Have you ever wondered how your body gets its shape, how it protects the delicate organs inside you like your heart and lungs? And who helps you move your limbs, run, and jump as you please? All of this is helped by an amazing system in our body. That is the skeletal system, or we call it ``Skeletal System`` or ``Musculoskeletal System``.
What is the Skeletal System?
Simply put, your skeletal system is the main support structure that gives your body its shape and helps hold your internal organs in place. It's like the walls of a house. But it's not just a skeleton. It's more than just bones. It's also made up of connective tissue that protects you and gives you strength when you move, muscles that help you move, and a system that makes new blood cells to keep you healthy. That's why it's sometimes called the Musculoskeletal System. It's the system that connects muscles and bones.
What services does the skeletal system provide to our body?
Our skeletal system performs several functions for our body. Some of them are easy to see and feel. But some are not, and all of them are very important for our body and health. Let's take a look at these main functions:
- Body shape: Your skeleton is the one that supports the weight of your entire body. It's also where all the other tissues in your body are attached, like the poles of a tent.
- Helping with movement: Your joints, connective tissue, and muscles all work together to move, push, and pull your body parts. Think about it, when you raise an arm or bend a leg, they all work together.
- Protecting Internal Organs: In fact, the human skeleton is like a protective suit for the organs inside our bodies. The skull on your head protects your brain. The ribs on your chest protect your heart and lungs. The vertebrae on your back protect your spinal cord. Look how important they are!
- Making new blood cells: Bone marrow, located in the center of some bones, makes new red blood cells and white blood cells that our bodies need to stay healthy. This is a very important process.
- Mineral storage: Minerals such as calcium and vitamin D, which are essential for our body, are stored inside our bones. These are released to the body when needed.
What are the main parts of the skeletal system?
When you think of a skeletal system, you probably think of the plastic skeleton you had in school science class, right? Sure, it has all your bones in it. But, there are many other types of tissue in your skeletal system. Let's take a look at what they are:
- Bones: Bones are the main supporting structure of your body. There are between 206 and 213 bones in an adult body. Each bone has a specific shape and function.
- Muscles: Muscles are made up of tightly woven, elastic fibers. There are over 600 muscles in your body. These are what help you do everything from walk, run, and jump to breathe and digest food.
- Cartilage: Cartilage is a strong, yet flexible tissue. It acts like a shock absorber in our joints. That is, it absorbs the shocks that occur when we move and jump and protects the bones.
- Ligaments: Ligaments are strong bands of tissue that connect bones to each other. These are what keep joints stable.
- Tendons: Tendons are strong, cord-like structures that connect muscles to bones. When you contract a muscle, the tendon pulls on the bone, causing movement.
- Joints: A joint is any place where two or more bones meet. It may contain some (or all) of the above-mentioned cartilage, ligaments, and other components. Joints are what allow us to bend and extend our bodies.
What are the common diseases that affect the skeletal system?
Because our skeletal system is such an important part of how we use our bodies, many common diseases and injuries can affect it. Anything that damages your bones or connective tissue can affect the skeletal system. Here are a few examples:
- Arthritis: This is when the joints become inflamed, causing pain and swelling.
- Bursitis: Inflammation of the fluid-filled sacs called bursa near the joints.
- Tendinitis: Inflammation of the tendons.
- Osteoporosis: This is a condition in which bones become thinner, less strong, and more easily broken. This condition is especially common with age.
Many autoimmune diseases affect the musculoskeletal system, especially the joints. These are diseases in which our own immune system attacks our own cells. Some of these include:
- Rheumatoid arthritis (RA)
- Psoriatic arthritis
- Lupus
- Sjögren's syndrome
Falls, car accidents, and sports injuries (traumas) often cause damage to the skeletal system. Some common injuries include:
- Sports injuries
- Bone fractures (or broken bones)
- Dislocations - bones in a joint moving out of place.
