Functions, Movements of body parts, Stability and Posture, Heat production, Circulation, Muscular system has the following important functions in human body;. Human muscle system, the muscles of the human body that work the skeletal system, that are under voluntary control, and that are concerned with movement. As you have probably guessed, the main function of the muscular system is movement, but it also helps stabilize our joints, maintain our posture and generate heat during activity. Movement of our body can be voluntary and controlled by the skeletal muscles, or it can be involuntary and controlled by smooth muscles.

It muscular system functions the teeth to close with a force of up to 55 pounds on the incisors or pounds on the molars. Below is a 3-D model of the muscular system, which is fully interactive.

Explore the model, using your mouse pad or touchscreen, to understand more about the muscular system.

Muscular System

Takeaway Muscles play a part in all functions of the muscular system functions, from heartbeat and breathing to running and jumping.

When muscles become damaged, it can impact movement, speech, and much more. They help us in all kinds of movements, such as walking, swimming, writing and even talking.

All this movement is aided by the anatomy and organization of the muscular system. But, before we move on, we should mention you do have muscular system functions other type of muscle in your body.


Cardiac muscles are found in the heart muscular system functions are responsible for the movement of blood through your body. Muscle Anatomy First, let's take a brief look at the muscles themselves. Like so many other things, muscles are made up of lots of smaller parts.

Muscular System: Facts, Functions & Diseases

We'll start at the level of the muscular system functions fiber. A muscle fiber is simply a muscle cell, or the building blocks of muscles.

See, just like the rest of muscular system functions body is made up of lots and lots of individual cells, your muscles are also made up of cells. Multiple fibers join together to make up our next level of organization, the fascicle.

What Is the Muscular System? - Function & How Muscles Work in Groups

A fascicle is a group, or bundle, of muscle fibers. Cardiac muscles are exclusively found in human heart and no where else. They are extremely strong and powerful muscles.

They are not under the control of human will and are involuntary. The pumping of blood by human heart is muscular system functions of the force provided by the contraction of cardiac muscles.

11 functions of the muscular system: Diagrams, facts, and structure

The muscle that produces any particular movement of the body is known as an agonist or prime mover. The agonist always pairs with an antagonist muscle that produces the opposite effect on the same bones.

For example, the biceps brachii muscle muscular system functions the arm at the elbow.

As the antagonist for this motion, the triceps brachii muscle extends the arm at the elbow. When the triceps is extending the arm, the biceps would be considered the muscular system functions.

Synergists are muscles that help to stabilize a movement and reduce extraneous movements. They are usually found in regions near the agonist and often connect to the same bones.

What are the main functions of the muscular system?

Because skeletal muscles move the insertion closer to the immobile origin, fixator muscles assist in movement by muscular system functions the origin stable. If you lift something heavy with your arms, fixators in the trunk region hold your body upright and immobile so that you maintain your balance while lifting.

Skeletal Muscle Histology Skeletal muscle fibers differ dramatically from other tissues muscular system functions the body due to their highly specialized functions. Many of the organelles that make up muscle fibers are unique to this type of cell.

The sarcolemma is the cell membrane of muscle fibers.

The sarcolemma acts as a conductor for electrochemical muscular system functions that stimulate muscle cells. Connected to the sarcolemma are transverse tubules T-tubules that help carry these electrochemical signals into the middle of the muscle fiber.

Myofibrils are made up of many proteins fibers arranged into repeating subunits called sarcomeres.
