Course Description

Patrick de Permentier
(Course coordinator)
Practical room

The aim of this course is to provide students with a thorough understanding of the microscopic appearance and function of normal structures in the human body. This allows students to integrate this information with other disciplines such as Gross Anatomy, Pathology, and Physiology.

  • The Basic Histology component of the course will concentrate on the microanatomy of the four basic tissues, namely: epithelial tissue, including glandular tissue, connective tissue, muscular tissue, and nervous tissue.
  • The Systematic Histology component of the course will investigate how these basic tissues combine to form organs, which operate together to maintain homeostasis.

General Histology Information

Anatomy is the study of the structure of organs and tissues at the MACROSCOPIC (or gross) level. Histology is the study of organ and tissue structure at the MICROSCOPIC level - it can be considered as microanatomy. Histology provides an insight into how cellular components are structurally and functionally related. It draws its foundations in Biochemistry, Molecular Biology and Physiology as well as Gross Anatomy. Histology provides valuable information on why tissues and organs are shaped as they are. Histology is one of the bases of biomedical sciences. Modern histological techniques allow us to explore and gain understanding of biochemical and physiological processes and how these are changed when structure is changed, as occurs, for instance, in many disease processes. By the end of this course, students should have a thorough understanding of the tissues and systems of the body by microscopic examination and to apply their knowledge to functional states examined in Physiology and diseased states examined in Pathology.

Textbooks

Several books provide adequate coverage of the material in this course. A number of suggestions have been included on the following list. An atlas on its own will usually only cover the practical part of the course, so you will need access to a textbook to cover the theory part of the course.

Histology Drawings

Introduction to Online Support

Images on Practical Support Pages

  • The support class pages contain both labelled and unlabelled histology images.
  • These images are generally not from the virtual slide set.
    • You should use these images to help understand the unlabelled, and examinable, virtual slides used in your practical classes.

Opening Images Separately

  • Histology images on support pages can be opened separately as larger images with more information.
    • To open the image, simply click on the image.
    • Use your browser option to "open image in new tab".
  • Additional information on image page may not always relate directly to histology.
  • To see how this image relates to other topics, look at the bottom of the image information page "File usage".

Cross-Discipline

Some of the practical support pages may contain additional links to related topics in other disciplines in the biomedical sciences. These are listed towards the bottom of each page and are provided to allow potential integration of the histology topic with other disciplines. These are not examinable.

This is also shown when images are opened separately, at the bottom of the image information page is a heading "File usage". This indicates related histology, embryology and anatomy pages that use this image. These pages can be opened by clicking their title in "File usage" section.

Haematoxylin and Eosin
One of the most common staining techniques in pathology and histology. Acronym "H and E" stain. (H&E, HE).


Haematoxylin
  • Stains nuclei blue to dark-blue.
  • Stains the matrix of hyaline cartilage, myxomatous, and mucoid material pale blue.
  • Stains myelin weakly but is not noticeable if combined with eosin stain.
  • combined with Orange G (H & Or. G.) instead of eosin, specifically stains the granules of acidophilic cells of the adenohypophysis (anterior pituitary).
Eosin
  • Stains cytoplasm pink to red; red blood cells are also bright red.
  • Common counterstain to hematoxylin.
  • Stain intensity varies with the formula as well as the fixative.
