Injuries to cartilage are notoriously slow-healing. Why?Multiple choice question.Cartilage is made of dense regular connective tissue, which heals poorly.Cartilage lacks a direct blood supply and relies on perichondrial blood vessels for nutrients.Cartilage is highly vascularized.Chondrocytes lack membrane channels for nutrient absorption.
Question
Injuries to cartilage are notoriously slow-healing. Why?Multiple choice question.Cartilage is made of dense regular connective tissue, which heals poorly.Cartilage lacks a direct blood supply and relies on perichondrial blood vessels for nutrients.Cartilage is highly vascularized.Chondrocytes lack membrane channels for nutrient absorption.
Solution
The correct answer is: Cartilage lacks a direct blood supply and relies on perichondrial blood vessels for nutrients.
Here's why:
-
Cartilage is a type of connective tissue in the body that has a rubbery matrix and lacks blood vessels.
-
Because it lacks blood vessels, cartilage also lacks the direct blood supply that most other tissues in the body have.
-
This lack of blood supply means that nutrients and other substances needed for healing after an injury have to diffuse through the matrix to reach the chondrocytes (the cells that make up cartilage). This process is much slower than in tissues with a direct blood supply.
-
Therefore, injuries to cartilage take longer to heal than injuries to other types of tissue
