Question

Quizplus · Accepted Answer

The elbow joint is a diarthrotic joint, also known as a synovial joint. This means it is a freely moving joint that is surrounded by a joint capsule containing synovial fluid. The elbow joint allows for flexion and extension, as well as some rotation. It is not cartilaginous, as this type of joint is made up of cartilage rather than bone. It is not pivot, as a pivot joint is a type of synovial joint that only allows for rotation. It is not biaxial, as this type of joint allows for movement in two distinct directions, and the elbow joint primarily allows for movement in only one plane.
