What type of muscle is the Sartorius?

The Sartorius muscle is classified as skeletal muscle. Skeletal muscle is a type of striated muscle that is under voluntary control, meaning it can be consciously controlled by the nervous system. The Sartorius is the longest muscle in the human body and is located in the thigh. It plays a significant role in movements such as flexing the hip and knee and helps with crossing the legs.

Skeletal muscles, including the Sartorius, are characterized by their striated appearance due to the arrangement of actin and myosin filaments. This striated pattern is a hallmark of skeletal and cardiac muscle but is not present in smooth muscle, which lacks the striations and is involuntary in nature. While it is true that skeletal muscle is striated, the terminology used in this context leads to the most accurate classification being skeletal muscle for the Sartorius.
