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]
