rectus femaur
$22.00
The rectus femoris is one of the four muscles that make up the quadriceps femoris group in the front of the thigh.
-
Location: Runs down the middle of the front thigh, between the vastus lateralis and vastus medialis.
-
Origin (Starting Point):
-
Anterior inferior iliac spine (AIIS) of the pelvis.
-
Upper rim of the acetabulum (hip joint socket).
-
-
Insertion (Ending Point):
-
Tibial tuberosity of the shinbone, via the quadriceps tendon and patellar ligament.
-
-
Function:
-
Hip flexion – helps lift the thigh upward (because it crosses the hip joint).
-
Knee extension – helps straighten the knee (main action of quadriceps).
-
-
Special Feature: Unlike the other three quadriceps muscles, the rectus femoris crosses two joints (hip and knee), so it helps in both hip movement and knee movement.
-
Clinical Note: Can be injured during activities that require explosive kicking, sprinting, or sudden hip flexion.
