$\huge\mathcal\pink{\boxed{\boxed{Answer}}}$

❥Cartilage:-

• Cartilage is a flexible connective tissue found in many parts of the body.

• Cartilage is a flexible connective tissue that keeps joint motion fluid by coating the surfaces of the bones in our joints and by cushioning bones against impact.

❥Synovial Joint:-

• The six types of synovial joints are the pivot, hinge, saddle, plane, condyloid, and ball-and-socket joints. Pivot joints are found in your neck vertebrae, while hinge joints are located in your elbows, fingers, and knees. Saddle and plane joints are found in your hands.

• Synovial joints achieve movement at the point of contact of the articulating bones. Synovial joints allow bones to slide past each other or to rotate around each other.

❥Synovial fluid:-

• Synovial fluid is a viscous solution found in the cavities of synovial joints.

• The principal role of synovial fluid is to reduce friction between the articular cartilages of synovial joints during movement.

❥Patella:-

• The patella is a small bone located in front of the knee joint — where the thighbone (femur) and shinbone (tibia) meet.

• It sits in front of the knee joint and protects the joint from damage.

❥Mandible:-

• The mandible is composed of the body and the ramus and is located inferior to the maxilla.

• It holds the lower teeth in place, it assists in mastication and forms the lower jawline.

❥Cranium:-

• The cranium is located in the head and it is part of the skull together with the mandible.

• The human skull is the bony structure that forms the head in the human skeleton. It supports the structures of the face and forms a cavity for the brain. Like the skulls of other vertebrates, it protects the brain from injury.

❥Hinge Joint:-

• A hinge joint, also known as a ginglymus, is a joint in the bones of an animal or person that allows movement in one direction. Hinge joints include ankles, elbows, fingers, knees, and toes. These joints are formed when two or more bones meet and move along an axis to bend.

• A hinge joint, also known as a ginglymus, is a joint in the bones of an animal or person that allows movement in one direction. Hinge joints include ankles, elbows, fingers, knees, and toes. These joints are formed when two or more bones meet and move along an axis to bend.

❥Pivot Joint :-

• Pivot joints allow rotation, and although you have many joints in your body, there are only three pivot joints. They are located in your neck, your wrist, and your elbow.

• Pivot joint, also called rotary joint, or trochoid joint, in vertebrate anatomy, a freely moveable joint (diarthrosis) that allows only rotary movement around a single axis.

❥Ball and socket joint:-

• Examples of this form of articulation are found in the hip, where the round head of the femur (ball) rests in the cup-like acetabulum (socket) of the pelvis; and in the shoulder joint, where the rounded upper extremity of the humerus (ball) rests in the cup-like glenoid fossa (socket) of the shoulder blade.

• The joint has stabilizing ligaments that limit the directions and extent to which the bones can be moved.

❥Gliding joint:-

• Gliding joints occur between the surfaces of two flat bones that are held together by ligaments.

• Gliding joints allow the bones to glide past one another in any direction along the plane of the joint — up and down, left and right, and diagonally.
