Histology notes

Among these, liver and lungs are the most common metastatic sites. These exam notes also represented a defining moment for me as a student, because they proved to me that I was stubborn enough to write a set of exam notes even if it was a complete waste of time.

Bronchioles are lined by simple cuboidal epithelium. For pathological evaluation of tissues, vertical sectioning, cut perpendicular to the surface of the tissue to produce a cross section is the usual method. Because formalin-fixed, paraffin-embedded FFPE tissues may be stored indefinitely at room temperature, and nucleic acids both DNA and RNA may be recovered from them decades after fixation, FFPE tissues are an important resource for historical studies in medicine.

While the vast majority of the students before me had been wasting their time trying to decifer the default book recommended by the anatomy department, I stumbled across a copy of a copy of a book so old that it was literarily written on a typewriter.

It is often used after surgical removal of tumors to allow rapid determination of margin that the tumor has been completely removed.

However, the neuroanatomy exam notes turned out surprisingly competent despite their obscure origins, and they are still the primary study tool for many students here at this university when studying for their neuroanatomy exam. Horizontal also known as transverse or longitudinal sectioning, cut along the long axis of the tissue, is often used in the evaluation of the hair follicles and pilosebaceous units.

Netter, MD over and over again until everything falls into place. Granulomas form in lung tissue. However, this book succeded in every single last aspect where the default book failed, and this elevated the embryology first semester exam notes to a level of clarity and simplicity never seen before here at this medical school.

On the Word

To keep the alveoli clean, amoeboid phagocytic cells crawl over the surface of the alveolar walls and ingest any foreign material that they encounter. Respiratory gas-exchange region of lung The lung consists of functional respiratory units called "air sacs" or alveoli singular, alveoluseach connected via bronchioles and bronchi to the trachea.

This technique has greatly increased the ability to identify categories of cells under a microscope. But wishes rarely coincide with reality. Pre-frozen tissues are placed into molds with the liquid embedding material, usually a water-based glycol, OCT, TBS, Cryogel, or resin, which is then frozen to form hardened blocks.

Other compounds used to color tissue sections include safraninOil Red OCongo redFast green FCFsilver salts, and numerous natural and artificial dyes that usually originated from the development of dyes for the textile industry.

This set of exam notes should therefore ideally have remained in the darkness of my closet never to see the light of day again, but for the sake of completeness they are still being made available here.

For autoradiography on a microscopic level, the slide is typically dipped into liquid nuclear tract emulsion, which dries to form the exposure film. In the lungthe epithelial cells at the ends of all the twigs form "respiratory units", also called alveoli singular, "alveolus".

The qualifiers "male" and "female," because they are based only upon the gonadal histology, frequently contradict the sex of assignment, and thus are very misleading and disturbing for parents and patients.

Its major histological specializations include skeletal reinforcement in the form of incomplete i. However, I still had the ability to illustrate the first 11 questions in the same manner as you have come to expect from me before time ran out.

Many other putative prognostic factors have been reported but the data are still considered preliminary. Stage IV includes patients with parenchymal liver metastases and extra-abdominal metastases. The sclera, also known as the white of the eye, is the opaque, fibrous, protective, outer layer of the human eye containing mainly collagen and some elastic fiber.

In humans, the whole sclera is white, contrasting with the coloured iris, but in other mammals the visible part of the sclera matches the colour of the iris, so the white part does not normally show.
