Ligamentum teres limits*

A

Slightly limits adduction of hip joint

18
Q

Ligamentum teres attaches what? Enveloped by what?

A

Attaches head of femur to acetabulum

Synovial membrane envelops it as well as head and part of neck of femur

19

Q

Three separate articulations of joint and their type of joint

A

Femoropatellar- synovial gliding joint

Medial and lateral tibiofemoral – synovial hinge joint

21
Q

The capsule of the knee surrounds everything except what

A

Anterior aspect of knee- that’s why there is a suprapatellar bursa there

22

Menisci

Popliteus

25
Q

Function of ACL

A

Prevents hyper extension

26
Q
