Have you ever wondered what would happen if you didn't have muscles? Think of your muscles as the tiny engines that power your body. They are essential for everything you do—from standing, walking, and running to the vital internal processes that keep you alive. Because your muscles work so hard, injuries and health issues can be common. While some minor muscle aches resolve on their own, persistent pain or weakness might signal something more serious. At Nirogi Lanka, we recommend that if you experience muscle pain lasting longer than a week, or if you have difficulty moving, you should consult a doctor. If you ever experience difficulty breathing or swallowing, please seek emergency medical attention or call 911 immediately.
What are the functions of muscles?
Simply put, your muscles are what allow you to move your body. These movements occur in two primary ways.
Voluntary movements
These are actions you take consciously and intentionally. Think about it: when you scroll through your phone screen to read this article, or when you go for a run, these movements happen because your brain sends specific commands to your muscles. We call these voluntary movements, and they are controlled by your nervous system.
Involuntary movements
These occur automatically, without you needing to think about them. Your heartbeat, the movement of your chest muscles when you breathe, and the process of digesting food are all examples. We refer to these as involuntary movements. We simply couldn't survive without them, could we?
Beyond these two primary types of movement, your muscles play a vital role in many other functions. Consider these examples:
- Seeing
- Hearing
- Breathing, speaking, and swallowing
- Digesting food and eliminating waste (i.e., using the bathroom)
- Moving around, sitting, and standing upright
- Pumping blood through the heart and blood vessels
- Giving birth
Furthermore, muscles act as a reservoir where your body stores energy to be released when needed. This is a core component of your metabolism.
How are muscles structured?
Let's look at what muscles are made of. To be precise, a muscle is a soft tissue composed of thousands of tiny fibers bound together. Think of it like a thick rope made by bundling many smaller threads. When these fibers stretch and contract, they cause your body parts to move or your organs to function. These muscles interconnect, spreading across your body like a protective blanket. They run in different directions, working in harmony to facilitate your movement.
What are the types of muscles?
Doctors typically categorize muscles based on the type of tissue they consist of. Our bodies have three main types:
- Skeletalmuscles
- Cardiac muscle
- Smooth muscles
Skeletal muscles
These are the muscles that form part of your musculoskeletal system. They work alongside your bones, tendons, and ligaments to support your body weight and facilitate movement. Tendons are the connective tissues that attach these skeletal muscles to your bones. These are the muscles you control consciously. Some skeletal muscle fibers contract very quickly to provide short bursts of energy (these are called fast-twitch muscle fibers). Others, such as the postural muscles in your back that keep you upright, work more slowly.
Cardiac muscle
Cardiac muscle, or the myocardium, is a specialized muscle type that forms the middle layer of your heart. It is found nowhere else in the body. By contracting and relaxing, cardiac muscle pumps blood throughout your cardiovascular system. Remember, the heart is an involuntary muscle. This means it beats on its own without you needing to consciously control it.
Smooth muscles
Smooth muscles are also a type of involuntary muscle. They are found in the walls of various internal organs. For instance, smooth muscles are essential for moving waste through your intestines and allowing your lungs to expand as you breathe.
These muscles play a critical role in several bodily systems, such as:
- Female and male reproductive systems
- Urinary system
- Respiratory system
- Digestive system
How many muscles do we have?
More than you might think! We have over 600 muscles distributed throughout the body. When you think of 'muscles,' you might immediately think of the biceps in your arm or the quads in your legs. In reality, almost every part of your body relies on muscles, even the ones you aren't aware of.
What are common muscle injuries and medical conditions?
Muscle strains, commonly known as 'pulled muscles,' are the most frequent type of muscle injury. This occurs when you overuse or overextend a muscle. The muscle fibers stretch beyond their capacity and can tear—much like a worn-out bungee cord breaking under too much tension.
Additionally, there are many medical conditions that affect the muscles, including:
- Fibromyalgia
- Myopathies (diseases of the muscles)
- Myositis and polymyositis (inflammatory muscle conditions)
- Infections like Influenza and COVID-19
- Amyotrophic Lateral Sclerosis (ALS)
- Cardiovascular disease
What are the symptoms of muscle-related conditions?
If you experience a muscle injury or a related medical condition, you might notice the following symptoms:
- Muscle pain
- Muscle weakness
- Stiffness or tightness
- Muscle spasms or cramps
- Swelling
- Bruising
- Discoloration of the skin
What tests are used to identify muscle problems at Nirogi Lanka?
