Per vehicle mile, motor-cyclists are "35 times" more likely to die in a crash than those traveling by car.
<u>EXPLANATION:</u>
Motor-cyclists usually drive at a very fast speed and also do not follow the traffic norms.
For motor-cyclists, the only protection is a helmet while those traveling in a car are protected from all four sided by the car body and other security equipment installed in cars.
This is one of the main reasons why very few motor-cyclists survive crashes.
Medullary sinuses contain histiocytes (immobile macrophages) and reticular cells. A lymph node contains lymphoid tissue, i.e., a meshwork or fibers called reticulum with white blood cells enmeshed in it. The regions where there are few cells within the meshwork are known as lymph sinus.
