1.
How many percent flexible matrix are contained in the bone tissue?
Correct Answer
A. 30
Explanation
The bone tissue contains 30% flexible matrix. This means that 30% of the bone tissue is made up of a flexible matrix, which provides flexibility and resilience to the bone. The remaining 70% of the bone tissue is likely composed of minerals, such as calcium and phosphorus, which give the bone its strength and rigidity.
2.
How many percent bound minerals are present in the bone tissue?
Correct Answer
C. 70
Explanation
70% of bound minerals are present in bone tissue. This means that a significant portion of the minerals in bone tissue are bound to the bone matrix, contributing to its strength and structure. These bound minerals, such as calcium and phosphorus, play a crucial role in maintaining bone health and preventing conditions like osteoporosis.
3.
What inorganic mineral salt is bound to harden the bone matrix?
Correct Answer
A. Calcium pHospHate
Explanation
Calcium phosphate is the inorganic mineral salt that is bound to harden the bone matrix. It is an essential component of bone and helps to provide strength and rigidity to the bone structure. Calcium phosphate combines with other minerals, such as calcium hydroxide, to form hydroxyapatite crystals, which make up the majority of the bone matrix. These crystals give the bone its hardness and durability, allowing it to withstand physical stress and support the body.
4.
Which of these chemical arrangements are used in a bone matrix?
Correct Answer
A. Calcium hydroxylapatite
Explanation
Calcium hydroxylapatite is used in a bone matrix. It is a mineral compound that provides strength and rigidity to bones. It is made up of calcium and phosphate ions, which combine to form a crystal structure that gives bones their hardness. Calcium hydroxylapatite is an essential component of the bone matrix and plays a crucial role in maintaining bone health and structure.
5.
Which of these gives the bone rigidity?
Correct Answer
A. Bone mineralization
Explanation
Bone mineralization refers to the process by which minerals such as calcium and phosphate are deposited in the bone matrix, resulting in the hardening and strengthening of bones. This process is essential for providing rigidity to bones and maintaining their structural integrity. Without proper mineralization, bones would be weak and prone to fractures. Therefore, bone mineralization is the correct answer as it directly contributes to bone rigidity.
6.
Which of these is a special bone cell that assists in active construction?
Correct Answer
D. Osteoblast
Explanation
Osteoblast is a special bone cell that is responsible for the formation and construction of new bone tissue. It plays a crucial role in bone growth and repair by secreting proteins and minerals that help in the formation of bone matrix. Osteoblasts are primarily involved in the process of bone formation, making them essential for maintaining bone density and strength. They are responsible for actively building and remodeling bone, making them the correct answer in this case.
7.
How many pattern is the bone tissue woven into?
Correct Answer
A. 2
Explanation
The bone tissue is woven into two patterns.
8.
Which of these is a pattern the bone tissue can appear as?
Correct Answer
C. Cortical
Explanation
The bone tissue can appear as a cortical pattern. Cortical bone is dense and compact, forming the outer layer of bones. It provides strength and support to the skeleton. Other patterns mentioned, such as staitlaced, ring, and cancer, do not accurately describe the appearance of bone tissue.
9.
What is a Cortical bone also known as?
Correct Answer
A. Compact bone
Explanation
Cortical bone, also known as compact bone, is the hard outer layer of bone that forms a protective shell around the inner spongy bone. It is dense and strong, providing support and stability to the skeleton. This type of bone is found in the long bones of the body, such as the femur and humerus, as well as in the outer layer of other bones.
10.
Which of these other patterns of bone tissue exist?
Correct Answer
A. Cancellous Bone
Explanation
Cancellous bone, also known as spongy or trabecular bone, is one of the two types of bone tissue found in the human body. It is characterized by its porous and honeycomb-like structure, with small, interconnected spaces filled with bone marrow. Cancellous bone is typically found at the ends of long bones, in the vertebrae, and in the pelvic bones. It provides support and strength while also allowing for flexibility and shock absorption. Compact bone, the other type of bone tissue, is denser and forms the outer layer of bones. Cancer bone and ring bone are not recognized patterns of bone tissue.
