osteoclasts are involved in the resorption of bone tissue. These specialized cells are responsible for breaking down and removing old or damaged bone tissue. They secrete enzymes and acids that dissolve the minerals in the bone, allowing them to digest and remove the bone matrix. Osteoclasts play a crucial role in maintaining bone health by regulating bone remodeling and turnover.
4.
Which of these is a bone tissue not made of? Which of these is a bone tissue not made of?
Correct Answer
D. Ostycytes
5.
What is the organic component of mainly collagen in the bone tissue called?
Correct Answer
C. Assein
Explanation
The organic component of mainly collagen in the bone tissue is called assein.
6.
What makes up the inorganic component of bone mineral?
Correct Answer
B. Salt
Explanation
The inorganic component of bone mineral is made up of salt. Salt, specifically calcium phosphate, plays a crucial role in providing strength and rigidity to bones. It helps in the formation and maintenance of bone structure, making it an essential component of bone mineral.
7.
How many types of mineralised tissue are present in the bone?
Correct Answer
B. 2
Explanation
There are two types of mineralized tissue present in the bone. These include compact bone, which is dense and forms the outer layer of the bone, and spongy bone, which is porous and found inside the bone. These two types of tissue work together to provide strength, support, and protection to the skeletal system.
8.
Which of the following is not a tissue found in the bone?
Correct Answer
D. Cyclocote
9.
What is the largest bone in the human body?
Correct Answer
A. Femur
Explanation
The femur is the correct answer because it is the largest bone in the human body. The femur, also known as the thigh bone, is located in the upper leg and is responsible for supporting the weight of the body and facilitating movement. It is a long and strong bone that connects the hip to the knee joint.
10.
What is the smallest bone in the human body?
Correct Answer
B. Stapes
Explanation
The correct answer is Stapes. The stapes bone, also known as the stirrup bone, is the smallest bone in the human body. It is located in the middle ear and plays a crucial role in transmitting sound vibrations from the eardrum to the inner ear. The stapes bone is approximately 3 millimeters in length and is shaped like a stirrup, which is where its name comes from.