- Muscle strains (or pulled muscles)
- Ligament tears and sprains
What are the common symptoms of a skeletal system problem?
Because many diseases and injuries can affect the skeletal system, you may experience a variety of symptoms. If you have one or more of these, you should be aware of them.
- Pain: It can be muscle pain, joint pain, or bone pain. This pain can be localized or widespread.
- Stiffness/Stiffness: You may feel difficulty moving the affected area, especially in the morning.
- Swelling: We also call this `(inflammation)`. The affected area may appear swollen.
- Skin discoloration or bruising: This can be seen when there is an injury.
- Feeling hot: The area may feel hotter than other areas when you touch it. This is also a sign of inflammation.
- Difficulty moving a part of the body: This means that the range of motion that can be normally moved is reduced.
- Hearing or feeling a 'pop' or a grinding sound: This type of sound can be heard when a joint is moved.
What are the common tests performed on the skeletal system?
A doctor will recommend tests based on where you have pain or other symptoms. You may need to have tests like these:
- X-rays: These are often done to check for things like fractures and changes in joints.
- Ultrasounds: Used to look for problems with soft tissues such as muscles, tendons, and ligaments.
- CT scan (`Computed tomography (CT) scan`): This can produce more detailed images of the bones and surrounding tissues.
- MRI (Magnetic resonance imaging (MRI): This is very useful for finding problems with things like joints, cartilage, tendons, ligaments, and the spinal cord.
- Bone density test (DXA scan): This checks how strong your bones are and whether you have a condition like osteoporosis.
What are the common treatments for the skeletal system?
Unless you have an underlying illness or injury, your musculoskeletal system usually doesn't need treatment. Your doctor will determine the cause of your symptoms and recommend treatments that will help your body heal. Some of these include:
- Medications: You can take medications such as NSAIDs (nonsteroidal anti-inflammatory drugs) such as ibuprofen, naproxen, and acetaminophen (paracetamol) to reduce pain and swelling. Sometimes your doctor may prescribe corticosteroids or medications specific to an autoimmune disease.
- Immobilization: After an injury, you will often need to wear a brace, splint, sling, or cast. This helps to immobilize the injured area and help it heal. Your doctor will tell you what kind you need and how long you should wear it.
- Physical therapy: A physical therapist can help you strengthen muscles, increase flexibility, and reduce pain, especially after an injury or surgery.
- Joint replacement (Arthroplasty (joint replacement): Some people, especially those with severe arthritis, may need to have part or all of their joints replaced. Hips and knees are the most common. Your doctor or surgeon will tell you more about this.
How can I keep my skeletal system healthy?
Following a healthy diet (rich in calcium and vitamin D) and an exercise plan that suits you will help keep your bones (and overall) healthy. Also, by going for regular medical checkups, you can quickly identify any problems or symptoms that affect your skeletal system.
Follow these general safety tips to reduce the risk of injury:
- Always wear your seat belt when driving. Definitely!
- Wear safety equipment for any activity or sport, such as a helmet and knee pads.
- Stretch, warm up, and cool down before and after strenuous physical activity. This will reduce the risk of muscle and joint injuries.
- Keep your home and workplace free of unnecessary items that could trip you or others. Don't leave things on the floor.
- Always use the right tools or equipment to reach things that are high up in your home. Never climb on chairs, tables, or counters. Use something like a small ladder.
- If you have difficulty walking or are at high risk of falling, use a cane or walker. It's not embarrassing, it's important to be safe.
Finally, take-home message:
Your skeletal system is like the frame that holds your entire body together. Whether you're a world-class athlete or someone sitting on the bus reading this article on their phone, you're constantly using your bones, muscles, and connective tissue.
Remember, if you experience any new pain, stiffness, or other symptoms, be sure to see a doctor. He or she will be able to explain what is causing these symptoms and how you can get back to your normal activities. Taking care of your body is the most important thing!
