2)
A) Articular surface of bones in each joint is covered by articular cartilage which is a type of hyaline cartilage. Therefore, the given statement is true.
B) The outer layer of articular cartilage is called as fibrous layer and inner layer is called as synovial layer. Labrum is a fibrocartilaginous ring present in the acetabulum. Therefore, the given statement is false.
C) The inner surface of the articular capsule is surrounded by synovial membrane. Synovial fluid is secreted by the synovial membrane. So, the given statement is true.
D) Articular cartilages are found in synovial joints. Therefore, the given statement is false.
E) Articular cartilage is composed primarily of hyaline cartilage. So, the given statement is true.
