Joints Flashcards
How can joints be classified?
Structural and Functional
What are the STRUCTURAL classification of joints?
Fibrous
Cartilaginous
Synovial
Which structural classification of joints :
Articulating bones held together by dense irregular connective tissue
Permit little or no movement
Types : sutures and syndesmoses
Fibrous
Which structural classification of joints :
Articulating bones held together by hyaline cartilage or fibrous cartilage
Permit little or no movement
Types : Synchondroses, Symphyses
Cartilaginous
Which structural classification of joints :
Have articular capsule
Characterized by synovial cavity and articular cartilage ;
may contain accessory ligaments, articular discs and bursae
Permit a large range of movement
Synovial
