What Are Different Types of Muscles In Human Body

The human muscular system includes three different types of muscles: cardiac muscle (myocardium), smooth muscle and skeletal muscle (or striatum).Our body is made up of about 640 muscles. Without them we can not live. They keep the skeleton balance and make it move. They have a important role in renewing energy, and producing heat in human body.

Skeletal Muscle

Such muscles are called, collectively skeletal muscle. They are also called voluntary muscles because, for the most part, we can choose when we want them to act and what we want them to do—drive a car. kick a football. turn a page, jump a brook, and a bicycle. Skeletal muscle also goes by two other names, based on its appearance under a microscope— striped and striated.

Smooth Muscle

There are two other general types of muscle. One is called smooth muscle because, under the microscope, it lacks the clearly defined stripes of skeletal muscle. Smooth muscle has another name, involuntary muscle, so called because the brain does not voluntarily control its actions. Smooth muscle is responsible for movements such as the muscular action that moves food and waste along the digestive tract, or the contraction and dilation of the pupil of the eye. as well as countless other involuntary movements of the sense and internal organs—with the exception of the heart.

Cardiac Muscle

The third and last general type of muscle is confined to the heart area, and is called cardiac muscle. (Cardiac means having to do with the heart.) It is involved in the rhythmic beating and contractions of the heart, which are not under conscious control, and cardiac muscle is therefore termed involuntary.

According to the movements There Are Also Types of Muscles In Human Body.

Different Types of Muscles In Human Body

The shape, location, combination with joints and bones and the disposition of the muscle fibers determine the movement that a certain muscle can perform. For example, the different muscles of the extremities can be, depending on the movement they perform:

  • Flexors : they allow flexing a joint in the sagittal plane. For example, flex the arm on the forearm.
  • Extenders : perform the movement opposite the flexors allowing to extend a joint. For example, extend the arm from the flex position.
  • Pronadores : it is a movement of rotation inwards. This movement is carried out in the transversal plane.
  • Supinators : movement of rotation towards the outside opposite to that performed by the pronator muscles.
  • Abductors : are muscles that perform movements away from the central axis of the body in the frontal plane. For example, raise the arm laterally from the shoulder.

Skeletal or skeletal muscle functions

  • They produce movement and movement of the body.
  • They protect the different organs of the body.
  • They are necessary to maintain body posture.
  • They are the body’s greatest source of heat.
  • Protect the bones.
  • Mobilizes the axial and appendicular skeleton.

Did you know?

  • The cardiac muscle beats (at rest) about 70 times per minute.
  •  To be able to say a word, the phonation and breathing organs are used, which move about 70 muscles.
  • The largest muscle of the body is the gluteus  and is located on the thigh, forming the buttock.
  •  Our muscles represent about 30% of the weight of women and 40% in men.

Muscular diseases :

  • Myopathy
  • Abssous of psoas.
  • Agujetas .
  • Arthrogryposis.
  • Atony.
  • Spinal muscle atrophy.
  • Muscular dystrophy.
  • Congenital muscular dystrophy.
  • Squint.
  • Muscular steatosis
  • Malignant hyperthermia
  • Hypotonia
  • Myopathy
  • Myalgia .
  • Temporary muscle syndrome.
  • Tetania.

I’ll provide a brief tabular format guide on the types of muscles in the human body. There are three main types: skeletal, smooth, and cardiac muscles. Here’s an overview in a simplified table format:

Type of Muscle Location Function Control Type
Skeletal Attached to bones Movement of bones and joints Voluntary
Smooth Walls of organs and blood vessels Movement of substances through organs Involuntary
Cardiac Heart Pumping blood Involuntary

Each type of muscle has distinct characteristics and functions:

  1. Skeletal Muscles: These are the muscles that you can consciously control. They are attached to your bones and are responsible for movements like walking, talking, and typing.
  2. Smooth Muscles: These muscles are found in the walls of hollow organs like your intestines, bladder, and blood vessels. They move substances through the organ, such as food through your digestive system. You cannot control these muscles consciously.
  3. Cardiac Muscle: This muscle is unique to your heart. It’s responsible for pumping blood throughout your body and, like smooth muscle, it operates involuntarily.

Remember, this is a simplified overview. Each muscle type has a complex structure and function, and there’s a lot more to learn about how they work in the human body.

Each type of muscle serves a vital purpose in maintaining our overall health and wellness. Understanding the intricacies of the human body allows us to appreciate the remarkable capabilities of these powerhouses and the importance of keeping them in optimal condition. So, the next time you take a step or feel your heart beat, remember the incredible muscles that make it all possible
