What is the main function of rectus femoris?
The rectus femoris is a biarticulate muscle, meaning it passes over two joints: the knee and hip. Its main function is as a knee extender; however, the proximal attachment at the anterior inferior iliac spine and the acetabulum allows for this muscle to act as a hip flexor as well.

What does rectus femoris mean in anatomy?
quadriceps muscle
: a division of the quadriceps muscle lying in the anterior middle region of the thigh, arising from the ilium by two heads, inserted into the tuberosity of the tibia by a narrow flattened tendon, and acting to flex the thigh at the hip and with the rest of the quadriceps to extend the leg at the knee.
Where is rectus femoris muscle?
thigh
The rectus femoris is a long, fleshy muscle located in the anterior compartment of the thigh. The rectus femoris is fusiform in shape with superficial fibers that are bipenniform and deep fibers that run straight (rectus) to the deep aponeurosis.
What is the function of rectus abdominis?
