Have you ever wondered how much work this back helps us with in our daily lives? Just think, how important these back muscles are to lift a small weight, walk, sit up straight, let's put everything else aside, and just breathe. So today, let's talk about these heroes in our back that help us without being seen, that is, the back muscles. Understanding these properly will also be a great help in keeping our back healthy.
What are back muscles? What do they do?
Simply put, the muscles in your back are a special type of muscle . In medicine, we call them ``Skeletal Muscles.'' These are the ones that provide the greatest strength to your spine and the entire middle part of your body (that is, your torso). Just think, when you stand up straight, when you sit in a chair, when you walk here and there, these muscles help with all of this. Without them, we would be like puppets, wouldn't we?
These muscles support most of your body weight. They are also essential for many of the movements we make. That's why these back muscles are more prone to injury . Problems with these muscles are a major cause of back pain for many people.
Your back muscles not only support your body, but they also help you move. In fact, they are the main structural support for your torso. These muscles help keep you stable and maintain your posture, whether you're moving or standing still.
Think of it like an automatic security system built into our bodies for your posture. Even if you don't think about it, these muscles are constantly working to keep you in the right position.
Back muscles also help move other parts of your body. For example:
- Your head
- Neck
- Shoulders
- Hands
- Legs
These muscles work together to help you bend forward, twist, turn your head, and arch your back. Surprisingly, some of these muscles in your back also help your chest rise and fall when you breathe. This is an `involuntary action` - that is, it happens automatically without your control.
How are these back muscles located? (Anatomy)
Now let's see where these muscles are located in our body and what they are connected to.
Your back muscles start under your skull . From there, they run through your shoulders and down your spine to your lower back (just above your hip bone).
These muscles are attached to various bones in your body. The main ones are:
- Single bones of the spine (`Vertebrae`): Your spine is made up of many small bones like these.
- Ribs : The bones that make up the rib cage of your chest.
- Scapulae : The two flat bones at the back of the shoulder.
These connections are what allow the back muscles to properly control your spine, shoulders, and other parts of your torso.
The back muscles are divided into three main groups! What are they?
Doctors divide these back muscles into three main groups, or `layers`, to make them easier to understand. Think of these muscles as being arranged like an onion, with one layer on top of another.
1. Superficial/Extrinsic Back Muscles:
These are the most superficial layer of muscles , just beneath the skin. They mainly help move your shoulders. When someone says "shoulder muscles," they usually think of these muscles. Some of the other major muscles in this group are:
- Latissimus dorsi : Many people call this "the lats" for short. It's one of the largest muscles in your upper body. It starts just below your shoulder blades and extends down your spine to your lower back. These muscles are very active when you're pulling something or swimming.
- Levator scapulae : These are small muscles that attach to the sides of your neck and shoulders. They help lift your shoulders.
- Rhomboids : The rhomboids connect your shoulder blades to your spine. They help pull your shoulders back and bring them together.
- Trapezius : Many people call these the "traps." These muscles start at the neck, go through the shoulders, and extend into a "V" shape down the lower back. They are very important for moving your head, neck, and shoulders.
- Serratus anterior : These muscles are located at the top of your rib cage, just below your armpits. They help to bring your shoulder blades forward and pull your chest in.
2. Intermediate Back Muscles:
This layer of muscles is located above and below your rib cage. They mainly help move your ribs. These muscles also work when you breathe. There are two muscles in this group:
- Serratus posterior superior : This muscle is located in the space between your shoulder blades (the shoulder girdle). It is located under the rhomboid muscles. It helps to lift your ribs when you breathe.
- Serratus posterior inferior : This muscle is located at the bottom of your rib cage. It sits underneath the latissimus dorsi (lats) muscles. It helps to lower your ribs when you exhale.
3. Intrinsic/Deep Back Muscles:
This is the deepest layer of the back muscles . They are located under the other two layers of muscles, close to the spine. These deep muscles are further divided into subgroups: superficial, intermediate, and deep.
