tissue Flashcards
“histo” -“ meaning
Tissue
- It is the study of the microanatomy of cells, tissues, and organs as seen through a microscope;
- It also examines the correlation between its structure and function.
Histology
The four major tissues in the human body:
- Connective Tissue
- Muscle Tissue
- Epithelial Tissue
- Nervous Tissue
- insulating; helps in binding the organs together and provides support
- It protects against the invasions of pathogens by their phagocytic activity
- Provides shape to the body, conserves body heat and it also stores energy
- Involved in the transportation of water, nutrients, minerals, hormones, gases, wastes, and other substances within the body.
Connective tissue
Three Types of Connective Tissue:
Fluid Connective Tissues
Fibrous Connective Tissues
Skeletal Connective Tissues (bone)
- helps in maintaining posture; helps in the constriction of organs and blood vessels
- Involved in both voluntary and involuntary movements
- Involved in pumping blood and regulating the flow of blood in arteries
- Controls respiration by automatically driving the movement of air both into and out of our body.
Muscle Tissue
Three Types of Muscle Tissue:
Skeletal Muscle
Cardiac Muscle
Visceral or Smooth Muscle
they are typically attached to bones
Skeletal Muscle
found in the heart.
Cardiac Muscle
they are found in the inner walls of organs.
Visceral or Smooth Muscle
- play a major role in sensory reception, excretion, filtration and other metabolic activities.
- Provide mechanical strength and resistance to the underlying cells and tissue.
- It is involved in the movement of materials through the process of filtration, diffusion and secretion.
- Protects the internal organs against the invasions of pathogens, toxins, physical trauma, radiation, etc.
Epithelial tissue
- response to stimuli; Stimulates and transmits information within the body.
- Plays a major role in emotions, memory, and reasoning.
- Maintains stability and creates an awareness of the environment.
- Nervous tissue is involved in controlling and coordinating many metabolic activities.
Nervous Tissue
Contributors in the Development of Histology
Robert Hooke
August Franz Josef Karl Mayer
Sir William Henry Perkin
Marie François Xavier Bichat
-one of the first major milestones in histology came in 1665 with the publication of a small book called ‘Micrographia’
-which is recognized as the first published record of the word ‘cell’.)
Robert Hooke
– a German anatomist and physiologist who coined the term histology and used it first in 1819 in his book entitled “On histology and a new classification of tissues of the human body”
August Franz Josef Karl Mayer
a British chemist and entrepreneur best known for his serendipitous discovery of the first synthetic organic dye, mauveine, made from aniline.
Sir William Henry Perkin
the father of modern histology and pathology.

Selected Branches of Science Related to the Study Histology
Surgical pathology
Immunohistochemistry (IHC)
Stem Cell Biology
Cancer Patho-physiology
Histopathology
Autopsy
is the study of tissues removed from living patients during surgery to help diagnose a disease and determine a treatment plan
Surgical pathology
it involves the process of selectively identifying antigens (proteins) in cells of a tissue section by exploiting the principle of antibodies binding specifically to antigens in biological tissues
Immunohistochemistry (IHC)
Is the study of specific type of stem cells capable of evolving into many different types of specialized cells within the body.
Stem Cell Biology
– it refers to disease processes characterized by uncontrolled growth and spread of cells.
Cancer Patho-physiology
refers to the microscopic examination of tissue to study the manifestations of disease.
Histopathology
an autopsy is a medical procedure involving the examination of a dead body.
Autopsy
Uses of Histology
- In education
- Diagnosis for treatment
- In Forensic Investigations
- In Archaeology
