how are joints prevented from hitting against each other?

Question

Hitting joints against each other could be bad for the cartilage,

so let’s say if your jumping on a trampoline, how do the spine vertebral joints prevent from hitting against each other each time you land on your feet?

Answer 1

Vertebrae specifically have discs in between them that are designed to absorb compression forces. These discs contain a gelatinous substance with that helps absorb the forces of impact. The cartilage in other joints is there partially to absorb impact as well. So your joints already have a built-in system to absorb and dissipate impact energy. Over time, these systems break down and may need repair or replacement.
