Nov 3, 2023 · The sartorius muscle is the longest muscle in the human body. Together with the quadriceps femoris, it belongs to the anterior muscles of the thigh. The sartorius muscle has an oblique course throughout the thigh; it arises from the anterior superior iliac spine, crosses to the medial side of the thigh, and finally inserts to the medial side of ...

Jan 20, 2018 · Sartorius. Long and thin, the sartorius muscle spans the distance of the thigh. It originates at anterior superior iliac spine (a bony projection on the uppermost part of the pelvis) and travels ...
Sartorius muscle. Muscles of the right leg, viewed from the front. (Rectus femoris removed to reveal the vastus intermedius.) The sartorius muscle (/ sɑːrˈtɔːriəs /) is the longest muscle in the human body. [2] It is a long, thin, superficial muscle that runs down the length of the thigh in the anterior compartment.

The sartorius muscle is a thin, long, superficial muscle in the anterior compartment of the thigh. It runs down the length of the thigh, runs over 2 joints—hip and knee joints and is the longest muscle in the human body. An exceptional length of this muscle often exceeds 50cm. In such long muscles not all muscle fibres run through the whole length ...
Sartorius derives from the Latin word sartor, meaning tailor, and it is occasionally referred to as the tailor's muscle.This name was chosen in reference to the cross-legged position in which tailors once sat.
There are slight adaptive ethnic differences in width and the range of muscle belly and tendon of the sartorius muscle.The muscle may be absent in some people.
The muscle receives 5 to 11 vessels originating from: superficial circumflex iliac, lateral femoral, deep femoral, descending geniculate, and femoral arteries.
At the hip it flexes, weakly abducts, and rotates the thigh laterally.At the knee, it can flex the leg; when the knee is flexed, it also rotates the leg medially. This muscle plays an important part in stabilisation of the pelvis—especially in women.This is due to the constrictive effect which the muscles on both sides of the body have on the pubic...
The Pes anserinus refers to the conjoined tendons of the gracilis, semitendinosus and the sartorius. It lies superficial to the tibial insertion of the medial collateral ligament of the knee. Pes anserine bursitis is a condition in which the medial portion of the knee is inflamed. If the bursa underlying the tendons of the sartorius, gracilis, and ...
Dec 14, 2022 · Sartorius. The sartorius is a muscle in the anterior compartment of the thigh. It is long and thin, running across the thigh in a inferomedial direction. Attachments: Originates from the anterior superior iliac spine (ASIS) and attaches to the superomedial aspect of the tibia. Actions: Flexion, abduction and lateral rotation at the hip joint.
The sartorius is the longest muscle in the human body and plays a crucial role in the mechanics of the lower limb. In this essay, we will explore the origin, insertion, muscle path, and function of the sartorius muscle, shedding light on its significance in human anatomy and biomechanics.

Aug 28, 2023 · The origin of the sartorius is the anterior superior iliac spine, sharing this origin with the tensor fascia lata. At the hip, it acts to both flex the hip as well as externally rotate. Other hip flexors include, most dramatically, the iliopsoas muscle and, to a lesser degree, the rectus femoris, tensor fascia lata, pectineus, adductor longus, adductor brevis, and gracilis.
