Lecture 7 Flashcards
What is mobility vs. stability?
strength is inversely proportional to mobility
What are the functional classifications of joints?
synarthrosis, amphiarthrosis, diarthrosis
What is a synarthrosis joint?
immovable
What is an amphiarthrosis joint?
slightly movable
What is a diarthrosis joint?
freely movable
What are the structural classifications of joints?
fibrous, cartilaginous, synovial
What are examples of fibrous joints?
suture, gomphosis, syndesmosis
What kind functional joint is a suture?
synarthrotic
What kind of functional joint is gomphosis?
synarthrotic
What kind of joint is gomphosis?
peg-in-socket
What kind of functional joint is a syndesmosis?
amphiarthrotic
What is a syndesmosis joint?
between two bones that keep them together but allow for some movement
What are examples of a syndesmosis joint?
between the tibia and fibula; between the radius and ulna
What are the cartilaginous joints?
synchondroses, symphyses
What is synchondroses?
bones connected by hyaline cartilage
What kind of functional joint is synchondroses?
synarthrotic
What are examples of synchondroses?
epiphyseal plates, costochondral joints (costal cartilage and ribs)
What are symphyses?
bones connected by fibrocartilage
What kind of functional joint is a symphyses?
amphiarthrotic
What are examples of a symphyses joint?
intervertebral discs and the pubic symphysis
What are synovial joints?
where an articular capsule forms to allow a synovial membrane to hold synovial fluid
What kind of functional joint are synovial joints?
diarthrotic
What is a bursae?
made of synovial membrane that forms a pocket to hold synovial fluid and surrounds the joint
What are articular discs?
oval in shape and transverse the entire joint space
What are menisci?
looks like a kidney bean and doesn’t cover the whole joint space
What are menisci made of?
pads of fibrocartilage
What do muscles and tendons do?
stabilize joints
What are the types of synovial joints?
saddle joint, hinge joint, pivot joint, ball-and-socket joint, condyloid joint, plane joint

inflammation of a bursa because of a blow or friction
What is a sprain?
joint reinforcing ligaments are stretched or torn
What does itis mean?
inflammation
What is a dislocation?
bones forced out of alignment
How is a torn meniscus or articular cartilage repaired?
arthroscopic surgery
What is arthritis?
inflammatory or degenerative disease that damages joints
What are the two types of arthritis?
osteoarthritis and rheumatoid arthritis
What is osteoarthritis?
chronic degenerative condition, wear and tear of articular cartilage
What is rheumatoid arthritis?
autoimmune disease, chronic inflammatory disorder
