The two main tissues responsible for structural support in the body are called the compact bone and the ligaments.
The Compact bone is a dense bone in which the bony matrix is solidly filled with organic ground substance and inorganic salts, leaving only tiny spaces (lacunae) that contain the osteocytes, or bone cells.
A Ligament is a fibrous connective tissue that connects bones to other bones. It also supports the internal organs.
