This Third Edition of "Medical Cell Biology" focuses on the scientific aspects of cell biology important to medical students, dental students, veterinary students, and prehealth undergraduates. Maintaining a primary focus on eukaryotic cell biology, the text explains general cell biology principles in the context of organ systems and human and animal disease. It contains 60 percent new material! The new topics include: Apoptosis and cell death from a neural perspective; Signal transduction as it relates to normal and abnormal heart function; and, Cell cycle and cell division related to cancer biology. It includes all new clinical cases. It serves as a prep guide to the National Medical Board Exam with a CD-ROM of 200 sample board-style questions (using Exam Master[registered] technology). It focuses on eukaryotic cell biology as it related to human disease, thus making the subject more accessible to pre-med and pre-health students.
