Chapter 5, Problem 1DYKB

____ 1. Which tissue contains a calcified ground substance and is specialized for structural support?

1. a. muscle tissue
2. b. dense regular connective tissue
3. c. areolar connective tissue
4. d. bone connective tissue

Summary Introduction

Introduction:

Connective tissue is a type of fibrous tissue which contain insoluble matrix, in which collagen are assembled. It protects and supports the organs and the body. It also stores the energy, binds the organ together, and helps in maintaining the immunity.

Answer to Problem 1DYKB

Correct answer:

Bone connective tissue contains a calcified ground substance and is specialized for structural support. Therefore, option d. is correct.

Explanation of Solution

Reason for the correct statement:

Option d. is given as “bone connective tissue”. Bone connective tissue is hard and contains calcified matrix of collagen fibers. Its function is to support and protect the layers of muscles, and store calcium. Hence, bone connective tissue is characterized by calcified ground substances, and it provides structure and support to the body frame work.

Hence, option d. is correct.

Reasons for incorrect statements:

Option a. is given as “muscle tissue”. Muscle tissue helps in movement by contraction and it does not contain any ground substance. Hence, option a. is incorrect.

Option b. is given as “dense regular connective tissue”. Dense regular connective tissue is present in dermis of skin and contains collagen fibers and fibroblast in their structure. Hence, option b is incorrect.

Option c. is given as “areolar connective tissue”. Areolar type of connective tissue is present in subcutaneous layer of skin, and contains elastin fibers, collagen fibers, and reticular fibers. Hence, option c is incorrect.

Hence, options a, b, and c are incorrect.

Conclusion

Bones connective tissues are the connective tissue which provides support and structural frame work to the body.
