All of following are examples of traction epiphysis except:-
Epiphysis is the pa of bone which ossifies from the secondary centre. It may be of three basic types; 1) Pressure epiphysis:- it transmits the body weight and protects the epiphyseal cailage. E.g. heads of femur and humerus, condyles of femur and tibia. 2) Traction epiphysis:- it is produced by the pull of some muscles. E.g. trochanters of femur and tubercles of humerus. 3) Atavistic epiphysis:- it is phylogenitically an independent bone and is attached secondarily on a host bone to receive nutrition. E.g. coracoids process of scapula and posterior tubercle of talus or os trigonum.
Tubercles of humerus.
Posterior tubercle of talus.
Trochanters of femur.
None of above.
