Long Bone Structure and Composition

The video tutorial explains the anatomy of a long bone before skeletal maturity, focusing on the epiphyseal plate, epiphysis, diaphysis, and metaphysis. It highlights the differences between bone tissue and cartilage, particularly in the context of the epiphyseal plate and epiphysis. The tutorial also covers how these structures appear in X-rays, emphasizing the translucent nature of the epiphyseal plate due to its cartilage composition.

• Epiphysis

• Epiphyseal plate

• Metaphysis

What is the primary composition of the epiphysis?

• Ligament

• Bone tissue

• Cartilage

• Muscle

Where is the diaphysis located in a long bone?

• Inside

• Between

Which part of the long bone is closest to the epiphyseal plate?
