P 73TYPES OF EPIPHYSIS Pressure: Seen at the end of long bones subjected to pressure. E.g. Femur, head of humerus, condyles of tibia and femur. Traction: Formed due to pull of muscles. E.g. Mastoid process, tibial tuberosity, tubercles, trochanters. Atavistic: Functional in lower animals. Degenerated in humans e.g. Coracoid process of scapula, os trigonum of talus Abberant: It is an extra epiphysis. E.g. Proximal end of 1st metacarpal bone.
