A defining characteristic of connective tissue is that cells are separated from one another by large amounts of this.
What is extracellular matrix?
Blast cells, a type of connective tissue cell, do this...
What is build/produce the matrix?
The shapeless background against which cells and collagen fibers are seen under the microscope is called
What ground substance? EC – What is a major type of molecule found in ground substance?
Enclosing and separating, connecting tissues to one another, supporting and moving, insulating... Just to name a few
What are functions of connective tissue?
These are the three main components of connective tissue.
What are protein fibers, ground substance and fluid? EC – Name the three types of protein fibers?
Most epithelial tissue has an area that does not come in contact with other cells, which is called the...
What is the free surface?
Gases and other nutrients must cross this to reach epithelial tissue.
What is the basement membrane?
Protecting underlying structures, permitting passage of substances, secreting and absorbing...
What are the main functions of epithelial tissue?
Protecting against abrasion is a main function of this type of epithelial tissue.
What is stratified squamous?
The structure of columnar cells is such that they more volume than other epithelial cells. This enables them to carry out this function.
What is secretion and/or absorption?
After tissue damage, when new cells look and function just like old cells, this process has occurred
What regeneration?
When a different tissue is formed to replace the original tissue after injury
What is replacement?
These cells continue to divide throughout life
What are labile cells? EC – Give an example
These cells do not divide much if at all after birth.
What are permanent cells? EC – give an example.
If skeletal muscle is damaged, what type of tissue would likely replace the muscle.
What is a transport protein (transports oxygen to bodily tissues)? EC – What type of process would this be?
Redness, heat swelling, pain and disturbance of function.
What are the five major symptoms of inflammation?
Chemical substances associated with inflammation, as a group...
What are mediators of inflammation?
These phagocytic blood cells are responsible for engulfing bacteria after tissue injury and usually die in the process.
What neutrophils?
These organs dilate and become more permeable in order for blood and chemicals to reach damaged tissue.
What are blood vessels?
A fancy name for swelling, this results when water, proteins and other substances flood an injured tissue.
What is edema?
The most varied type of tissue.
What is connective tissue?
This tissue covers internal and external surfaces.
What is epithelial tissue?
Too much of this can lead to disfiguring and debilitating scars.
What is wound contracture?
Serous membranes are composed of this type of tissue.
What is epithelial tissue? EC – can you be more specific?
A delicate connective tissue, consisting of fibroblasts, collagen and capillaries that replaces the clot after injury to a tissue is called
What is granulation tissue?
Final Jeopardy: Tissue Structure vs. Function
What type of epithelial tissue would be found in a heavy smoker, and what effects would this have on tissue function.
Normal: Pseudostratified Columnar Ciliated Epithelium Function: To move mucus (which traps dust/debris) along bronchial passages Smoker: Stratified Squamous Epithelium because of damage to airways from toxins in cigarettes Function: Serves a protective function because of toxins, but does not move mucus, causing coughing and trouble moving foreign materials from surface.
