Q

What are the 2 anatomical features of the tibia

Study These Flashcards
A
  • Tibial tuberosity
    -Medial Malleolus
24
Q

What is the funcion of the interosseous membrane in the tibia+fibula

Study These Flashcards
A
  • Connects the shaft of the tibia and fibula adding stability
25
What does the Fibula head articulate with
- Lateral condyle of the tibia
26
Name the 7 bones in the foot
-- Talus -Calcaneus -Navicular -Cuboid -Cuneiform -Metarsal bones -Phalanges
27
What is the most superior tarsal bone
-Talus
28
What is the largest tarsal bone
-Calcaneus
29
Explain the metatarsal bones and what it articualtes with
-Consists of 5 long bones -Their heads articulate with the phalanges
30
Explain the phalanges+ structure
- They are small long bones -Each csn be divided into distal,middle and proximal phalalnges from the 2nd to 5th bone
31
Explain the structure, location hip joint
- It is a highly mobile ball and socket joint between the proximal femur and the acetabulum of the hip bone
32
What surrounds the hip joint
- Strong fibrous capsule
33
Name the extracapsular ligaments that the joint capsule of the hip joint is reinforced by
Iliofemoral ligament -Pubofemoral and ischiofemoral ligament
34
What is the function of the acetabular labrum in the hip joint
- Deepens the joint and enhances stability
35
What are symptoms of Congenital Hip dislocation(Hip Dysplasia)
- Impaired hip abduction -And the affected limb is shorter
36
What is the cause of Hip dysplasia(Congenital Hip dislocation)
- When the femoral head is not seated in the acetabulum
37
What causes Acquired Hip dislocation
- Occurs due to trauma , causing the femoaral head to be displaced out the acetabulum
38
Name they types of Acquired Hip dislocation and their frequency
- Posterior dislocation-Most common - Anterior dislocations-Rare
39
What are key symptoma of Acquired Hip dislocation
-Sciatic nerve is vulnerable -Affected limb appaears shorter
40
Explain the structure of the knee joint + articulations
- Modified hinge joint involving: - Medial and lateral articulations between the femur and tibia -Articulation between the femur and patella
41
What movements does the knee joint have
- Flexion -Extension -Rotation -Sliding
42
What does the patella articulate with
- Femur
43
What helps with stability in the joints
- Ligaments and muscle
44
Name the 4 extrascapular ligaments in the knee joint-
-Patellar ligament -Collateral ligament -Oblique popliteal ligaments -Arcuate popliteal ligament
45
What is the function of the extracapular ligaments in the knee joint
They support the fibrous capsule
46
What is the name of the 3 intra-articular ligaments in the knee joint
- Cruciate ligaments: anterior and posterior -Transverse ligaments -Posterior meniscofemoral ligament
47
What is the function of the intra-articular ligaments in the knee joint
- Provide movement stability and orevent anterior/posterior dislocations
48
Explain the structure of the ankle joint (only the articulations)
- Includes articulations between the -Distal tibia and fibula -Talus
49
Explain the ligaments in the ankle joint
- Collateral talocrural ligaments
50
When in dorsiflexion, explain the sructure of the ankle
Ankle is tighter and more stable
51
When in plantar flexion explain the structure of the ankle joint
- Ankle is looser and stable
