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;
There are four types of epiphysis: 1  Pressure epiphysis: The region of the long bone that forms the joint is a pressure epiphysis (e.g. the head of the femur, part of the hip joint complex). Another example of a pressure epiphysis is the head of the humerus which is part of the shoulder complex. 2  Traction epiphysis: The regions of the long bone which are non-articular, i.e. not involved in joint formation. 3  Unlike pressure epiphyses, these regions do not assist in weight transmission.
