Book Free DemoDifference between bone and cartilage:
Properties | Bone | Cartilage |
Texture | Hard | Soft |
Elasticity | Non-elastic | Elastic |
Flexibility | Tough | Flexible |
Cells | Cells are called Osteocytes | Cells are called Chondrocytes |
Matrix | It is made up of calcium and phosphate | It is made up of protein and sugar |
Function | It provides shape and structural framework to the body. And also protects the body against mechanical damage and assists in movement. | It provides support, act as a shock absorber, and provide a smooth, flexible, friction-free surface that allows our joints to work and our bones to move against each other painlessly |
Dense connective tissue:
In the previous topic, we have seen that bones act as mechanical support and facilitates movement. Now the question arises,
- How are bone linkages stable with all their movements?
- How are muscles enabling the bones for movement?
It is by means of connective tissues viz., ligaments and tendons, respectively. These tissues are made up of dense fibres and come under the category of dense connective tissues.
Dense connective tissues
It is a type of fibrous connective tissue densely packed with fibres and fibroblasts. These are the major component of tendons and ligaments.
Tendon:
Tendon is a dense connective tissue, which join skeletal muscles to bone. It has great strength and limited flexibility (inelastic). Collagen fibres are possessed in the parallel bundle, and they are present between the row of fibroblasts. 
Tendon
Function: Tendons on each side of a bone joint attach to muscles that control the movement of the joint.
Functions of tendon and ligament
Ligaments:
Two bones are connected by another type of connective tissue called a ligament. This tissue is highly elastic and has considerable strength with a low blood supply. Ligaments contain a minimal amount of matrix. 
Ligament
Functions:
- Ligaments strengthen joints and permit normal movement. Their overstretching leads to sprain (stretching or tearing of ligaments).
- Even though ligaments are slightly stretchy, they are arranged in crossing patterns to prevent the joint from becoming loose.
- Ligaments that surround the joints are to provide support and limit the joint's movement.
Do you know:
- Yellow fibres of elastin and white fibres of collagen joins together forms the matrix of protein fibre.
- Nano fibres: Sharpey's fibres, also called bone fibres, are the minute fibres of the tendon, which enter into the peristomium of bone.
- Aponeurosis is similar to tendon, but fibres are interwoven and thinner.
