Ligaments are part of the Skeletal Muscular Integumentary Nervous

Ligaments are part of the **Skeletal** system. ### Explanation: - **Skeletal System**: Ligaments are strong, fibrous connective tissues that connect bones to other bones at joints. They help stabilize and support the skeletal structure, allowing for controlled movement and maintaining the integrity of joints. - **Muscular System**: This system comprises muscles and their associated structures, responsible for movement and force generation. While ligaments work closely with muscles and tendons to facilitate movement, they are not part of the muscular system. - **Integumentary System**: This includes the skin, hair, nails, and associated glands. Ligaments are not involved in this system. - **Nervous System**: Comprising the brain, spinal cord, and nerves, the nervous system is responsible for communication and control of bodily functions. Ligaments do not belong to this system. **Key Point:** Ligaments play a crucial role in the skeletal system by connecting bones and ensuring joint stability.
