Question

What is a skeleton class 2 kids​

Answer 1

The human skeleton is a framework of 206 bones, cartilages, and ligaments that provides structure, facilitates movement, and supports the body. It is divided into axial and appendicular components with different functions for stability and mobility. Children have more bones that fuse together as they grow.

Step-by-step explanation:

A skeleton is the framework of bones that supports the body of an animal, including humans. In class 2, students learn that the human skeleton has 206 bones, which provide structure and protection for the body's organs, and assist in movement. The skeletal system also includes cartilages and ligaments. The skeleton's bones are divided into five categories based on their shapes—long, short, flat, irregular, and sesamoid, each with its own functions.

The human skeleton can be divided into two major parts: the axial skeleton, which includes the skull, spine, ribs, and sternum, and the appendicular skeleton which includes the limb bones and girdles. The lower part of the skeleton provides stability while the upper part allows for a greater range of motion to perform tasks like lifting and turning the head. Bones also store minerals, produce blood cells in the bone marrow, and protect vital organs. As children grow, some bones fuse together, which is why adults typically have 206 bones, while children have more.

Answer 2

A skeleton is the hard structure that protects the internal organs of a living thing. Skeletons can be inside the body or outside the body. In mammals, which include humans, the skeleton is made of bones. All the bones, when they are joined together, make the "skeletal system" of a body.
