ABSTRACT
As most readers of this volume are likely to have only the most superficial knowledge of the development, histological morphology, and endocrine functions of the pineal organ, it was considered appropriate to discuss these aspects in slightly more detail in this chapter than might otherwise have been the case. Similarly, as the clinical management of tumors of this region, although relatively rarely encountered, are becoming of increasing importance, particularly in neurosurgical practice, it is likely that in the relatively near future strains of mice will be produced that have a predisposition toward tumors of this region. As the histological features of these tumors are so diverse, it is important that a great deal more needs to be learned about their early development and the factors that influence the early development of this gland than is presently known (https://www.emedicine.com/med/topic2911.htm).
