The review of "Human Embryology" by Bradley M. Patten praises the author's efforts to present the subject in a simple and readable manner, focusing on aspects of human embryology that are particularly relevant to medical students and physicians. The book is commended for its clear and orderly explanation, effective use of examples and analogies, and the omission of unnecessary terminology. The illustrative material, including superb drawings and photomicrographs, is noted as being both discriminatingly selected and generously provided. Additional chapters cover adult aspects of reproduction, implantation, the placenta, twinning, teratology, and age and growth changes. The book is well-printed, formatted, and bound, making it a valuable resource. Minor issues, such as dark photographs, defective labels, and punctuation errors, are mentioned but do not detract from the overall recommendation of the book. The review of "Motor Disorders in Nervous Diseases" by Ernst Herz and Tracy J. Putnam is described as a concise introduction to motor phenomena in neurological examinations. The book provides a detailed description of motor phenomena, including reflexes, from both structural and physiological perspectives.The review of "Human Embryology" by Bradley M.
