Question

Supportive connective tissue means
(a) Tendon
(b) Cartilage and bone
(c) Ligaments
(d) Blood and lymph

Answer 1

Hint: A connective tissue is a tissue that binds different structures of the body. It provides support to body posture and is solid, semi-rigid, and flexible tissue. A form of supportive connective tissue also contains calcium in its makeup.

Complete answer:
Bones and cartilage are supportive connective tissues. Due to their strength and durability, these tissues serve as supportive structures of the body.
Cartilage: It is a solid, semi-rigid, and flexible tissue and is formed of three parts:
1. Chondroblasts: These are oval-shaped cartilage cells that are generally present in the groups of 2-4 cells. Each cell lies in the fluid-filled space called the lacunae.
2. Matrix: It is formed of chondromyxoid, a proteoglycan (protein and carbohydrates) formed of chondroitin sulfate and albuminoid protein. It is without blood supply. It is without blood supply. The matrix is externally covered by a dense white fibrous sheet called perichondrium.
3. Fibers: It has collagen fibers.
Bone: It is solid, inflexible, hardest, and strongest connective tissue. It is formed of two types of matter, organic matter and inorganic (mineral) matter. The organic matter is formed of a protein, ossein. The inorganic matter is formed of phosphates, sulfates, carbonates, and fluorides of calcium and magnesium. The large bones are hollow inside while the smaller bones are solid.
So, the correct answer is, ‘Cartilage and bone’.

Note: Bones such as ribs and cranial bones are protective structures for critical organs such as the brain, spinal cord, heart, and lungs. Bones are relatively inflexible than cartilage. Cartilages are found in the covering the ends of long bones in the synovial joints as articular cartilages. The smooth and slippery texture of the cartilage helps minimize friction in joints.
