Human Biology is a key subject of study in all the subjects related to medicine from radiology to pharmacology. This is the first student dictionary devoted to the subject. In over 6,000 entries, this dictionary covers the topics necessary in understanding how the human body works. There is extensive coverage of the key areas of anatomy, physiology, biochemistry, genetics and immunology, all fields with large specialised vocabularies which are explained and where there are continuing developments in scientific knowledge that are reflected in the entries. Topics such as signs and symptoms of diseases, pathology, medical and surgical treatment, and prescription drugs, are referenced, extending the usefulness of the book. An important feature of the book is the inclusion of a considerable number of detailed key entries written in a style designed to be readily understood by those with no prior knowledge of the topics. Each of these entries gives a detailed introduction to critically important basic topics in human biology, an understanding of which is essential to the mastery of the subject: among these extended entries are Bone, Carbohydrates, Cells, Chemical elements of the body, Circulatory system, Digestive system, Diet, Enzymes, Exercise, Fats, Healing and repair, Immunity, Joints, Muscle, Proteins, Organelles, Reproductive system, Respiratory system, Skin, Skeleton and Urinary system. New students of biology and medicine are likely to find that many of their difficulties arise from nothing more than an inadequate grasp of the basic meanings of important terms. Happily, an understanding of the meaning of a few Greek and Latin roots can cast a wide beam of enlightenment. To assist students and others this dictionary provides all the terminological elements-roots, prefixes, suffixes and combining forms-necessary to resolve such difficulties.

The language of botany from plant structure to genetic modification defined and explained for students of plant sciences and botanical enthusiasts. The dictionary, with over 4,000 entries, covers the many subject areas that make up pure and applied botany. The areas covered include physiology of plants, cell biology, biochemistry, plant pathology, plant anatomy, genetics, evolution and plant ecology as well as important applied topics, such as horticulture, plant breeding, investigative methods, conservation practice and microbiology. To reflect their growing importance in today's world there is extended coverage of biotechnology and genetic engineering, which play such a central role in current developments in plant breeding. The comprehensive coverage of this dictionary is designed to help undergraduates and advanced school students studying biology, botany or plant sciences. It will also be an invaluable resource to naturalists, geographers, horticulturalists and anyone interested in the study and conservation of plants. Following the style of the Collins reference series, the dictionary contains short defining entries, longer explanatory entries and a selection of review entries on such key topics as chloroplasts, DNA and gene, plant groups such as Cyanobacteria or lichen, and investigative equipment, such as the electron microscope.
