What is the lamina propria?
Loose connective tissue beneath membranous epithelia.
Where might elastic connective tissue be found?
In the walls of large arteries
Walls of bronchiole tubes
Special ligaments (eg Ligamentum Nuchae)
What makes the Extracellular Matrix in bone different from that in other tissues?
It is mineralized
What is Elastin assembled from?
Tropoelastin
Fibulin-1
Fibrillins 1 and 2
What are the three types of loose connective tissue?

What can cause shallow breathing in COPD relating to connective tissue?
Elastin breakdown prevents the lungs from retracting fully to prepare for the next inhalation.
What are the fixed cells of areolar connective tissue?
Fibroblasts
Adipocytes
Mesenchymal Cells
What is the most common type of collagen?
Type 1
Besides the structural, what is the function of Extracellular Matrix?
Carries O2, CO2, Nutrients, and Wastes
What are the characteristics of brown fat?
Thermogenic
Abundant in newborns
Greatly reduced in adults
Contains abundant mitochondria
What is the function of Dystroglycans?
