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.

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.

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

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.

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 of the following statements is/are correct in relation to osteoarthritis (OA)?W. Development of OA is strongly associated with articular cartilage degradation.X.  Osteophytes develop at joint margins due to stimulation of periosteal bone/cartilage formation.Y.  OA typically develops asymmetrically, and is present in most individuals over the age of 65.Z.  In OA, articular cartilage matrix loses proteoglycans and gains water; making the cartilage more susceptible to damage.Question 12Select one:a.if only W, X and Y are correctb.if only W and Y are correctc.if only X and Z are correctd.if only Z is correcte.if all are correct
