Non-striated muscles fall under which category?

Non-striated muscles are categorized as involuntary muscles. This classification is based on their function and control. Involuntary muscles operate without conscious control, which means they perform essential tasks without requiring the individual's intention to activate them. For example, non-striated muscles are found in the walls of internal organs such as the stomach and intestines, facilitating processes like digestion and peristalsis.

In contrast, voluntary muscles are those that can be consciously controlled, such as the skeletal muscles used for movement. Striated muscles, which are also referred to as skeletal muscles, have a banded appearance due to the arrangement of fibers and are under voluntary control. Cardiac muscles, while striated, are specific to the heart and also operate involuntarily. However, the clear definition that non-striated muscles are synonymous with involuntary muscles is what makes the designation clear in this context. This understanding is crucial in esthetics, particularly when considering how different types of muscle tissue affect skin and body functions.
