Joints and vertebral column Part III Flashcards
The Carpometacarpal joints are reinforced by?
Reinforced by palmar and dorsal carpometacarpal ligaments.
All 5 of carpometacarpal are surrounded by?
Common joint capsule
Types of synovial joint, articulation and movement and reinforcement of metacarpophangeal joint.
- Ellipsoid type synovial joints
- Between distal heads of metacarpals and proximal phalanges
- Allow flexion, extension, abduction, adduction, circumduction, and limited rotation * Reinforced by palmar, medial collateral and lateral collateral ligaments
Where do we find deep transverse metacarpal ligaments?
- Connect palmar ligaments to each other
- Absent between thumb and index finger
Types of synovial joint, articulation and movement and reinforcement of interphalangeal joints.
- Hinge type synovial joints
- Between phalanges
- Allow mainly flexion and extension
- Reinforced by palmar, medial collateral and lateral collateral ligaments
The lumbosacral joint
The type of joint, found where, similar to what, Exception and reinforcement of lumbosacral joints.
- Secondary cartilaginous joint
- Between sacrum and L5 vertebrae
- Like those between other vertebrae
- Exception: - Sacrum angled posteriorly on L5 - So, anterior part of intervertebral disc is thicker than posterior part
- Reinforced by iliolumbar and lumbosacral ligaments
The type of synovial, location and reinforcement of sacro-iliac joint.
Plane type synovial joint
* Between L-shaped articular facets on lateral sacrum and similar facets on ilium
* Reinforced by:
- Anterior sacro-iliac ligament
- Interosseous sacro-iliac ligament
- Posterior sacro-iliac ligament
The type of joint, location and reinforcement pubic symphysis joint.
- Secondary cartilaginous joint
- Between pubic bones
- Reinforced by:
- Superior pubic ligament
- Inferior pubic ligament
The type of synovial joint, movement, location and reinforcement of Hip Joint.
- Ball and socket type synovial joint
- Between head of femur and acetabulum of pelvic bone
- Multiaxial joint designed for stability and weight-bearing
- Allows flexion, extension, abduction, adduction, medial and lateral rotation, and circumduction
- Reinforced by:
- Iliofemoral ligament
- Pubofemoral ligament
- Ischiofemoral ligament
- Transverse acetabular ligament
- Round ligament of head of femur
The largest synovial joint in the body.
Knee joint
The articulation of knee joint
- Tibiofemoral joint - Modified Hinge type synovial joint - Between femoral condyles and tibial condyles
- Patellofemoral joint - Plane type synovial joint - Between patella and femur
Movements of knee joints
Allows flexion, extension, medial rotation, and lateral rotation.
The knee joint is surrounded by what?
Single joint capsule
List the intracapsular and extracapsular ligaments of the knee joint.
- Intracapsular ligaments - Anterior cruciate ligament - Posterior cruciate ligament
- Extracapsular ligaments - Patellar ligament - Tibial (medial) collateral ligament - Fibular (lateral) collateral ligament
What is medial and lateral menisci and the location and accommodates it make.
- Fibrocartilaginous C-shaped cartilages
- Between femoral condyles and tibial condyles
- Accommodate changes in shape of articular surfaces during joint movements
What is interosseous membrane of the leg, the location and provide what?
- Fibrocartilaginous C-shaped cartilages
- Between femoral condyles and tibial condyles
- Accommodate changes in shape of articular surfaces during joint movements
Name the 2 apertures of interosseous membrane of leg and the function.
-Superior aperture and inferior aperture
- Allows vessels to pass between leg compartments
The type of synovial joint, movement, location and reinforcement of ankle joint.
Hinge type synovial joint
* Between talus of foot and tibia & fibula of leg
* Mainly allows dorsiflexion and plantarflexion
Reinforced by:
- Medial (Deltoid) ligament
- Anterior and posterior talofibular ligaments
- Calcaneofibular ligament
What does the distal end of tibia and fibula forms when they firmly connect and explain?
Form deep socket for body of talus
- Roof of socket: Inferior surface of distal end of tibia
- Medial side of socket: Medial malleolus of tibia
- Lateral side of socket: Lateral malleolus of fibula
