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.

Me waiting for the answers to come into my head with osmosis
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
What do lymph vessels do in joints?
Leave the joint and drains into local lymph node
What are the different shapes of joints? Where are they found?
Pivot joint (fount between C1 and C2 vertebrae)
Hinge joint (like your elbow)
Saddle joint (between trapezium carpal bone and 1st metacarpal)
Plane joint (between tarsal bones)
Condyloid joint (between radius and carpal bones of wrist)
Ball-and socket joint (hip joint)
Where is the atlanto-occipital joint?
Found between C1 and the skull
What is the joint between C1 and C2 called?
Atlantoaxial joint
How do you immediately end an argument?
Say this 👍
Where can you find intervertebral discs?
Between the vertebrae (duh where did you think)
What joint holds the scapula and humerus together?
The scapulohumeral joint (you just put the two words together huh)
Name the carpal joints from proximal to distal side
Radiocarpal, midcarpal, and carpometacarpal
Name the phalangeal joints from proximal to distal
Metacarpophalangeal, proximal interphalangeal, and distal interphalangeal
What is the hip joint called?
Coxofemoral
What is the sacroiliac joint?
It holds the sacral vertebrae to the pelvis
What is adduction?
Moving closer to the body (Putting your feet together)
Describe abduction.
Moving away from the body (Your leg is being abducted by aliens or something idk)
Flexion is….
moving of a joint in the direction it was made to
Extension is….
Stretching of a limb
Me making this
I’m serious help
