The muscles that are under our control called voluntary muscles.
The muscles that are not under our control called involuntary muscles.

Test for Difference between Involuntary and Voluntary Muscles

In the human body, muscles play a crucial role in movement and maintaining the structure of the skeletal system. Muscles are categorized into two main types: involuntary and voluntary muscles. To understand the difference between these two types of muscles, a test can be conducted. Here's how you can perform the test:

Materials Needed:
- A mirror
- A pen or marker

Procedure:

1. Stand in front of a mirror and observe your body movements.

2. Identify different muscle actions and determine whether they are voluntary or involuntary.

Key Differences:

Involuntary Muscles:
- Involuntary muscles are also called smooth muscles or non-striated muscles.
- These muscles are found in various parts of the body, including the digestive system, blood vessels, and respiratory system.
- They are responsible for carrying out automatic functions like digestion, blood circulation, and breathing.
- Involuntary muscles work involuntarily without conscious control.
- They are not under our direct control and work automatically to maintain the body's homeostasis.
- Examples of involuntary muscles include the muscles in the walls of the stomach, intestines, and blood vessels.

Voluntary Muscles:
- Voluntary muscles are also known as skeletal muscles or striated muscles.
- These muscles are attached to the bones of the skeletal system and are responsible for various voluntary movements.
- They are under conscious control and allow us to perform actions like walking, running, and writing.
- Voluntary muscles work in coordination with the nervous system to generate movement.
- They are connected to the bones by tendons and provide stability and support to the skeletal system.
- Examples of voluntary muscles include the muscles in the arms, legs, and face.

Conclusion:

By observing your body movements and identifying the muscle actions, you can differentiate between involuntary and voluntary muscles. Involuntary muscles work automatically without conscious control and are responsible for essential functions, while voluntary muscles are under our conscious control and enable us to perform voluntary movements.
