This writes up will explain all you need to know about how many muscles are in the human body and make you understand them well.
Before I process, I will like to put this straight to you: if you find any aspect or any statements difficult kindly read and reread again.
You must have been wondering and be willing to know the total numbers of muscles are there in the human body.
The total number of muscles in the human body is roughly estimated to 650 and they are referred to as skeletal muscles in the human body. Other muscle tissue, such as smooth muscle, typically occurs on a cellular level, which simply means one can actually have billions of smooth muscle cells.
The human body muscles are classified into three categories and they are as follows:
- Skeletal muscle
- Smooth muscle
- Cardiac muscle
The Skeletal muscle
The human skeletal muscles are attached to human bones via tendons. Each muscle is comprised of thousands of muscle fibres that are bundled together and serve similar functions in the human body.
The organised arrangement of these fibres leads to a striped pattern. Because of this, you may also refer the skeletal muscles to as striated muscle.
The Skeletal muscle is one of the predominant factors which is ultimately involved in the movement. When one of these muscles contracts, it allows movement of a specific area of the body.
The Smooth muscle cells are usually rounded at the centre and tapered off at the sides. Unlike skeletal muscle, they aren’t striated.
The term “smooth muscle” simply means the more uniform appearance of this type of muscle tissue.
The Smooth muscle as one of the types of muscle can be found in many different organ systems of your body, including but not limited to your:
- cardiovascular system
- digestive system
- respiratory system
- renal system
- reproductive system
The muscle named the cardiac muscle is found only in the human heart. It’s the type of muscle in the human body which helps human the human heart to beat well.
The type of muscle that is found in the human heart is also referred to as the myocardium.
The myocardium is one of the three layers of tissue in your heart. And it’s located between the inner lining of the heart and the protective sac that surrounds your heart (pericardium).
Similar to skeletal muscle, cardiac muscle is organised into fibres and has a striated appearance.
Individual cardiac muscle cells are closely connected to each other, which helps enable your heart to beat in a coordinated fashion.
The skeletal muscles
The Skeletal muscles can be located in all parts of the human body. Here are analyses of some of the most well-known and most used skeletal muscles, and what they do.
The functions of your skeletal muscles include:
- Generating heat, which helps maintain body temperature
- Enabling movement of the body
- Serving as an energy source during starvation
- Providing structural support
- Acting as a source of nutrients such as amino acids
- Maintaining posture
The muscles in this area control movement of the face, head, and neck. Examples include:
- Muscles of the tongue
- Eye (extraocular) muscles
This muscle is found and involved in facial expression and lifts the corners of your mouth, such as when you smile.
Muscles of the tongue
These sets of muscles assist to elevate and lower the tongue as well as help it move in and out.
This is the main muscle that’s involved when you rotate or tilt your head to the side. It’s also involved in tilting your head forward.
Eye (extracellular) muscles
This is a category of muscles that control the movements of your eyes as well as the opening and closing of your eyelids.
The Massenet is located in the jaw region area and is used to close your mouth and to chew food.
Basically, the leg is a region of the lower limb below the knee. The leg consists of the anterior, posterior, and lateral compartment.
There is no medial compartment of the leg (unlike the thigh).
The leg is innervated by branches of the sciatic nerve and receives its blood supply from branches of the political artery.
Drainage also occurs from the political vein and superficial drainage from the small and great sousaphones veins.
The anterior leg compartment consists of the following
