It runs from its two heads just above the knee to the heel, a three-joint muscle (knee,…
Semitendinosus muscle is one of four posterior thigh muscles that are responsible for extending the hip and one of three muscles that are part of the Hamstring group. The other three muscles that belong to the hip extensor group are the semitendinosus, biceps femoris, and gluteus maximus, while semimembranosus, semitendinosus, and biceps femoris are referred…
Introduction Semimembranosus is one of four posterior thigh muscles that are responsible for extending the hip, while It is also one of the three muscles to make a part of the Hamstring muscles group. The other three muscles that belong to the hip extensor group are semitendinosus, biceps femoris, and gluteus maximus. These three muscles…
Biceps Femoris Muscle Anatomy Biceps femoris is a long muscle of the posterior aspect of the thigh. Together with the semitendinosus and semimembranosus muscles, it makes the group of muscles commonly known as the hamstrings. Biceps femoris muscle runs from the ischial tuberosity, all the way to the proximal part of the fibula. In doing…
Anatomy of Gluteus Minimus Muscle The gluteus minimus is a small triangular muscle located deep in the posterior region of the hip, spanning from the gluteal surface of the ilium to the proximal end of the femur. It belongs to the group of gluteal muscles, along with the gluteus maximus, gluteus medius, and tensor fasciae…
Superficial Posterior Compartment : Gastrocnemius Muscle : Gastrocnemius forms the major bulk at the back of lower leg and is a very powerful muscle . The gastrocnemius muscle (plural gastrocnemii) is a superficial two-headed muscle that is in the back part of the lower leg of humans. It runs from its two heads just above…
Introduction Origin Insertion Glutes medius is divided into three portions similar to the deltoid muscle of the shoulder joint: Nerve Supply The gluteus medius is supplied by the superior gluteal nerve (root L4, L5, and S1). Cutaneous supply is mainly provided by L1 and 2. Blood Supply Deep branch of superior gluteal artery, trochanteric anastomosis….
Gluteus Maximus Muscle Anatomy The gluteus maximus is the main extensor muscle of the hip. It is the largest and outermost of the three gluteal muscles and makes up a large part of the shape and appearance of each side of the hips. Its thick fleshy mass, in a quadrilateral shape, forms the prominence of…
