Primates.

Nonhuman primates demonstrate marked similarities to humans in almost all aspects of their anatomy, endocrinology, and physiology. These similarities underlie the value of these animals for appropriate studies in neurobiology, immunology, pathology, reproductive biology, teratology, neonatology, endocrinology, cardiology, and psychology. Investigations with nonhuman primates has made, and continues to make, significant contributions to biomedical and behavioral research. This review provides an overview of basic and applied studies for which primates are appropriate subjects and a summary of the advantages and problems of using nonhuman primates in research.
