The spongy substance that prevents bones from grinding against each other at their joints is called cartilage. This flexible, rubbery tissue acts as a cushion, absorbing shock and allowing for smooth movement between bones. It helps reduce friction and provides support, ensuring that joints function properly during physical activities.

Bones are light because they are hollow inside and filled primarily with marrow, a spongy substance which produces new red blood cells in large bones.
They are kind of like shock absorbers, and prevent bones from grinding against each other.
Spongy
No If your bones are grinding against each other you really need to go see a bone specialist.
No. Flat bones consist of spongy bone sandwiched between compact bone.
The spongy bone in adults is located in the epiphyses of long bones, as well as in the interior of flat bones such as the sternum, ribs, and skull. This spongy bone is also referred to as trabecular or cancellous bone, and it provides structural support and flexibility to bones.
Bone marrow is the substance that is found at the core of bones, and is either made of fat or red blood cells depending on the type of bone in question. For spongy bone, the marrow is made of red blood cells.
Spongy bone contains bone marrow and is 'softer" in the center.

Spongy bone has a lattice-like structure with open spaces filled with bone marrow. This design makes spongy bone lightweight and flexible, allowing it to absorb shock and distribute forces in multiple directions. This structure also provides space for blood vessels and facilitates the exchange of nutrients and waste products.
