True or False QuestionTorn cartilage heals slowly because it lacks a direct blood supply and nutrients have to be obtained by diffusion from the blood vessels in the surrounding perichondrium.True false question.TrueFalse

Injuries to cartilage are notoriously slow-healing. Why?Multiple choice question.Chondrocytes lack membrane channels for nutrient absorption.Cartilage lacks a direct blood supply and relies on perichondrial blood vessels for nutrients.Cartilage is highly vascularized.Cartilage is made of dense regular connective tissue, which heals poorly.

Why are cartilage tissues likely to be slow in healing following an injury?Multiple ChoiceChondrocytes cannot divide.The intercellular material is semisolid.Cartilage cells are immersed in fluids.Chondrocytes do not have direct blood supplies.

Which characteristic explains the fact that bone heals much more rapidly than cartilage?Multiple choice question.Cartilage is more vascularized than bone tissue.After the injury, osteocytes convert back to osteoblasts to increase healing.Bone is more richly vascularized.

Choose the INCORRECT statement regarding articular cartilage:Question 2Answera.It is devoid of blood vesselsb.Has a covering termed the perichondriumc.Its injury is recognized as a cause of significant musculoskeletal morbidityd.Type II collagen represents 90% to 95% of the collagen in ECM and forms fibrils and fibers intertwined with proteoglycan aggregates

Identify and explain functional significance of the different cartilage components – cells, matrix, perichondrium.
