In order for the players' spines to be cushioned during an impact, the relevant tissue is fibrocartilage.
Fibrocartilage is a type of cartilage that provides support and can absorb shock, making it ideal for structures that undergo pressure and tension, such as intervertebral discs in the spine. This cushioning ability helps protect the spine during collisions or impacts in sports like soccer.
Hyaline cartilage, spongy bone, and hematopoietic stem cells do not provide the same cushioning and shock-absorbing qualities needed during such impacts.
