The [[Bones - Anatomy & Physiology#Bone Growth|'''physis''']] allows long bones to continue to grow in length after birth and consists of [[Bones - Anatomy & Physiology#Bone Growth|five zones]]. It is is weaker than the surrounding ligaments and bone, and therefore most '''susceptible to injury'''. The physis is weakest at the junction between the proliferative (aka maturation) and hypertrophic zones, and the '''hypertrophic zone''' itself is structurally weak due to the large cell:matrix ratio. | The [[Bones - Anatomy & Physiology#Bone Growth|'''physis''']] allows long bones to continue to grow in length after birth and consists of [[Bones - Anatomy & Physiology#Bone Growth|five zones]].
