Harderian Glands

The Harderian glands, located within the orbital cavities of amphibia, reptiles, birds and most mammals, are perhaps one of the last discrete tissues for which we connot yet define a normal physiological role or regulation. The book brings together all known information on the Harderian glands. It covers comparative anatomy at several levels, the concentra- tions and regulation of indole and catecholamines, porph- yrins, peptides and lipids, and the interactions of the Har- derian glands with the thyroid and pineal glands. One chap- ter is devoted to the avian Harderian glands and their role in the immune response, and another to the glands in amphi- bia and reptiles. Containing a master bibliographic compila- tion of all known literature on the Harderian glands the book represents a valuable reference source which offers new or established investigators a ready and convenient base of information.
