Sartorius Anna Valdman

What is the Sartorius?

The sartorius muscle is the longest muscle in the entire human body. It is a long, thin, band-like muscle found in the anterior region of the thigh. The sartorius functions as an important flexor and rotator of the thigh at the hip joint.

The Sartorius

Where is the Sartorius and how does it attach?

The sartorius muscle arises from the anterior superior iliac spine on the lateral edge of the hip bone. From the lateral hip, it descends obliquely across the hip joint and thigh, running medially and inferiorly toward the medial edge of the knee. At the knee, the sartorius turns more laterally as it descends to insert on the medial side of the tibia in the lower leg

When do you use it?

The sartorius muscle is so long that it crosses and acts upon both the hip and knee joints. Acting on the hip joint, the sartorius works as a flexor, abductor, and lateral rotator of the thigh with the assistance of the other major muscles of the hip. At the knee joint the sartorius helps to flex the leg. Combining all of these functions into one movement, the sartorius pulls the foot and ankle toward knee of the opposite leg. The action of the sartorius is used in many situations, such as crossing the legs so that the ankle rests on the knee of the opposite leg; sitting cross-legged; or looking at the sole of one’s foot.

The muscles most commonly affected by Limb-Girdle muscular dystrophy type 2A

Disease or Disorders affecting the sartorius?

Limb-Girdle muscular dystrophy type 2A: An autosomal recessive form of limb-girdle muscular dystrophy where muscle weakness and atrophy is caused by mutations of the Calpain-3 gene.

This is a disease that can affect your sartorius and when it does its hard to diagnosis since the sartorius has so many functions that you may feel pain in one place which can be misleading like pain in your knees can be so many possibilities or you can say it hurts your hip which can also mean many different things.

Muscle Facts!

-The name sartorius (from the Latin word for “tailor”) and its nickname, the “tailor’s muscle,” are derived from the common motion of tailors crossing their legs to sit while working.

-The sartorius muscle is the longest muscle in the entire human body
