Ligaments and Tendons Flashcards
The function of ligaments is to
Attach bone to bone
The function of tendons is to
Attach bone to muscle
(T/F) Collagen cross linking is higher in tendons than in ligaments
F - Collagen cross linking is higher in ligaments by quite a bit
(T/F) Ligaments guide and restrict the motion of the joint
T
(T/F) Collagen maturity is a measure of the reducible to non-reducible collagen crosslinks
F - It is the ratio of non-reducible to reducible, and is directly related to the mechanical propreites of bone, tendon and ligament
Material with a higher percentage of non-reducible bonds is
Stiffer
The primary modes of loading in tendons and ligaments is
Tension only
The matrix of tendons and ligaments is laid down by which of the following cell types
Fibroblasts
Cartilage forms in tendons when the tissue is under
Compression (not tension or shear)
Elastin’s ability to recoil after extension is due to which of the following
The random configuration of intermolecular crosslinks
Which regions of the stress-strain curve obtained during mechanical testing of tendons results from the uncrimping of collagen molcules
Toe-In
What are the functions of proteoglycans in tendons and ligaments
To modulate collagen fibril diameter AND to bind extracellular water
How does collagen fibril diameter change in tendons with age
It decreases
