Collagen.
keratin
The nuclear matrix is made of protein and RNA fibrils.
Ligaments and tendons are made up of collagen fibers. These are very strong organic protein fibers. Weight for weight, they can be compared with steel wires.
bone matrix the intercellular substance of bone, consisting of collagenous fibers, ground substance, and inorganic salts.

There are many types of connective tissues. They all have a matrix of extracellular material and they all have cells that excrete the matrix. Tendons and ligaments are dense connective tissues, loose connective tissue tends to be found around organs. Blood and bone are also considered connective tissues.
cells, fiber, and extracellular matrix. Connective tissue is a huge part of tendons, ligaments, joints, and even muscle.
Examples of fibrous proteins include keratins, collagens and elastins. Fibrous proteins are only found in animals. Fibrous proteins form 'rod' or 'wire' -like shapes and are usually inert structural or storage proteins. They are generally water-insoluble. Fibrous proteins are usually used to construct connective tissues, tendons, bone matrix and muscle fiber.
The matrix of the bone (calcified hydroxyapatite) is non-living; the living part of the bone are the cells (osteoblasts, osteocytes, osteoclasts) and the periosteum, a tough membrane that covers the bone and allows tendons and ligaments to attach to the bone.
The space between cells can be called the extracellular space, the extracellular material, or the extracellular matrix. This space is not a vacuum; it is filled with material. If the material is gel-like it is called the ground substance, which is filled with many dissolved solute particles, and the tissue will be loose. If the material in the extracellular space has some fibers of protein in it, the entire tissue will have a stronger consistency.
Collagen is the major insoluble fibrous protein in the extracellular matrix and in connective tissue. It’s found in our muscles, bones, skin and tendons. Collagen production naturally begins to slow down as we age. Making wrinkles, sagging skin and weaker cartilage in the joints
Fibrous connective tissue is known as matrix. Matrix helps to connect joints and enables movement of the joints. If this becomes damaged, the joint or limb may become unusable.
Intercellular matrix refers to the material that is between cells. Usually this is made up of amorphous and fibrous elements.

Yes, hard but supple. There is a fine line there. When you say hard, I assume you mean tougher than muscle and skin. All tissues are held together primarily by proteins secreted by cells that surround the cells called extracellular matrix. Cells alone are generally not very sturdy. The extracellular matrix is a combination of proteins that vary depending on what part of the body and what cells are secreting the proteins. The main structural proteins are collagens and elastin which are long helical (corkscrew shaped) proteins. Tendons and ligaments have more collagen and elastin than most tissues and this is what accounts for most of their durability. The types of collagen (and other proteins) and how they are hooked together (crosslinked) also has a large effect on the properties of the tissue. For example, the durability of cartilage is also due to extracellular matrix proteins but its character is very different from tendons and ligaments because the types and associations of the proteins is different.
Collagen is a naturally occurring protein.It is found in animalls.It is a fibrous protein found in extracellular matrix and also in connective tissues.Now a days,it is used in cosmetics,to tighten the skin and to prevent wrinkles on the skin
Bone is not connective tissue. Instead, connective tissue -- ligaments and tendons -- connect to the bone.
