<prompt> Coracoid process is a kind of epiphysis -AtavisticPressureTractionAberrant  <response>: Atavistic epiphysisPhylogenetically an independent bone, which in man becomes fused to another boneExamples:Coracoid process of the scapula Posterior tubercle of talus Os trigonumTYPES OF EPIPHYSES:1. Pressure epiphysis Articular and takes part in weight transmissionExamples: Head of femur Condyles of tibia Lower end of radius2. Traction epiphysisNon articular and does not take part in weight transmissionProvide attachment to a tendon which exerts tractionExamples: Trochanter of femur Tubercles of humerus Mastoid process3. Atavistic epiphysisPhylogenetically an independent bone, which in man becomes fused to another bone Examples:Coracoid process of the scapula Posterior tubercle of talus Os trigonum4.
