Question 3

Which of the following best describes the function of synovial fluid in a synovial joint?

Question 7

Which equation correctly represents the relationship between the range of motion ($ROM$) and the structure of a synovial joint?

Accepted Answer

$ROM \propto Joint\ Cavity\ Size$

Question 8

Accepted Answer

Symphysis; fibrocartilage

Question 14

A patient with arthritis has reduced synovial fluid in their knee joint. What is the most likely consequence?
