The types of connective tissue in the skeletal system are , cartilage (in joints), and ligaments.

The skeletal system is primarily composed of three types of connective tissue: bone, cartilage, and ligaments.

1. Bone: This is the main structural component of the skeletal system. Bones provide support for the body, protect internal organs, and facilitate movement. They are also involved in the production of blood cells and the storage of minerals.

2. Cartilage: This is a flexible connective tissue found in many areas of the body, including the joints between bones. Cartilage acts as a cushion, reducing friction and absorbing shock in joints. It also provides structural support for certain parts of the body, such as the ears and nose.

3. Ligaments: These are bands of fibrous connective tissue that connect bones to each other. Ligaments provide stability to joints, preventing excessive movement that could lead to injury. They also help to guide the motion of the joints, ensuring that they move in the correct direction and to the correct extent.
