18 Questions
What is a key objective of studying tendons and ligaments in the context of biomechanics and surgery?
Describing the mechanical behavior of tendons and ligaments in response to tensile loads
What is one of the components that make up tendons?
Collagen fibers
How does stress deprivation affect tendons and ligaments?
Reduces their flexibility
Which factor does NOT influence the mechanical behavior of tendons and ligaments?
Emotional factors
In tendon healing, what is an important aspect to describe about the mechanical properties?
Increased stiffness
What is one function of tendons in the body?
Attaching muscles to bones
What is the primary function of the musculotendinous unit?
To transmit tensile forces from the muscle to the bone
What is the main difference in composition between tendons and ligaments?
Tendons transmit tensile forces from muscle to bone, while ligaments limit joint motion.
What is the function of the tendon synovial sheath?
To provide a closed duct around the tendon, allowing it to glide on bone surfaces.
What is the difference in the general biomechanical behavior between tendons and ligaments?
Tendons can withstand unidirectional tensile loads, while ligaments can resist high tensile loads in one direction and smaller tensile loads in other directions.
What is the name of the junction between the tendon and the muscle?
Myotendinous junction (MTJ)
What is the name of the junction between the tendon and the bone?
Osteotendinous junction (OTJ)
What is the primary function of the synovial fluid in the synovial sheath surrounding tendons?
To provide lubrication and facilitate smooth gliding of the tendons
What is the purpose of the annular pulleys surrounding tendons?
To provide a fulcrum and add mechanical advantage to flexion
What is the primary function of the paratenon surrounding some tendons?
To reduce friction and permit free movement of the tendon
What is the primary component of the paratenon surrounding some tendons?
Loose fibrillar tissue (type I and III collagen)
What is the primary function of the epitenon surrounding tendons?
To provide a fibrillar network of collagen around the tendon
What happens to the epitenon fibers when the tendon is stretched?
They reorient themselves to a smaller angle with the tendon axis
This quiz covers the structure, metabolism, biomechanics, function, and development of tendons. Topics include construction of tendons, collagen fibers, cells of tendons, mechanical properties, and more. Optional readings focus on the functional outcome of acute Achilles tendon rupture with and without operative treatment.
