Question

In the diagram of the section of the hyaline cartilage given below, certain parts have been indicated by alphabets, choose the answer in which these alphabets have been correctly matched with the pairs which they indicate.

(a)A- blood vessel, B- Capsular matrix, C- Perichondrium, D- Lacunae, E- Chondrin, F- Chondrocytes.
(b)A- blood vessel, B- Perichondrium, C- Chondrin, D- Lacunae, E- Chondrocytes, F- Capsular matrix
(c)A- blood vessel, B- Chondrin, C- Perichondrium, D- Lacunae, E- Chondrocytes, F- Capsular matrix
(d)A- Capsular matrix, B- chondrin, C- perichondrium, D- Lacunae, E- Chondrocytes, F- blood vessels.

Answer 1

Hint: Osteoid refers to a young hyaline matrix of true bone in which calcium salts are deposited. This matrix of the cartilage is non-mineralized. The osteocytes are osteoblast cells that get trapped in the calcified matrix.

Complete answer:
Cartilage is a connective tissue that is flexible in several parts of the body. (A) point is the blood vessels that are located only in the exterior region of the cartilage. Point(B) is the perichondrium which is a fibrous layer that is formed of naive cartilage cells known as the chondroblasts. Point(C) represents chondrin which is a protein that is seen in the matrix. Point(D) is lacunae and points (E) and (F) are chondrocytes and capsular matrix respectively.

Additional Information: -Cartilage is a connective tissue which is strong but not as strong as a bines, but mildly soft and has better flexibility which makes up different areas of the human body.
-Bone connective tissue is formed by various types of bone cells such as Osteoblasts and osteocytes, in which osteocytes are involved in the production and mineralization of bone, and osteoblasts are related to the resorption of bone tissue, and calcium and minerals are deposited on it.
-Osteosarcoma or osteogenic sarcoma are malignant bone tumors which are mostly developed in adolescence during the time of high osteoid formation which is commonly called as the growth spurts.
So, the correct answer is 'A- blood vessel, B- Perichondrium, C- Chondrin, D- Lacunae, E- Chondrocytes, F- Capsular matrix'.

Note: Out of four types of cartilages, the most common one is hyaline cartilage. Yellow elastic cartilage has the elastic fibers which provide them with stretchability. Elastic cartilage is found in the eustation tube, ear lobes, epiglottis, tip of the nose.
Hyaline cartilage is seen in the sternum, larynx, ribs, trachea and etc. It is found on the many joint surfaces and makes up the fetal skeleton.
Calcified cartilage is seen in the supra-scapula of the pectoral girdle.
