Joints Flashcards
What is arthrology?
the study of joints (and tissues)
What are the structural classifications of joints?
Fibrous, cartilaginous, synovial, and other (?)
What is the joint that holds the maxilla to the mandible called?
Temporomandibular
What are the classifications of joints based on function?
Synarthroses, amphiarthroses, and diarthroses
What are joints that are freely movable called, and where are they found?
Diarthroses, found in the appendicular skeleton
T/F Synarthroses are found in the axial skeleton and are immovable.
True
T/F Amphiarthroses are slightly moveable and are found in the axial skeleton and appendicular skeleton.
False. Amphiarthroses are slightly moveable and are found in the axial skeleton.
What are the characteristics of fibrous synarthroses joints?
They are connected by fibrous tissue and have no joint cavity. Types are suture, gomphosis, and syndesmoses.
Describe suture, gomphosis, and syndesmosis joints in that order.
Suture: A thin layer of dense fibrous CT uniting the bones of the skull. Interlocking edges ass strength and prevent fracture.
Gomphosis joints: Cone shaped pegs in a bony socket.
Syndesmosis joints: There is a greater distance between articulating bones and more fibrous tissue than suture joints.

Limited movement and no joint cavity are characteristics of?
Cartilaginous amphiarthroses joints (Gross long words)
What types of cartilaginous amphiarthroses joints are there?
Synchondroses (found in epiphysial plate, and the joint of sternum and ribs)
Symphyses (found in the pelvis and intervertebral disc)
What is another word for diarthroses joints (the “true” joint)?
Diaarthodial
What is a bursae?
Provides cushion and reduces friction between bones of the joint
T/F Arteries form a network around the joint, capillaries supply nutrition to articular cartilage.
True
