HPCT- (1) INTRO TO GEN PATHOLOGY AND HISTOTECHNIQUES

PATHOLOGY

Study of the structural and functional changes in cells, tissues, and organs that underlie disease.

Pathobiology

pathology is also called ___

Autopsy

systematic examination of a cadaver for study or for determining the cause of death

Necropsy / Post-morten

autopsy also called

Biopsy

examination of cells and tissues from a living organism

Etiology

source of illness

Pathogenesis

development of disease

Morphologic changes

structural alterations

Pathologist

a physician who specializes in interpretation and diagnosis of the changes brought by the disease in our body

• General

• Systemic

2 types of Pathology

General

basic reaction of cells and tissues to abnormal stimuli that underlie all disease

Systemic

specific responses of specialized organs and tissues

• Gross Pathology

• Anatomic Pathology

• Clinical Pathology

  • 
    

Divisions of Pathology

Gross Pathology

recognition of disease based on Macroscopic examination. outer appearance (size, color, consistency)

Anatomic Pathology

study of changes in the function, structure, appearance of organs or tissues, including postmortem examinations and the study of biopsy specimens

• Surgical Patthology

• Autopsy Pathology

• Exfoliative Cytology

  • 
    

3 Branches of Anatomic Pathology

Desquamated cells

fall off layer during exfoliative is called ___

Clinical Pathology

Diagnosis and monitoring of disease through the examination of blood, body fluids, secretions, and tissue biopsy specimens for chemical, morphological, microbiological, and immunological abnormalities.

Clinical Chemistry

division of clinical pathology involving biochemical analysis

Toxicology

analyzing presence of drugs

Hematology

involves assessment of the cellular elements

Blood Banking

a division of clinical pathology that deals with collection, storage, compatibility and saftey of blood and its various components for the purpose of human transfusion

Microbiology

a division of clinical pathology involved in isolation, culture, identification of microorganism

Clinical Immunology and Serology

the discipline in which infectious diseases are diagnosed by detectiong antibodies in serum and other body fluids.

Histotechnology

art of science performed by HISTOTECHNOLOGIST or histotechnician to produce a tissue section of good quality that will enable the pathologist to diagnose the presence or absence of disease.

Histopathologic Technique

involves different procedures that have been adopted fo rthe preparation of materials and tissue for microscopic examination.

Histology

branch of biology that studies the microscopic anatomy of biological tissues

• Muscle tissue

• Nervous tissue

• Connective tissue

• Epithelial tissue

  • 
    

4 Basic typpes of Animal tissue

Muscle Tissue

is a soft tissue that composes muscle in animal bodies and gives rise to muscles’ ability to contract.

Myogenesis

it is formed during embryonic development through a process known as___

Nervous tissue

main tissue component of tthe nervous system

Neural Tissue

nervous tissue also called as __

Neuron

functional unit; transmitting pulses

Neuroglial Cells

supports neurons, sorce of nutrition.
