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 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;
In adult bones, there is a thin line of bony tissue spanning the epiphysis that looks a bit different from the rest of the bone in that area. The epiphyseal line is a remnant of the epiphyseal plate (a flat plate of hyaline cartilage) seen in a young, growing bone & causes the lengthwise growth of a long bone.n adult bones, there is a thin line of bony tissue spanning the epiphysis that looks a bit different from the rest of the bone in that area.
