He discovered the cellula in a piece of cork during 1665

He verified the organelle and introduction of the term nucleus.

He established the fundamental law of biology

Rudolf Virchow stated "Omnis cellular e cellular" which means "All cells arise in pre-existing cells"

He published the 1st textbook in Histology

Father of Microscopic Anatomy and Embryology

He established the cell theory

He described the nuclear membrane and introduce the term " protoplasm"

He described the nucleus and is known for his invention of the microscope (single-lens microscope)

He observed the cell

Founder of Animal Histology

He created the term "Histology"

He discovered "Tissue"

Histology is derived from the Latin word "Histos= tissue" and "Logos= study"

It deals with the study of microscopic structures of the cells and tissues in plants and animals

Histology is the study of the extracellular matrix of tissues. It also studies the microscopic structures of biological material and the ways in which individual components are functionally related

HISTOLOGY is the diseased or injured tissues while HISTOPATHOLOGY is the normal tissues.

HISTOLOGY is the normal tissues while HISTOPATHOLOGY is the diseased or injured tissues.

The methods of preparation of tissues and cells for microscopic examination are called microtechniques. Microtechniques are the different methods used for the preparation of histological sections.

It is a slice of tissue

It is the spreading of blood film, connective tissue, and bone marrow over glass slide.

Cutting the organ into small pieces or very thin slices (4 - 8µm)

What are the 2 methods for preparing a section?

It is prepared by cutting a specimen imbedded in a paraffin block by a rotary microtome

What is the trimming measures of paraffin section?

Section is prepared by cutting fresh specimen by a freezing microtome

Which of the following is not a process of preparing a sections from organs?

It is the process of assigning the tissue with its corresponding identification or accession number.

It is the process of preserving tissue or materials for histopathologic study and considered as the most critical part of tissue processing using the paraffin method?

It is the process of removing intercellular and extracellular water from the tissue

It is the removal of calcium ion from the tissue and the only tissue processing that can be removed or omitted?

It is the process whereby alcohol is removed from the tissue and replaced by a substance that can dissolve the wax in which tissue is impregnated.

It is the process by which the impregnated tissue is placed into a precisely arranged position in a mold containing medium and allowed to solidify?

It is the removal of a clearing agent.

It is the process whereby tissue are cut into uniformly thin slices or section and usually done by the aid of a microtome

It is the process in which the tissue is artificially colored?

It is the process in which cover slip is applied over the stained tissue section and usually done for the purpose of preservation of tissue slides?

It is the process in which the assigned accession or identification code is permanently attached to the slide and ready for microscopic evaluation.

Microscope came from the Greek word "micron" which is "small" and "skopein" which means "to look at"?

Optical and Mechanical Parts are the general parts of the compound microscope.

Part of the microscope where one peeps or looks to see the specimen under study and usually contains lens that can magnify 10x?

holds the dust shield and the revolving nosepiece

holds the eyepiece or ocular

Holds the objective lens.

Protects the objective lens from dust and dirt

The longest objective; usually marked 100x and used to view structures using oil as a medium.

The shortest objective and usually marked 4x

Used to see the general outline of the specimen usually marked 10x

Used to view structures in a larger perspective usually marked 40x

Holds and secures the slide

It is a part of the microscope where the glass slide is placed.

It rapidly raises or lowers the stage or objective to initially bring the specimen into focus.

It used for more precise focusing.

It moves the stage or slide from left to right and from top to bottom.

Regulates the amount of light entering the stage.

Concentrated the amount of light entering the stage.

Lens nearest to the specimen

Lens nearest to the viewer

The specimen is unstained but the background is dark in shade and used in the diagnosis of syphilis.

The source of light is ultraviolet light and commonly used in immunodiagnostic tests.

The source of light is visible light.

The structures are colored and the background is clear or lighter in shade.

The source of light is an electron beam and it can be a scanning EM or transmission EM. It is mainly used in the study of viruses.

Which of the following is NOT a components of the body

With true nucleus surrounded by a nuclear envelope

Lack of nuclear envelope and the nuclear substance is mixed with the rest of cytoplasm.

Fundamental structural units of living organisms and function in executing all of the activities that the body requires for its survival
