Anatomy Flashcards
Muscles that flex the hip joint
Pectineus, Iliopsoas, Rectus Femoris and Sartorius.
Muscles that extend the knee
All three heads of the quadriceps femoris- vastus lateralis, vastus medialis, vastus intermedus. And the rectus femoris.
Which muscle in the anterior compartment on the thigh runs across two joints
Rectus femoris
Name all the muscles in the anterior part of the thigh
All three heads of the quadriceps femoris- vastus lateralis, vastus medialis, vastus intermedus, rectus femoris, Pectineus, Iliopsoas and Sartorius.
Which nerve supplies the anterior compartment of the thigh
Femoral nerve (L2,3 and 4)
Name the muscles in the medial compartment of the thigh
Adductor brevis, adductor longus, adductor magnus, obturator externus and gracillis.
What is the role of the muscles in the medial compartment?
To adduct the thigh- bring it towards the medial line
The arrangement of muscles in the medial thigh
Superficially is the adductor longus. Then it is the adductor brevis. Following this
Name the proximal and distal attachments of the medial collateral and lateral collateral ligaments
Medial collateral- proximally attaches onto medial epicondyle of femur. Distally onto tibial shaft
Lateral collateral- proximally attaches onto lateral epidonyle of femur. Distally onto superior aspect of fibula head.
Name the proximal and distal attachements of the anterior and posterior cruciate ligaments
Anterior cruciate ligament- proximally onto lateral aspect of interchondylar fossa. Distally onto medial chondyle of tibia
Posterior cruciate ligament- proximally onto medial wall of interchondylar fossa and distally onto lateral chondyle of tibia.
What forms the patella ligament? where does it articulate distally?
The tendon from the quadriceps femoris. Tibial tuberosity is its distal attachment.
What is a meniscus?
Cartilage that sits on the head of the tibia in a crescent shape. It articulates in the interchondylar space.