This may sound a bit complicated. But to put it simply, these deep muscles are also divided into layers within themselves. For example, the "superficial" muscles in this deep group are closer to the skin than the "intermediate" muscles in the same group. The "deepest" muscles are underneath all the others. These muscles are the ones that help the spine stay straight, perform fine movements, and provide stability.
What are the muscles of the back made of?
Your muscles are made up of thousands of very fine fibers, like a rope made of many threads. When these fibers contract and stretch, your body can move.
Your back muscles are like a beautifully sewn quilt that covers your entire back. These muscles extend in many different directions. They all work together to move you and your body.
What are the common injuries that can occur to the back muscles?
The most common injury to the back muscles is a muscle strain , or what we call a "muscle pull." This happens when you overuse a muscle or lift a weight incorrectly. The delicate fibers in that muscle are stretched beyond their limits and torn.
Just think, what would happen if you tried to pull something heavy with an old, worn-out bungee cord? It would break, wouldn't it? That's what happens to muscles.
Symptoms of a back muscle disorder
When a back muscle injury occurs, symptoms such as these may usually occur:
- Muscle pain : It can be severe or gradually increasing.
- Muscle stiffness : Feeling of tightness when touched.
- Muscle weakness : A feeling of muscle weakness in that area.
- Back stiffness : Difficulty bending or straightening easily.
- Back Spasms : A feeling of sudden muscle spasms.
- Swelling : Swelling at the site of the injury.
- Bruising or skin discoloration : Sometimes the skin may turn blue.
How do doctors treat these types of disorders?
If you have a back muscle injury, a doctor will prescribe treatment based on the type of injury (and its severity). Common treatments include:
- Rest : Completely avoid the activity that caused the injury. Stay away from heavy lifting or strenuous activities until your back heals. If you exercise, your doctor will tell you how long you should stop.
- Hot/cold compresses : Apply a hot water bottle or ice pack for about 15 minutes several times a day. Sometimes your doctor will tell you to alternate between hot and cold compresses. The important thing is to wrap these in a thin cloth so that they don't touch your skin directly.
- Medication : Over-the-counter pain relievers, such as `NSAIDs` (Non-Steroidal Anti-Inflammatory Drugs) or `Acetaminophen`, can help reduce pain and swelling. However, take only as directed by your doctor, and only in the recommended dosage. Do not take pain relievers for more than 10 days at a time without medical advice.
- Physical Therapy (PT) : A physical therapist will teach you exercises and movements that will strengthen your muscles and increase your flexibility. PT can help reduce pain, improve your posture, and prevent future injuries.
How do we take care of our back muscles?
"Prevention is better than cure." This means that it is better to prevent an illness before it occurs than to treat it after it occurs. So, here are some things you can do to prevent back muscle disorders:
- Warm up and stretch your muscles before exercising. This is very important.
- Increase your overall flexibility. The more flexible your body is, the more likely it is that muscle fibers will stretch before tearing.
- Increase your exercise level gradually. Don't go overboard or lift heavy weights all at once. Don't suddenly increase the frequency or intensity of your exercise more than you normally do.
- Maintain proper posture. Keep your back straight when sitting, standing, and lifting weights. When lifting weights, bend your knees and keep your back straight.
When should we definitely see a doctor?
Usually, a minor backache will subside with a day or two of rest and home remedies. However, if your back pain doesn't subside after a week or so , you should definitely see a doctor.
Also, if you have any of these symptoms, you should go to a hospital emergency department immediately:
- Fever
- Numbness, tingling, or a feeling of weakness in the legs
- Severe pain, muscle spasms, or extreme muscle weakness
- Sudden weight loss for no reason
- Inability to control urine or stool
These symptoms indicate that something serious may be going on. So don't waste time and seek medical advice.
The most important things to remember (Take-Home Message)
You see, our back muscles are such a complex and important system. From lifting a heavy box to keeping you comfortable on the couch watching a movie, these muscles help with everything. No matter what you do, you use your back muscles without even realizing it (especially since they help you breathe!).
So, if you have back pain, don't just ignore it. It's normal to have minor aches and pains. However, if your back pain lasts for more than a week, see a doctor. Living with pain doesn't have to be a part of your daily life. A healthy back is a great foundation for a healthy life!
