Define histology
The study of tissues
What is matrix?
Non living material which surrounds the cells and producing by cells within the matrix
What does the matrix contain? And what are they as well
Protein fibers- collagen, elastic, or reticular fibers
Ground substance- fluids of varying consistency from watery to gel like to rigid
Where is Epithelial tissue and what is its function
Covers the body and organs lining of cavities and blood vessels; all glandular tissue is epithelial Protects Absorbs Filtration Secretion
What are the 3 junctions that make an intercellular attachment
Tight junction
Gap junction
Desmosomes
What is a gland?
One or more cells that secretes a particular product
What are the two major gland types
Endocrine gland and exocrine gland
What is Endocrine gland?
It’s a ductless which secretes into surrounding interstitial fluid which then diffuses into blood for transport
What is Exocrine gland
Empty secretions through ducks it includes what salivary and oil glands; digestive enzymes through pancreatic duct
What are the 3 gland types
Merocrine gland
Apocrine gland
Holocrine gland
What is goblet cell
It’s a unicellular exocrine gland that produces mucus
What are the 2 tissue repairs
Regeneration and fibrosis
Regeneration
A replacement of destroyed tissue by the same kind of cells
Fibrosis
Repairs by dense fibrosis connective tissue (scar tissue)
Visceral
Covers all the internal organs within these closed cavities
Parietal
Lines the body cavities that are closed to the exterior
Pleura
Parietal pleura lines the thoracic cavity
Pericardium
Parietal pericardium lines pericardial cavity
