Sartorius ME5 Precision Analytical Microbalance is specially designed for the highly accurate weighing of filters with dimensions up to 90 mm. Both versions are equipped with special low-profile stainless steel draft shields that keep the effects of static power to a minimum when considering filters.

The sartorius muscle ( ) is the longest muscle in the human body. It is a long, thin, superficial that runs down the length of the in the.The sartorius is also called the honeymoon muscle.Sartorius comes from the word sartor, meaning tailor, and it is sometimes called the tailor's muscle.This name was chosen in reference to the cross-legged position in which tailors once sat. In French, a muscle name itself 'couturier' comes from this specific position which is referred to as 'sitting as a tailor' (in French: 's'asseoir en tailleur').There are other hypotheses as to the genesis of the name. One is that it refers to the location of the inferior portion of the muscle being the 'inseam' or area of the inner thigh that tailors commonly measure when fitting trousers. Another is that the muscle closely resembles a tailor's ribbon.
Additionally, antique sewing machines required continuous crossbody pedaling. This combination of lateral rotation and flexion of the hip and flexion of the knee gave tailors particularly enlarged sartorius muscles. Contents.Structure The sartorius muscle originates from the and part of the notch between the anterior superior iliac spine. It runs obliquely across the upper and anterior part of the in an inferomedial direction.It passes behind the to end in a tendon. This tendon curves anteriorly to join the tendons of the and in the, where it inserts into the superomedial surface of the.Its upper portion forms the lateral border of the, and the point where it crosses marks the apex of the triangle.

Variation It may originate from the outer end of the, the notch of the, the or the.The muscle may be split into two parts, and one part may be inserted into the, the, the ligament of the or the tendon of the.The tendon of insertion may end in the fascia lata, the capsule of the, or the fascia of the leg.The muscle may be absent in some people. Function The sartorius muscle can move the hip joint and the knee joint, but all of its actions are weak, making it a synergist muscle. At the hip, it can flex, weakly abduct, and laterally rotate the thigh.
At the knee, it can flex the leg; when the knee is flexed, sartorius medially rotates the leg. Turning the foot to look at the sole or sitting cross-legged demonstrates all four actions of the sartorius. Clinical significance One of the many conditions that can disrupt the use of the sartorius is, an inflammatory condition of the medial portion of the knee. This condition usually occurs in athletes from overuse and is characterized by pain, swelling and tenderness.
The is made up from the tendons of the, semitendinosus, and sartorius muscles; these tendons attach onto the anteromedial proximal tibia. When inflammation of the bursa underlying the tendons occurs they separate from the head of the tibia.Additional images.
