The Visible Human: Transverse Section Through the ThighYou selected: rectus femorisRunning a finger from just above the knee to just below the hip approximately traces the location of the rectus femoris muscle. This muscle both extends the knee (straightens it out), and flexes the hip joint (bringing the knees into the chest). When your knee 'jumps' at the doctor's office, the reflex tested causes the rectus femoris to contract suddenly, thus causing the knee jerk.adductor magnus | gracilis | sartorius | rectus femoris | hamstring | vastus lateralis | vastus medialis | vastus intermedius | Information Module Name: a_vm2035 Module Title: The Visible Human: Transverse Section Through the Thigh Image Info: Transverse section through the leg (#2035), Visible Human Project Created by: Lynn Bry Contact Email:bryl@medicine.wustl.edu Last modified: January 16th, 1997 Created with Annotation 1.0 |
