Functional/Structural Classes of Joints Flashcards
What tissue makes up fibrous joints? Does it have a joint cavity?
Dense regular CT; no
Gomphoses location in the body:
TEETH – SYNARTHROSES
Suture location in the body:
SKULL SUTURES – SYNARTHROSIS
Syndesmosis location in the body:
INTEROSSEOUS MEMBRANES (DENSE REGULAR CT) BETWEEN BONES – AMPHIARTHROSES
What makes up cartilaginous joints? Does it have a joint cavity?
CARTILAGE JOINS BONES; NO JOINT CAVITY
Synchondroses – tissue type and example of location in the body:
HYALINE CARTILAGE – SYNARTHROSES; WITHIN RIB CAGE AND STERNUM
Symphyses – tissue type and example of location in the body:
FIBROCARTILAGE – AMPHIARTHROSES; WITHIN PUBIC SYMPHYSIS AND BODY OF VERTEBRA
What are synovial joints? What are well-known ones?
Diarthroses articulations (yes, ALL); temporomandibular joint, elbow/knee, and glenohumeral (shoulder) joint
Do synovial joints have a joint cavity? What covers it?
Yes. Articular capsule
Articular capsule:
Fibrous layer then synovial membrane (which is AREOLAR CT)
Bones at synovial joints are covered in _____.
Articular (hyaline) cartilage
What is in the articular capsule?
The joint cavity which holds synovial fluid
What is synovial fluid? Texture?
Made of plasma and from synovial membrane. Thick and oily
What purpose does the synovial fluid serve?
Nourishment to chondrocytes, shock absorption, and lubrication
Synarthroses:
NO MOVEMENT
