Read the below statements about connective tissues: 1. Tendons 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?
Only 1 and 2 are correct
Examine each statement:
1 (correct): Tendons attach skeletal muscles to bones and are made of dense regular connective tissue (parallel collagen fibres) for high tensile strength along the muscle's pull.
2 (correct): Ligaments connect bone to bone at joints. They contain mostly collagen with some elastic fibres, making them slightly elastic to allow controlled joint movement while maintaining stability.
3 (incorrect): Cartilage is made primarily of collagen fibres in a chondroitin-sulphate matrix and does not contain calcium salts (that's bone). Cartilage is therefore softer and more flexible than bone, not harder.
Hence only statements 1 and 2 are correct — option (1).
