Question

Regeneration of cartilage can occur from its
A. Matrix
B. Plasma
C. Perichondrium
D. All of the above

Answer 1

Hint: In certain cases, the affected cartilage is entirely removed in order to perform this operation. Articular cartilage has little regenerative capability, but the superficial layer, Ranvier's groove, intra-articular tissues like synovium and fat pad, and marrow below the subchondral bone all likely have and use intrinsic stem cell sources.

Complete Solution:
Option A: Glycosaminoglycans, proteoglycans, collagen fibers, and sometimes elastin make up the structure of cartilage. Cartilage is made up of chondrocytes, specialized cells that contain a huge volume of collagenous extracellular matrix, a field material rich in proteoglycan and elastin fibers.
So, option A is incorrect.
Option B: Plasma makes up the most of the blood. Plasma is a bright yellow liquid that separates from the other components of the blood. Plasma transports water, salts, and enzymes in the body.
So, option B is incorrect.
Option C: Since it includes mesenchymal cell-like characteristics that are progenitor cells, cartilage regeneration may occur from the perichondrium. Which allows it to go into chondrogenesis, and will aid in cartilage healing at the site of a defect.
As a result, C is the right answer.
Option D: As, we know that regeneration of cartilage is done by perichondrium.
So, option D is incorrect.

So, Option C is the correct answer.

Note:
Articular cartilage, which acts as a cushion for bone endings, is replaced by cartilage regeneration. When cartilage is weakened or broken off, bone collides with bone, causing pain near the delicate nerve endings. Since cartilage lacks a blood supply, its ability to regenerate itself is limited. While articular cartilage does not have the ability to regenerate or repair, the bone tissue beneath it does. Doctors promote new development by creating minor cuts and abrasions to the bone under the weakened cartilage.
