Jason fractured a bone in his index finger playing football, while Sean tore the cartilage in his knee playing basketball. Which one will heal faster and why?Multiple ChoiceJason; bones have a blood supply and heal faster.Jason; fingers bear less weight than knees do.Sean; cartilage has a blood supply and heals faster.Sean; knees can be immobilized easier than fingers.Jason; fingers require fewer nutrients to repair because they are small.

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.

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.

If the trochlea was fractured, what joint would be affected?Multiple ChoiceThe wrist jointThe elbow jointThe thumb jointThe shoulder joint
