JOINTS AND LIGAMENTS Flashcards
(23 cards)
What type of joint is the Coxafemoral (hip) joint?
Synovial, multiaxial, ball & socket.
What movements are allowed at the hip joint?
- Flexion
- Extension
- Abduction
- Adduction
- Medial (internal) rotation
- Lateral (external) rotation
What are the articular surfaces of the hip joint?
- Acetabulum
- Head of femur
What is the shape of the head of the femur?
2/3 sphere covered with articular cartilage.
What structure deepens the socket of the hip joint?
Acetabular labrum.
What are the three capsular ligaments of the hip joint?
- Iliofemoral ligament
- Pubofemoral ligament
- Ischiofemoral ligament
What is the function of the ligamentum teres in the hip joint?
Connects the head of the femur to the acetabulum.
What type of joint is the Tibiofemoral (knee) joint?
Synovial, biaxial, condyloid.
What movements are allowed at the knee joint?
- Flexion
- Extension
- Internal rotation
- External rotation
What are the articular surfaces of the knee joint?
- Medial femoral condyle
- Lateral femoral condyle
- Medial tibial condyle
- Lateral tibial condyle
What is a notable feature of the knee joint capsule?
Deficient anteriorly, replaced by tendon of quadriceps femoris.
What are the two types of menisci in the knee joint?
- Medial meniscus
- Lateral meniscus
What are the major ligaments associated with the knee joint?
- Fibular (lateral) collateral ligament
- Tibial (medial) collateral ligament
- Anterior cruciate ligament (ACL)
- Posterior cruciate ligament (PCL)
What is the primary function of the ACL?
Prevents anterior slide of tibia on femur.
What type of joint is the Ankle (Talocrural) joint?
Synovial, uniaxial, hinge.
What movements are allowed at the ankle joint?
- Dorsiflexion
- Plantarflexion
What are the articular surfaces of the ankle joint?
- Inferior surface of the tibia
- Trochlear surface of the talus
What are the two main types of collateral ligaments in the ankle?
- Medial collateral (deltoid) ligament
- Lateral collateral ligaments
What is the significance of inversion and eversion at the foot joints?
Allows adjustment to uneven ground surfaces and foot flexibility.
What joint classification do tarsal joints fall under?
Synovial, multiaxial.
Fill in the blank: The hip joint is classified as a _______ joint.
ball & socket
True or False: The lateral meniscus in the knee is larger than the medial meniscus.
False
What is the role of the collateral ligaments in the ankle joint?
Provide medial and lateral reinforcement to the joint capsule.
