Veterinary histology pdf

Grammatical and typographical errors were common, indicating that this text has not been carefully edited. See "other comments" below for specific examples of errors found in the four chapters reviewed.

The four chapters I reviewed did not include any insensitive or offensive text. My qualifications as a reviewer: 27 years teaching histology to medical, pre-medical graduate and undergraduate students.

Extensive familiarity with available histology educational resources, both traditional texts and open, online materials. The goal of proving an open textbook in veterinary histology is a worthy one, given the cost of a veterinary degree, acknowledged by the authors. The present effort, however, falls far short of the quality found in most histology textbooks. The figures that appear often lack captions and rarely have annotation directing the reader to structures mentioned in the text.

In one of the chapters that I reviewed, Male Reproductive System, one figure had errors, including an unintentionally duplicated image, and misleading annotations. Grammatical and typographical errors were common, suggesting that this text has not been carefully edited. When the authors describe, but never illustrate, species differences, the authors focuses exclusively on mammals, with no mention of of non-mammalian classes, including birds and reptiles that represent a significant portion of the animals treated in some practices, and which are not as well represented in other texts.

The materials is "well chunked" into sections that can be quickly mastered--although this process goes to far in some sections that only consist of a single, short paragraph, with no illustrations.

The authors include objectives and questions students should be able to answer at the start of each chapter, which is a positive, but the explanations in this keyword list re sometimes oversimplified, e. Will students who have not studies cell biology know what is meant by "Packaging" in this context?

Intermediate Filaments A broad class of cytoskeletal elements that provide structure and function to a cell. Don't all organelles provide "function? Meiosis A specialized process of cell division that results in the formation of cells with half the chromosome number of the original cell. Should say that these half chromosome cells are sperm and ova for reproduction--gametes Microfilaments Thin cytoskeletal elements that are predominantly involved in the movement of cellular elements.

But microtubles are also involved in the movement of organelles attached to motor proteins. Better to say microtubles subserve both structural and organelle transport functions. Perioxisomes An organelle that breaks down H2O2 and excess fatty acids and is involved in cholesterol biosynthesis Would asking for subscripts be too much? In sum, the chapters that I reviewed, The Cell, Epithelium, Bone which might be better titled "Skeletal Tissues, as it also includes Cartilage , and Male Reproductive System, were well below the standards of existing histology texts, both medical and veterinary.

Most veterinary students would feel severely short-changed by the lack of effective illustrations in this text, and other shortcomings. I recommend that this text be removed from the Open Textbook Library, as I cannot recommend it, or individual chapters as supplements to other materials. Once the authors address these shortcomings, then the book might be re-evaluated for inclusion in the Library. Below I list some of the specific issues and errors in the four chapters I reviewed.

I hope the authors are working on a new edition and choose to address these: I was appalled by the lack of diagrams and micrographs in Chapter 1 the cell. Histology is in essence a visual science--students should be able to recognize subcellular structures in EMs.

Not just for the sake of doing so, but to better understand the relationships between subcellular structures. A major challenge for new students of histology is one of scale--in a micrograph, what are the nuclei, what are the cells, and what are multicellular structures?

By not showing images of cells with some scale information, the authors are wasting an opportunity to help students with this challenge, to say nothing about giving the student an understanding of what organelles look like in electron micrographs, their relative sizes and locations in the cell. From "The Cell Membrane": "Other functions of the membrane are to subdivide the cytoplasm within the cell and increase surface area of the cell.

Later, as above, the authors refer to "the membrane," and sound like they are using "cell membrane" and the bilayer membranes that surround organelles interchangeably.

This sloppy use of terminology will be particularly confusing to the new students of cell biology and histology. In "Nucleus and Nuclear Structures" section, the terms "eukaryote" and "prokaryote" are not defined. They should be defined here or in the keyword sections, where they are absent. Terminology is introduced with no background or context. It will open be just so many new words for the beginner.

For example: "However, a nuclear localization sequence is necessary before transport can occur. The fibrous lamina is the third component of the nuclear envelope. The fibrous lamina is composed of lamin and membrane-associated proteins and is found on the inner surface of the inner nuclear envelope. Similarly will students understand the significance of "hematoxylin and eosin staining" when it used in this section with no prior reference?
