MICROANATOMY

Detailed explanation-1: -On the epiphyseal side of the epiphyseal plate, cartilage is formed. All that remains of the epiphyseal plate is the epiphyseal line . As a bone matures, the epiphyseal plate progresses to an epiphyseal line. (b) Epiphyseal lines are the remnants of epiphyseal plates in a mature bone.

Detailed explanation-2: -The epiphyseal line is a remnant of an area that contained hyaline cartilage that grew during childhood to lengthen the bone. All of the bones in the arms and legs, except the patella, and bones of the wrist, and ankle, are long bones.

Detailed explanation-3: -In the late pubertal patient, growth plate remnants were found at the site where in less mature bones the epiphyseal plate is located. These remnants were small and surrounded by dense cortical-like bone. Chondrocytes within these growth plate remnants were disorganized and no columns could be found.

Detailed explanation-4: -(b) Epiphyseal lines are the remnants of epiphyseal plates in a mature bone.

Detailed explanation-5: -As an individual reaches the end of the overall growth period, caused by increased concentrations of sex steroid hormones during puberty, the cartilage of the epiphyseal plate diminishes and is finally replaced by bone to form the epiphyseal line.
