What is Skeleton System and its Types
The skeleton system is a complex and essential system that provides support, protection, and movement for the body. It is composed of bones, cartilage, and joints, and is responsible for a number of important functions, including:
- Support: The skeleton provides support for the body, allowing it to stand upright and move around.
- Protection: The skeleton protects the delicate organs of the body, such as the brain, heart, and lungs.
- Movement: The skeleton provides the levers and joints that allow the body to move.
- Storage: The skeleton stores minerals, such as calcium and phosphorus.
- Blood production: The bone marrow produces red blood cells, white blood cells, and platelets.
Types of Skeleton Systems
There are two main types of skeleton systems:
- Exoskeleton: An exoskeleton is a skeleton that is located on the outside of the body. Arthropods, such as insects and spiders, have exoskeletons.
- Endoskeleton: An endoskeleton is a skeleton that is located on the inside of the body. Vertebrates, such as humans, have endoskeletons.
Additional Information
- The human skeleton is made up of 206 bones.
- The longest bone in the body is the femur, or thigh bone.
- The smallest bone in the body is the stapes, or stirrup bone, in the middle ear.
- The skeleton is constantly being remodeled. Old bone is broken down and replaced with new bone.
- The skeleton is essential for life. Without it, the body would not be able to stand upright, move around, or protect its organs.
