| Pineal (Epiphysis) | basement membranes of craniopharyngeal pouch and brain are clearly in contact (O'Rahilly 1973). | slight irregularity in the surface outline of intact head corresponds to future pineal body (O'Rahilly et al. 1982). | pineal body is detectable in roof of diencephalon (Stadium I of Turkewitsch 1933) (O'Rahilly 1968). | cellular migration in an external direction occurs during stages 16 and 17 (Stadium 2 of Turkewitsch 1933) (O'Rahilly 1968). | cellular migration in pineal body forms a distinct "anterior lobe" where follicles appear (Stadium 3 of Turkewitsch 1933) (O'Rahilly 1973 a). | "anterior lobe" shows a characteristic step and wedge appearance (Stadium 4 of Turkewitsch 1933) (O'Rahilly 1968). | pineal body has reached Stadium 5 of Turkewitsch (1933).[1] | ||||
