This page will help you obtain accurate head measurements for babies, children and adults. Head sizes vary from person to person, but generally fall into the size categories below. To be sure though, one size does not fit all! To measure your head circumference, wrap a tape measure around the widest part of your head - over your hair, from your forehead, above your ears and around the back, then round to the front again.
Joint between epiphysis and diaphysis with intervening epiphyseal plate of cartilage. 1  Secondary cartilaginous joints: (symphysis): These are also known as fibro-cartilaginous joints. 2  There articular surface is covered by a thin layer of hyaline cartilage and the bones are united by fibro-cartilage.n this type of joints there is a piece of cartilage between the bones which hold the bones together and makes a joint. Cartilaginous joints are further divided into the following subtypes;
(growth in the length of long bones) 1. cartilage on the side of the epiphyseal plate closest to the epiphysis is relatively inactive 2. cartilage abutting the shaft of the bone organizes into a pattern that allows fast, efficient growth 3. cells of the epiphyseal plate proximal to the resting cartilage form three functionally different zones
