Areolar connective tissue is found between the skin and muscles, around blood vessels and nerves, in the bone marrow, and inside organs. Its functions include supporting internal organs, aiding tissue repair, and filling spaces within organs.

Cartilage has widely spaced cells and a solid matrix composed of proteins and sugars. It smoothens bone surfaces at joints and provides structure in various body parts like the nose, ear, trachea, and larynx.

Tendons connect muscles to bones, offering great strength but limited flexibility, whereas ligaments connect bones to each other and are very elastic.

Ligaments connect bones to each other, providing elasticity and considerable strength to stabilize joints.

Bone’s strength and nonflexibility are due to its hard matrix composed of calcium and phosphorus compounds. These properties provide support and protection to the body’s structures.
