4 types of tissues in body
Epithelium (epithelial tissue), connective tissue, muscle tissue, nerve tissue
Covers body surfaces, lines body cavities, forms glands
Epithelium
Underlies or supports the other three basic tissues, both structurally and functionally
Connective Tissue
Made up of contractile cells and is responsible for movement
Muscle Tissue
Receives, transmits, and integrates information from outside and inside the body to control the activities of the body
Nerve Tissue
Germ layers of the embryo
Ectoderm, mesoderm, endoderm
“Cause of the disease”
Etiology
“Sequence of biochemical and molecular events that occur in response to cell injury that give rise to disease”
Pathogenesis
“Structural alterations in cells or tissues that are either characteristic of a disease or diagnostic of an underlying etiology”
Morphological changes
When a tissue biopsy is performed to assist with a diagnosis of a patient
surgical pathology
Gross specimen
ew…. jk unprocessed specimen examined with the bare eye
Microscopic study of normal cells and tissues
Histology
Study of structural, biochemical, and functional changes in cells, tissues, and organs that underlie disease
