Do you know these things about the muscles in your body? Let's talk!

Have you ever wondered what would happen to us if we didn't have the muscles in our body? These muscles are actually like little engines in our body. These muscles help us move, stand, run, jump, and perform many other functions inside our body. However, because muscles work so hard, they are also prone to injuries and diseases. Sometimes a little muscle pain comes and goes and gets better on its own. But if there is persistent muscle pain or weakness, it can be a sign of something serious. Therefore, if you have muscle pain for more than a week, if you have difficulty moving, see a doctor. If you have difficulty breathing or swallowing, you should go to the hospital immediately.

What are the functions of muscles?

Simply put, muscles are what help us move our bodies around. These movements occur in two main ways.

Voluntary movements

These are the things you do consciously and intentionally. Think about it, when you scroll up and down on your phone to read this article, or when you run, all of this happens because your muscles are activated by a command from your brain. We call these voluntary movements . These are controlled by our nervous system .

Involuntary movements

These are things that happen automatically, without your control. Things like your heart beating, the muscles in your chest contracting when you breathe, and the way you digest food. We call these involuntary movements . We couldn't live without them, right?

In addition to these two main movements , our muscles help with many other things. Take a look:

• To see
• To ask
• To breathe, to speak, to swallow
• To digest food and eliminate waste (i.e., urination and defecation)
• Move around, stay in one place, stand up straight.
• Pump blood through the heart and blood vessels
• To give birth to a child

Additionally, muscles are where our bodies store energy and release it when needed . This is part of our metabolism.

How are muscles formed?

Okay, now let's see what these muscles are made of. To be precise, a muscle is a soft tissue made up of thousands of tiny `` fibers '' that are strung together. It's like a big rope made up of many tiny threads. When these fibers stretch and contract (contract), our body parts move, or our organs function. These muscles are connected to each other, like a blanket that wraps around our bodies. They run in different directions, and they work together to move us.

What are the types of muscles?

Doctors usually classify muscles according to the type of tissue they are made of. There are three main types of muscles in our bodies:

• Skeletal muscles
• Cardiac muscle
• Smooth muscles

Skeletal muscles

These are the muscles that are part of our musculoskeletal system. They work with our bones, tendons , and ligaments to support our weight and move us around. These skeletal muscles are attached to the bones by tendons. These are the muscles that we control consciously, that is, the muscles that we use voluntarily. Some skeletal muscle fibers contract very quickly and use short-term force (these are called fast-twitch muscles) . Others, for example, the muscles in our back that help us keep our body upright, work slowly.

Cardiac muscle

The heart muscle, or myocardium, is a special type of muscle that makes up the middle layer of our heart. It is found only in the heart, not anywhere else in the body. This heart muscle contracts and expands to pump blood through our cardiovascular system. Remember, the heart is an involuntary muscle. This means that it beats on its own, without any control from you.

Smooth muscles

Smooth muscles are also a type of involuntary muscle. They are found in the inner walls of some of the organs inside our bodies. For example, smooth muscles perform many essential functions, such as moving waste through our intestines and helping our lungs expand when we breathe.

These smooth muscles play an important role in many of our body's systems, for example:

• Female and male reproductive systems `(Female reproductive system and male reproductive system)`
• Urinary system
• Respiratory system
• Digestive system

How many muscles do we have in our body?

More than you think! There are over 600 muscles in our bodies. When you think of 'muscles', you might think of the biceps in your arms or the quads in your thighs. But, in reality, almost every part of our body is supported by muscles. Some of them we never even know about.

What are the common injuries and conditions that affect muscles?

Muscle strains, or as we say , 'nerves are twisted'That's the most common muscle strain. It happens when we overuse a muscle. Then those muscle fibers I mentioned before get stretched beyond their limits and get torn. You've probably seen what happens when you tie something up with an old bungee cord, that's what happens.

