Articular cartridge
Synovial membrane
Articular capsule
What is/are the functions of synovial fluid? (3)
Lubricates
Absorbs shock
Helps deliver nutrients to cartridge cells

B) muscles
C) cartridge and bone
D) bone and muscle
A) bones
Match the word to definition
- Plane joint
- Saddle joint
- Ball and socket joint
- Chondylar joint
- Pivot joint
- Hinge joint
A) Uniaxial joint in which the rounded articular surface of one bone fits into the groove of another bone and is held into place by a ligamentous ring
B) Multaxial joint in which the spherical articular surface of one bone fits into a cup or socket of another bone
C) Non-axial joint in which two flat surfaces glide over each other
D) Uniaxial joint in which the convex articular surface of one bone fits into a concave articular depression
E) biaxial joint in which the oval, convex articulating surface of one bone fits into the shallow depression of another bone
F) Biaxial joint in which each articular surface as both convex and concave regions
1-c 2- f 3- b 4-e 5-a 6-d
True or false:
A) the knee and elbow are multiaxial joint
B) the elbow joint consists of two separate articulations
C) The patella is encased within the tendon of the quadriceps femoris muscle group
D) The shoulder joint is stabilized by the medial and lateral menisci
E) The hip joint is less stable than the shoulder joint, but it allows more motion.
A) false, the knee and elbow are uniaxial
B) true
C) true
D) false, knee joint is stabilized by the medial and lateral menisci
E) false, the hip joint is more stable then the shoulder joint but it has less motion then the shoulder joint
What is the function and full name of the acl, pcl, lcl and mcl
Acl- anterior cruciate ligament —> prevents anterior movement of tibia
Pcl- posterior cruciate ligament—>prevents posterior movement of tibia
Lcl - lateral/fibular collateral ligament —> prevents medial movement of tibia
Mcl - medial/tibial collateral ligament—> prevents lateral movement of tibia
The shoulder and hip joints are both similar because they are both
A) ball and socket joints
B) hinge joints
C) biaxial joints
D) uniaxial joints
A) ball and socket joints
What factors contribute to the stability of the hip joint?
The acetabulum is relatively deep, which allows the femoral head to fit inside snugly. The fit is enhanced by the acetabular labrum, the articular capsule and multiple ligaments

Ligaments, tendons, muscle tone, bursa(e), tendon sheath
______ is a fluid filled sack located between a tendon and bony surface to reduce friction
______ matters because the stronger you are the more stable your joints will be
_______ connect bone to bone
________connect muscle to bone
________ covers a tendon and protects from friction like a bursa
Bursa(e)
Muscle tone
Ligaments
Tendons
Tendon sheath
