Read the below statements about connective tissues:
1. Tendous connect muscles to bones and are made of dense regular connective tissue.
2. Ligaments connect bones to bones and are slightly elastic.
3. Cartilage contains calcium salts and is harder than bone.
Which of the above statements are correct?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. Only 1 and 2 are correct.
Statements 1 and 2 are correct: Tendons are dense regular connective tissues linking muscles to bones, while ligaments connect bones to bones and possess elasticity.
However, statement 3 is incorrect. Bone is harder because its matrix is composed of calcium and phosphorus salts. In contrast, cartilage has a smooth, pliable matrix made of proteins and sugars (chondroitin salts), making it firm but much softer and more flexible than bone.
