Question

Two articulating bones are connected by
(a)Tendon
(b)Cartilage
(c)Ligament
(d)Fibers

Answer 1

Hint: Two articulating bones are known as joints and these joints are connected by a special connective tissue. There is another tissue present at the site of articulation known as cartilage which is responsible for providing flexibility to the joint.

Complete answer:
Two articulating bones are connected by ligaments. Ligaments are formed by the arrangement of fibrous collagen tissue. The main functions of collagen include providing support to the joints, supporting the bones, and preventing bones from grinding with each other. They do not provide complete stretchability as this would result in injury to the joints. There are approximately 900 ligaments in the human body.

Additional Information: Let us look at the type of joints present in our body.
On the basis of structure, joints are divided into 3 categories.
Fibrous joints (No movement): In these joints, as the name suggests, bones are joined by fibrous tissues. They are so strongly held that they look like they are fused. Such joints are called sutures. Example: Bones of the cranium
Cartilaginous joints (Limited movement): Again, as the name suggests these, here the bones are joined by cartilages. Example: Adjacent vertebrae are joined by like this.
Synovial joints (Considerable movement): In these joints, there is a fluid called synovial fluid between the two bones. This fluid helps reduce friction during movement. Example: Knee joint, wrist joint, etc.
So, the correct option is ‘Ligament’.

Note: -The cartilage tissue also makes up the outer structures of the ear (pinna) and the nose. This is the reason why these structures are so flexible in nature.
-A tendon is made up of a band of fibrous connective tissue and it is made up of collagen. It connects a muscle to a bone.
-Muscles are made up of long elastic fibers known as muscle fibers. These fibers are responsible for muscle contraction.
