Question

Answer

Synovial joints allows considerable movements and therefore play significant role in Locomotion.

Answer

Locomotion 11 ncert biology mein last page par clear diya hai ki synovial joints allow considerable movement.

Answer

Synovial joints..

Answer

Answer:

Synovial Joints:
Synovial joints are a type of joint that allows considerable movement and play a significant role in locomotion. These joints are characterized by the presence of a synovial cavity, which is filled with synovial fluid. The synovial fluid lubricates the joint and reduces friction, allowing for smooth movement. Examples of synovial joints include the shoulder joint, elbow joint, hip joint, and knee joint.

Fibrous Joints:
Fibrous joints, also known as immovable or fixed joints, do not allow significant movement. These joints are held together by dense connective tissue, such as collagen fibers. They provide stability and support to the body. Examples of fibrous joints include the sutures between the bones of the skull and the syndesmosis joint between the tibia and fibula.

Cartilaginous Joints:
Cartilaginous joints are characterized by the presence of cartilage between the bones. These joints allow limited movement and provide a cushioning effect. There are two types of cartilaginous joints: synchondroses and symphyses. Synchondroses joints are made of hyaline cartilage and are found in areas such as the growth plates of long bones. Symphyses joints are made of fibrocartilage and are found in areas such as the intervertebral discs and the pubic symphysis.

Role in Locomotion:
Synovial joints play a significant role in locomotion due to their ability to allow considerable movement. These joints enable us to perform various movements such as walking, running, jumping, and bending. For example, the hip and knee joints allow for the extension and flexion of the legs during walking or running. The shoulder and elbow joints facilitate the movement of the arms during activities such as throwing or lifting.

In contrast, fibrous and cartilaginous joints have limited movement and are more involved in providing stability and support to the body. While they may not directly contribute to locomotion, they play a crucial role in maintaining the overall structural integrity of the skeletal system.

Conclusion:
In summary, synovial joints are the type of joint that allows considerable movement and play a significant role in locomotion. These joints enable us to perform various movements necessary for activities such as walking, running, and bending. Fibrous and cartilaginous joints, although not directly involved in locomotion, provide stability and support to the body, contributing to the overall function of the musculoskeletal system.
