Joint Classifications by Tissue Type Flashcards
Classification by type of tissue in articulation
- Fibrous
- Cartilaginous
- Synovial
Joint classification by type of tissue with no/limited movement
Fibrous
Joint classification by type of tissue where bones are connected by connective tissue
Fibrous
Joint classification by type of tissue which are slightly moveable
Cartilaginous
Joint classification by type of tissue where bones are connected by cartilage
Cartilaginous
Joint classification by type of tissue which are highly moveable
Synovial
Joint classification by type of tissue where bones are lined with cartilage, surrounded by cavitated CT filled with synovial fluid
Synovial
Suture tissue type
Fibrous
Where are sutures confined to?
Cranium
What are the bones of the sutures connected by
Collagenous sutural ligaments (sharpey’s fibers)
Function of sutures
Shock absorption
Gomphosis tissue type
Fibrous
What are the bones of gomphosis joints connected by?
Cartilaginous periodontal ligament-dental cementum
Function of gomphosis
Anchors tooth in socket
Syndesmosis tissue type
Fibrous
What are the bones of syndesmosis joints connected by?
Cartilaginous interosseous ligament
Examples of syndesmoses
- Radioulnar interosseus ligaments
- Tibiofibular interosseus ligaments
- Anterior/posterior longitudinal ligaments of the spine
- Ligamentum flavum
Syndesmoses function
Dynamic stabilization, resisting forces that separates the bones
Synchondrosis tissue type
Cartilaginous
What are the bones of synchondrosis joints connected by?
Hyaline growth cartilage
What kind of cartilaginous joint is synchondrosis?
Primary
Examples of synchondrosis
- Epiphyseal growth plates
- Basisphenoid synchondrosis
Symphysis tissue type
Cartilaginous
What are the bones of symphysis connected by?
Hyaline cartilage-fibrocartilaginous disc-hyaline cartilage
What kind of cartilaginous joint is symphysis?
Secondary
To where are symphyses restricted?
Axillary skeleton, medial
Symphyses function
- Stability
- Resist forces at weight bearing joints
Locations of symphyses
- Manubriosternal
- Xiphisternal
- Intervertebral disc
- Pubic symphysis
- Mandibular symphysis
Symphyses that undergo synostosis
- Manubriosternal
- Xiphisternal
- Mandibular symphysis
What are the bones of diarthroses connected by?
Hyaline articular cartilage-cavitated CT-hyaline articular cartilage
Fibrous joint capsule filled with synovial fluid
Cavitated connective tissue
Most diarthroses are what type of joints?
Synovial
Types of ligaments in and around the synovial joints
- Extrinsic
- Intrinsic
- Intracapsular
Ligament outside of the fibrous joint capsule
Extrinsic ligament
Ligament within or on the surface of the fibrous joint capsule
Intrinsic ligament
Ligament inside of the synovial cavity
Intracapsular ligament
Example of extrinsic ligaments
Lateral collateral ligament (LCL) of the knee
Example of intrinsic ligaments
Ischiofemoral/pubofemoral ligaments of the hip
Example of intracapsular ligaments
- Ligamentum teres of the hip
- ACL/PCL of the knee
Area of adipose tissue within the joint capsule to cushion the articulation
Fad pad
Fibrocartilaginous disc tissue type
Synovial
In synovial joints, what are fibrocartilaginous discs called?
Menisci
Where menisci are found
- Knee
- Sternoclavicular joint
