Bones are attached to each other by tendons
The ankle is the meeting point for three bones, these are the talus, tibula and fibula. Each of these three bones have their own joint that connect the foot.
The term that refers to bones sliding along each other is "gliding joint." This type of joint allows for limited motion in multiple directions.
its a ligament
A joint is where two or more bones come together and move using muscles. So a joint could be called a pivot point.
Cartilage in a joint acts as a cushion and provides a smooth surface for bones to glide over each other, reducing friction and preventing damage to the bones.
Bones interact with each other through the joints, which allow for movement. At the joint, the ends of the bones are covered with smooth cartilage that helps reduce friction. Ligaments connect the bones and provide stability, while muscles and tendons around the joint help control movement.
Tendons connect muscles to bones and help in movement, while ligaments connect bones to each other and provide stability in the knee joint.
Ligaments are the musculoskeletal structures that connect bones to each other at the joint level. They help stabilize and support the joints by encasing the joint capsule, which contains synovial fluid to lubricate the joint. Ligaments are composed of dense connective tissue, providing strength and flexibility to withstand various movements.
The reason that you cannot feel two bones rubbing together when they bend at the joint is because the two bones are separated by a layer of muscle and cartilage. It is possible for the cartilage and muscle to be torn, though, and it is possible to feel the bones rubbing together. This is very painful and in many cases will require surgery.
The articular cartilage are spongy cushions that absorb compression placed on the joint and keep the bone ends from being crushed. When the 2 bones rub against each other, they'll be rubbing on the cartilage not on the bone. If the bones really rub against each other, then you will have joint problems like osteoarthritis (swollen joint, pain).
A coating of cartilage covering the bone surface stops the bones from rubbing directly against each other. This helps the joint to work smoothly.
