Introduction

El body It is made up of more than 600 muscles that are responsible for allowing the movement of bones and internal organs. There are two main types of muscles: striated muscle and non-striated muscle. Both have specific functions in the human body and they differ in their structure and form of contraction.

Striated muscle

Striated muscle, also known as skeletal muscle, forms the majority of the muscles in the human body that connect to bones to allow movement. Striated muscle is characterized by its striated structure and its muscle cells have elongated and multinucleated shapes. This structure allows for rapid and powerful contraction of the muscle.

The striated muscle contracts voluntarily, that is, it is under the conscious control of the person. This type of muscle is mainly used to move the body, perform sports and other physical activities.

Functions of striated muscle

• Movement: Allows movement of the bones and the body in general.
• Support: Provides support and stability to bones and joints during movement.
• Toning: Helps maintain muscle shape and tone.

Non-striated muscle

Non-striated muscle, also known as smooth muscle, is found in the body's internal organs, such as the stomach, intestine, and blood vessels. Unlike striated muscle, non-striated muscle does not have a striated structure and its muscle cells are smaller and elongated.

Non-striated muscle contracts involuntarily, that is, it is not under conscious control. This type of muscle is used to perform involuntary bodily functions, such as digestion, circulation, and breathing.

Functions of non-striated muscle

• Involuntary movement: Allows the movement of internal organs and the performance of involuntary bodily functions.
• Flow and pressure regulation: Regulates the flow of fluids and gases in internal organs and maintains adequate blood pressure.
• Control of opening and closing: Controls the opening and closing of organs such as the bladder and intestine.

Conclusion

In summary, striated muscle and non-striated muscle are two different types of muscles that have specific functions in the human body. While striated muscle allows voluntary movement and physical activity, non-striated muscle performs involuntary bodily functions that are essential for maintaining life. Both types of muscles are important for the proper functioning of the human body.
