Which of the following illustrates the effect of tendon?
Answers
Answer:
The largest structure in the above schematic is the tendon (shown) or the ligament itselt. The ligament or tendon then is split into smaller entities called fascicles. The fascicle contains the basic fibril of the ligament or tendon, and the fibroblasts, which are the biological cells that produce the ligament or tendon. There is a structural characteristic at this level that plays a significant role in the mechanics of ligaments and tendons: the crimp of the fibril. The crimp is the waviness of the fibril; we will see that this contributes significantly to the nonlinear stress strain relationship for ligaments and tendons and indeed for bascially all soft collagenous tissues.
The above schematic shows the basic common structures for ligaments and tendons. In terms of specific attributes for tendons:

question
Which of the following illustrates the effect of tendon?
..... where's the following options!!???
answer
.....TENDONS
Anatomy:
1. Tendons contain collagen fibrils (Type I)
2. Tendons contain a proteoglycan matrix
3. Tendons contain fibroblasts (biological cells) that are arranged in parallel rows
Basic Functions
1. Tendons carry tensile forces from muscle to bone
2. They carry compressive forces when wrapped around bone like a pulley
Type I Collagen:
1. ~86% of tendon dry weight
2. Glycine (~33%)
3. Proline (~15%)
4. Hydroxyproline (~15%, almost unique to collagen, often used to identify)
Blood Supply:
1. Vessels in perimysium (covering of tendon)
2. Periosteal insertion
3. surrounding tissues
hope it helps you
