]]>In this article we are going to study about connective tissues.
Connective tissue consist of two basic elements, the extracellular matrix and the cells. the tissue’s extracellular matrix is the material present between the spaces between the cells. the matrix consist of proteins, fibers and ground substances. the matrix vary from tissue to tissue, like cartilage’s extracellular matrix is firm but pliable and that of bone tissue has matrix hard and inflexible.
Connective tissue cells are of five types-
classification of connective tissue is based on the differences in the cells and the extracellular matrix, they are classified as-
1. What is the major function of fibroblasts?
A. secrets fibers B. stores triglycerides
C. produce histamine D. both A and C
2. What type of extracellular matrix is found in cartilages?
A. firm but not pliable B. hard and brittle
C. firm but pliable D. hard and pliable
3. Which of the following comes under loose connective tissue?
A. areolar tissue B. adipose tissue
C. reticular tissue D. all of the above
4. Match the following-
A) elastic cartilage 1. Lies in lung tissue
B) fibrocartilage 2. Lies in trachea, bronchi
C) hyaline cartilage 3. Lies in pubic symphysis
D) elastic tissue 4. In external ear
5. what is the major function of mast cells?
A. produce histamine B. kills bacteria etc
C. stores triglycerides D. secrete antibodies
6. Which of the following statement is NOT true?
A. adipocytes stores triglycerides.
B. functions of bone tissue include protection, support, storage etc
C. Hyaline cartilage lies in the external ear
d. the extracellular matrix of bone tissue is hard and brittle
7. what is the location of reticular fibers?
A. spleen B. tendons
C. ligaments D. reticular region of dermis
8. what is the main function of dense irregular connective tissue?
A. protection B. support
C. strong attachment d. none of the above
9. Where is the blood liquid tissue mainly found?
A. chambers of heart b. trachea
C. papillary region of dermis D. lymphatic vessels
10. How is the dense regular connective tissue described?
A. consist of collagen fibers arranged in bundle and fibroblasts
B. consist of collagen fibers randomly arranged
C. collagen fibers arranged in bundle and no fibroblast
D. elastic fibers present in bundles with fibroblasts.
1. secrets fibers
2. firm but pliable
3. all of the above
4. a) – 4 b) – 3 c) – 2 D) – 1
5. produce histamine
6. hyaline cartilage lies in external ear
7. spleen
8. none of the above
