Question
What are skeletal muscles? What is another name for these types of muscles? Why do scientists use this name “striated”? Where are they found? What do they do in these areas? Are they under voluntary or involuntary control?

Skeletal muscles are a type of muscle tissue that is primarily responsible for the movement of the skeleton and thus the body as a whole. They are also referred to as "striated muscles" due to their striped appearance under a microscope, which is a result of the organized arrangement of muscle fibers and myofibrils.
The term “striated” comes from the visible banding pattern observed in skeletal muscle fibers. This striation is caused by the regular alignment of actin (thin filaments) and myosin (thick filaments) within the muscle cells, which are organized into sarcomeres, the basic functional units of muscle contraction.
Skeletal muscles are found attached to bones throughout the body and are primarily responsible for facilitating voluntary movement, such as walking, lifting, and running. They play essential roles in posture, balance, and heat production through muscle contractions.
Skeletal muscles are under voluntary control, meaning that they can be consciously controlled by the nervous system. This contrasts with involuntary muscles, such as smooth and cardiac muscles, which operate automatically and are not under conscious control.
