Which of the following structures is not a skeletal material?
Answer Details
The structure that is not a skeletal material is muscle.
Muscles are specialized tissues that are responsible for movement in animals. They are not considered skeletal materials because they do not provide structural support to the body. In contrast, chitin, cartilage, and bone are all skeletal materials that provide support and protection to different parts of the body.
Chitin is a tough, semi-transparent polysaccharide that makes up the exoskeletons of insects, crustaceans, and other arthropods. It provides structural support and protection to these animals.
Cartilage is a tough, flexible tissue that provides structural support and cushioning to joints and other parts of the body. It is found in the ears, nose, ribs, and joints of vertebrates.
Bone is a hard, mineralized tissue that provides structural support, protection, and anchorage for muscles in vertebrates. It also serves as a mineral storage site and is involved in the production of blood cells.
Therefore, the structure that is not a skeletal material is muscle, as it is not involved in providing structural support to the body.
