The Skeletal System

Welcome to today’s class!!

We are thrilled to have you in our class!!

In today’s Physical and Health Education class, we will be learning about Musculoskeletal System

The Skeletal System/ Musculoskeletal System

Did you know that the skeletal system has many functions besides giving us our human shape and features? If really it does, what then is the Skeletal System?

Let’s find out!

The skeletal system is your body’s central framework. It consists of bones and connective tissue, including cartilage, tendons, and ligaments. It is also called the musculoskeletal system.

After knowing what a skeletal system is, can we now consider the functions it plays in our bodies?

These are some functions that the Skeletal System plays:

  • Allows Movement: Your skeleton supports your body weight to help you stand and move. Joints, connective tissue, and muscles work together to make your body parts mobile.
  • Produces Blood Cells: Since bones contain bone marrow. Red and white blood cells are produced in the bone marrow.
  • Protects And Supports Organs: The skull, a part of the Skeletal System, shields your brain, your ribs protect your heart and lungs, and your backbone protects your spine.
  • Stores Minerals: Bones hold your body’s supply of minerals like calcium and vitamin D.

We can also say that a skeletal system is a network of many different parts that work together to help you move. That means no movement without the Skeletal System

The main part of your skeletal system consists of your bones, the complex structures that create your body’s framework — the skeleton. 

There are 206 bones in an adult human skeleton! Interesting to know, right?

Each bone has three main layers:

  • Periosteum: The periosteum is a tough membrane that covers and protects the outside of the bone.
  • Compact Bone: Below the periosteum, compact bone is white, hard, and smooth. It provides structural support and protection.
  • Spongy Bone: The core, the inner layer of the bone is softer than compact bone. It has small holes called pores to store marrow.

The other components of your skeletal system include:

  • Cartilage: This smooth and flexible substance covers the tips of your bones where they meet. It enables bones to move without friction (rubbing against each other). 
  • Joints: A joint is where two or more bones in the body come together.

In summary, the skeletal system works as a support structure for your body. It gives the body its shape, allows movement, makes blood cells, provides protection for organs, and stores minerals. The skeletal system is also called the musculoskeletal system.
