EPIPHYSEAL DISC – 1
Notice in the image of a knee joint:
– the epiphyses of the two bones involved in this joint are formed mostly by hyaline cartilage, as the joint was obtained from a very young animal.
– the epiphyseal disk, an extension of the epiphysis, also constituted by cartilage. This disk exists only during the growth stage of long bones, and is then substituted by bone.
– the cartilage meniscus between the two epiphyses.
– the diaphysis of one bone.
– the capsule that covers the joint and helps to hold the bones in correct position.
– striated skeletal muscle surrounding the bone.
