In our body, five types of joints are present namely:<\/p>\n\n- Fixed joints which do not allow movement, e.g., joints of cranium.<\/li>\n
- Ball and socket joint allow movement in all directions, e.g., joints between upper arm and shoulder, thigh and hip.<\/li>\n
- Pivotal joint allows movement in many planes, e.g., skull makes such joint with first two vertebrae.<\/li>\n
- Hinge joints allow movement only in one direction, e.g., fingers, the knee, etc.<\/li>\n
- Gliding joints allow only a limited amount of movement, e.g., joints of backbone.<\/li>\n<\/ul>\n

The bristles help to get a good grip on the ground. ‘<\/p>\nCavity:<\/strong> It is the hollow space or cavity in one bone, into which the other bone fits. Such joint allows movements in all directions.<\/p>\nGait of animals:<\/strong> Some animals do not have bones. They have muscles which help to extend and shorten the body. During movement, animal first extends the front part of the body, keeping the rear position fixed to the ground. After that animal fixes the front end and releases the rear end. Now animal shortens the body and pulls the rear end forward. During this practice, animal moves forward by a small distance.<\/p>\nClass 6 Science Ch 8 Notes<\/strong><\/p>\nRib cage:<\/strong> Ribs join with the chest bone and the backbone together to form a box.