In addition, there are many different medical conditions that affect the muscles. Here are a few examples:

• Fibromyalgia
• Myopathies (muscle diseases)
• Myositis and polymyositis (inflammation of the muscles)
• Infections like influenza and COVID-19
• Amyotrophic Lateral Sclerosis (ALS)
• Cardiovascular disease

What are the symptoms related to muscle pain?

If you have a muscle injury or other medical condition, you may experience symptoms like these:

• Muscle pain
• Muscle weakness
• Stiffness, tightness
• Muscle spasms or cramps
• Swelling
• Bruises
• Skin discoloration

What tests are used to diagnose muscle problems?

If a doctor thinks you have a muscle problem, they may do some tests, such as:

• Blood tests
• Electromyography (EMG) (this measures the electrical activity of the muscles)
• Magnetic Resonance Imaging (MRI)
• Ultrasound scan `(Ultrasound)`
• Muscle biopsy (a small piece of muscle is taken and examined)

How are muscle problems treated?

The type of treatment you need will depend on the condition or injury you have. Some muscle problems get better over time, while others are chronic conditions (meaning you need to manage your symptoms for a long time).

Many times, muscle injuries can be managed at home using the RICE method . RICE stands for:

• R - Rest: Avoid the activity that caused the injury. Try not to use the injured part of the body until it heals.
• I - Ice: Apply an ice pack to the injured area for about 15 minutes several times a day. Wrap the ice pack in a thin cloth or towel to prevent direct contact with the skin.
• C - Compression: Wrap an elastic bandage around the injured muscle to reduce swelling. Ask your doctor how to do this properly.
• E - Elevation: Keep the injured muscle above the level of your heart whenever possible.

How can I keep my muscles healthy?

The best way to avoid muscle injuries isWarming up and stretching before exercising. Increasing your overall flexibility also protects your muscles from injury. The more flexible your body is, the more likely it is that muscle fibers will stretch before tearing.

Also, increase your activity level gradually. Don't suddenly start exercising harder or for longer periods of time than you're used to.

When should I see a doctor?

If you have muscle pain that doesn't go away after a week of rest and other home remedies, be sure to see a doctor. Also, go to the hospital immediately if you have any of the following symptoms:

• Sudden chest pain or other heart attack symptoms.
• Difficulty breathing or swallowing.
• Severe pain, muscle twitching, or muscle weakness.
• Loss of balance.
• Sudden loss of vision.
• Inability to control urination or defecation.

Is a muscle an organ or a tissue?

Muscle is a tissue . Smooth muscle tissue is found inside some of our organs, but many organs are made up of other types of tissue. Doctors sometimes refer to the 'muscular system' as a single body system that includes all the muscles in our body. Otherwise, they consider muscles to be parts of other systems throughout the body.

The heart is the only organ that is also a muscle. It is made up of a special type of muscle tissue called cardiac muscle tissue. The only place in your body that has cardiac muscle tissue is in the heart.

What are 'muscle groups'?

You've probably heard fitness trainers or physical therapists talk about things like 'I need to strengthen this muscle group', 'I need to exercise this muscle group'. These are usually not very strictly defined.

Muscles are often grouped according to where they are located (for example, chest muscles, leg muscles, back muscles) or the type of movement they perform (for example, abductors ( muscles that move the body away from the midline), flexors ( muscles that bend a joint), or extensors ( muscles that extend a joint)).

However, doctors usually classify muscles only by the type of tissue they are made of.

Finally, something for you to remember.

You see, we have over 600 muscles in our bodies, and we use them all the time, whether we think about them or not. Some muscles we can see and feel (especially after a good workout!), while others – like our heart and the muscles inside some organs – keep us alive without making a sound.

It's normal to feel aches and pains sometimes. But if you have muscle pain all the time, that's not a good thing. It's not normal to be in pain all the time. Muscle pain can often be a sign of a condition that needs to be diagnosed and treated by a doctor.

Remember, you don't have to look like a professional athlete to be healthy. Talk to your doctor about ways to maintain your muscle (and overall) health. They can recommend exercises, movements, or physical activities that are right for you and will keep you strong, safe, and healthy.
