The iliacus and nearby muscles. The hip flexors are (in descending order of importance to the action of flexing the hip joint): [2] Collectively known as the iliopsoas or inner hip muscles: Psoas major; Iliacus muscle; Anterior compartment of thigh. Rectus femoris (part of the quadriceps muscle group) Sartorius; One of the gluteal muscles ...
In human anatomy, the lower leg is the part of the lower limb that lies between the knee and the ankle. [5] Anatomists restrict the term leg to this use, rather than to the entire lower limb. [6] The thigh is between the hip and knee and makes up the rest of the lower limb. [5] The term lower limb or lower extremity is commonly used to describe ...
The femur (/ ˈfiːmər /; pl.: femurs or femora / ˈfɛmərə /), [1][2] or thigh bone, is the only bone in the thigh — the region of the lower limb between the hip and the knee. In many four-legged animals the femur is the upper bone of the hindleg. The top of the femur fits into a socket in the pelvis called the hip joint, and the bottom ...
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 anterior compartment is one of the fascial compartments of the thigh that contains groups of muscles together with their nerves and blood supply. The anterior compartment contains the sartorius muscle (the longest muscle in the body) and the quadriceps femoris group, which consists of the rectus femoris muscle and the three vasti muscles – the vastus lateralis, vastus intermedius, and ...
The biceps flexes the lower arm. The brachioradialis, in the forearm, and brachialis, located deep to the biceps in the upper arm, are both synergists that aid in this motion. Synergist muscles also called fixators, act around a joint to help the action of an agonist muscle.
In anatomy, the thigh is the area between the hip (pelvis) and the knee. Anatomically, it is part of the lower limb. [ 1 ] The single bone in the thigh is called the femur. This bone is very thick and strong (due to the high proportion of bone tissue), and forms a ball and socket joint at the hip, and a modified hinge joint at the knee.
