Histology is the study of tissues at a microscopic level. The French anatomist Xavier Bichat is considered the father of modern histology for introducing the concept of tissue in anatomy in 1801. Histology has several important scopes including use in education to understand cell and tissue behavior, use in medical research to study diseases and treatment effectiveness, and use in medical diagnosis and forensics. A variety of histological techniques exist to prepare, stain, and examine tissue samples under microscopes including maceration, corrosion, immunohistochemistry, radioautography, historadiography, and histochemical methods.
Microtomy, or the preparation of tissue slides, is the foremost technique used in histological studies. This presentation is a brief overview of the technique and the steps involved.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

Chapter: 1
Introduction and scope of histology
By: Bithika Baidya
Content:
• Definitions of histology
• History
• Scopes
• Histological Techniques in brief
2. ❖ Definitions of Histology
‘Histology’ is a Greek word ; ‘histos’ means tissue and ‘logia’ means ‘knowledge’
Thus histology is knowledge of tissue
✓ “The branch of biology which deals with the study of microscopic structure of tissues and
organ with their function”
✓ “Histology is a branch of anatomy which concerns itself with the structural organization of
tissue”
✓ “Histology known as microscopic anatomy or microanatomy is a branch of biology which
studies microscopic anatomy of biological tissue.”
✓ “Histology known as study of form of structure seen under microscope (light, electron,
infrared), also called as microscopic anatomy”
3. ❖ History
✓ French anatomist Xavier Bichat is the ‘father of modern histology’ introduced the concept of tissue in
anatomy in 1801
✓ The term ‘Histology’ was coined to denote ‘study of tissue’ by Karl Mayer in 1819
✓ 1906 Nobel Prize in Physiology or Medicine was awarded to histologist Camillo Golgi and Santiago Ramon
Cajal. (Worked on nerve cells leading to the discovery of structure and function of nervous system)
Xavier Bichat Karl Mayer Camillo Golgi Santiago Cajal
4. ❖ Scope
1. Education: a) Tissue as building block
✓ Histology can help students gain better understanding of cell behaviour making cell biology more
understandable.
✓ Likewise, tissues are building block of everything in the body understanding histology will help students to
predict the co-relation between structure, function and behaviour of an organ
b) Understanding development and evolution
✓ Some organism have no organ and are made entirely of tissues. Similarity with the histology helps students
gain insight into the development of organ and organ system. While evaluating this the student can gain
knowledge on how organ system developed and changed in the course of life.
2. Research:
✓ Many diseases occur at tissue level (Eg: Cancer), for medical professionals research in histology will help
to develop important facts and conclusion in order to treat the diseases.
✓ One can understand the effect of different chemical on tissue via histological research (Toxicity and
carcinogenic)
✓ Research can help you to understand why some treatment work more effectively than other and why
certain lifestyle choice can harm your body over time
5. ❖ Scope:
3. Medical Field:
✓ Histology is used to diagnose disease in human, animals and plants and to analyse the effect and
treatment
✓ A pathologist can identify abnormal cell and tissue conditions and diseases, including cancer and parasitic
infection so that the doctor can give treatment plan.
✓ Histology is used during autopsies and forensic investigation to help understand unexplained death. In
some cases, cause of death is evident from microscopic examination of tissue.
✓ Many medical technology companies and pharmaceutical companies require to test their products need
trained histologist.
4. Other: The variety of fields using histology is ever expanding and has a strong laboratory component.
✓ Histologist working in laboratories include biomedical scientists, medical technicians, histology
technicians (HT), histological technologist (HTL).
✓ Histochemistry: branch of science concerned with the identification and distribution of chemical
constituent in a tissue by means of staining and microscopy.
✓ Archaeologist use histology to study biological material recovered from archaeological sites (Bones and
teeth are most likely to provide data)
✓ Palaeontologists may recover useful material from organism preserved in amber or frozen.
6. ❖ Histological techniques in brief:
✓ Histological technique explains the methodology to obtain animal or plant tissue section, processing,
staining and observing the obtained section under a microscope.
✓ The various steps included in it are obtaining samples, fixation, processing embedding, sectioning and
staining.
7. ❖ Histological techniques in brief:
Structural details of animal tissues can be studied by using the following methods
• Examination of Living cells without chemical treatment
a) Fresh, uncoloured: drop of blood
b) Transparent chamber method: growth of blood vessels and nerves can be directly seen under microscope
c) Tissue culture and organ culture
• Examination of Living cells after chemical treatment
a) Supra vital staining: living cell or tissue can be stained without killing the cell and observed under microscope.
Eg: Janus Green is a supra vital stain used to stain mitochondria
b) Vital staining: dyes without killing the cell. Dye administered via food or injection
• Examination of killed cell:
a) Maceration: tissue is treated with strong and dilute acid and the intercellular substance is removed. Due to the treatment
individual cells, tissue can be isolated.
b) Corrosion: tissue is treated with strong alkali solution so that soft parts dissolves and calcareous part can be maintained
c) Immunohistochemistry: antigen and antibody reaction is carried out in presence of a fluorescent dye.
d) Radio Autography: Radioactive precursor are applied to the tissue for determination of its location in the cell. They are
labelled substance (14C, 3H, 128I , 132I)
e) Historadiography: When X-rays are used for photographing tissue to identify elements, called
Historadiography.
f) Histochemical methods: certain substance in tissue and cells have special affinity for certain chemical substance
or dye.
8. Question