If your doctor suspects you are experiencing a muscle-related issue, they may recommend one or more of the following diagnostic tests:
- Blood tests
- Electromyography (EMG) (to evaluate the electrical activity of your muscles)
- Magnetic Resonance Imaging (MRI)
- Ultrasound
- Muscle biopsy (a procedure where a small tissue sample is taken for laboratory analysis)
How are muscle conditions treated?
Your treatment plan will depend entirely on the specific condition or injury you are facing. While many muscle issues resolve over time, others are chronic conditions that require ongoing management of symptoms.
For many muscle injuries, you can manage the initial healing process at home using the RICE method:
- R – Rest: Avoid activities that aggravate the injury. Give the affected area time to recover by minimizing its use.
- I – Ice: Apply an ice pack to the affected area for about 15 minutes, several times a day. Always wrap the pack in a thin towel to protect your skin from direct contact.
- C – Compression: Use an elastic bandage to wrap the injured muscle; this helps reduce swelling. Ask your doctor for the proper wrapping technique.
- E – Elevation: Whenever possible, keep the injured muscle raised above the level of your heart to facilitate blood flow and drainage.
How can I keep my muscles healthy?
The best way to prevent muscle injury is to always warm up and stretch properly before exercise. Improving your overall flexibility helps protect your muscles; the more flexible you are, the better your muscle fibers can handle strain without tearing.
Furthermore, ensure you increase your activity level gradually.Avoid sudden, intense, or prolonged exercise if your body is not accustomed to that level of exertion.
When should I see a doctor?
If you are experiencing muscle pain that does not improve after a week of rest and home care, please consult a physician. Seek emergency medical care immediately if you experience any of the following symptoms:
- Sudden chest pain or other symptoms of a heart attack.
- Difficulty breathing or swallowing.
- Severe pain, muscle spasms, or sudden muscle weakness.
- Loss of balance.
- Sudden vision changes or loss of vision.
- Inability to control your bladder or bowel movements.
Is a muscle an organ or a tissue?
A muscle is classified as tissue. While smooth muscle tissue exists within some of our organs, most organs are composed of various tissue types. Medical professionals use the term ‘muscular system’ to describe the collective body of all muscles in your body, or they may view them as integrated components within other bodily systems.
The heart is unique; it is both an organ and a muscle. It is composed of a specialized type of tissue known as cardiac muscle tissue, which is found nowhere else in your body except the heart.
What are ‘muscle groups’?
You may hear fitness trainers or physical therapists talk about ‘strengthening a specific muscle group’ or ‘targeting a muscle group during a workout.’ These classifications are typically informal.
Muscle groups are generally categorized by their location (e.g., chest muscles, leg muscles, back muscles) or by their function (e.g., abductors, which move limbs away from the body's midline, flexors, which bend a joint, or extensors, which straighten a joint).
However, medically, doctors primarily classify muscles based on the specific type of tissue they consist of.
A final note to remember
As you can see, you have over 600 muscles in your body, and they are constantly at work—whether you realize it or not. Some are visible and you can feel them (especially after a tough workout!), while others, like your heart or the muscles within your internal organs, work silently to keep you alive.
Occasional muscle soreness is a normal part of life. However, persistent or recurring muscle pain is not something to ignore. Living in constant pain is not normal. Persistent muscle discomfort is often a signal that you should have it evaluated by a doctor to ensure you receive the proper care.
Remember, staying healthy doesn't mean you have to look like a professional athlete. Talk to your doctor about the best ways to maintain your muscular and overall health. They can provide personalized advice on exercises, movements, and physical activities that will keep you strong, safe, and healthy, tailored specifically to your needs by Nirogi Lanka.
👩🏽⚕️ Frequently Asked Questions (FAQs)
💬 How many types of muscles does our body have?
The human body has three main types of muscles: 'Skeletal muscles,' which allow you to control your limb movements voluntarily; 'Smooth muscles,' which are involuntary and found in your digestive tract and internal organs; and 'Cardiac muscles,' which make up your heart.
💬 Do you strictly need meat and fish (protein) to build muscle?
Yes, muscles are primarily made of protein, which is essential for gym-goers and those looking to build muscle. However, you don't need to rely solely on meat and fish. Excellent sources of plant-based protein include lentils, chickpeas, black-eyed peas, and mung beans.
💬 What is the strongest muscle in our body?
Many people assume it is a muscle in the arms or legs. However, based on its weight, the strongest muscle in your body is the 'Masseter' (jaw muscle), which is used for chewing food.
