Bone a skeletal connective tissue. It forms the framework that supports the body. Bone is a strong and nonflexible tissue made of cells called osteocytes. Bone cells are embedded in a hard matrix that is composed of calcium and phosphorus compounds. Two bones can be connected to each other by another type of connective tissue called the ligament. Another type of connective tissue associated with bone is cartilage. Cartilage smoothens bone surfaces at joints. Our nose, ear, trachea and larynx are made of cartilage.
