The skeletal system is made up of cartilage, tendons, and ligaments. Which body part is also part of the skeletal system? Joints bones sweat glands skin
The skeletal system as such, is said to include all the bones and joints in your body.
The musculoskeletal system on the other hand, is a combination of the skeletal system with the muscles, cartilages, tendons etc.
In the given question, it is said that the cartilages, tendons and ligaments are a part of the skeletal system, thus from the remaining options, bones is a better answer when compared to joints, whereas sweat and skin aren’t a part of the skeletal system, hence making bones the correct answer.
