MUSCULUS SEMITENDINOSUS Meaning and
Definition
-
The term "musculus semitendinosus" refers to a specific muscle found in the human body. The word "musculus" is derived from Latin and translates to "muscle" in English, while "semitendinosus" is a compound word composed of two Latin terms: "semi," meaning "half," and "tendinosus," which means "sinewy" or "tendinous." Therefore, the literal translation of "musculus semitendinosus" is the "half sinewy muscle."
This muscle is located in the posterior (back) compartment of the thigh and is commonly observed in human anatomy. It is one of the three muscles that form the hamstring muscles, along with the musculus biceps femoris and musculus semimembranosus. The musculus semitendinosus is situated medially (inner side) to the biceps femoris muscle.
The semitendinosus muscle arises from the ischial tuberosity, a bony prominence in the pelvis, and descends obliquely down the thigh. It gradually narrows into a long and slender tendon towards the knee joint. This tendon ultimately inserts onto the tibia, one of the bones in the lower leg, specifically its medial (inner) and proximal (near the trunk) surface.
The main functions of the musculus semitendinosus are to flex the knee joint and extend the hip joint. It acts as a key muscle involved in movements such as walking, running, and jumping. Additionally, its tendinous structure aids in stabilizing the knee joint and preventing excessive movement during various physical activities.
