It houses crucial organs and structures, including the mouth and reproductive organs, facilitating vital functions such as feeding, movement, and reproduction.

You have injured a disc in your back ( little shock absorbers between your vertebrae ), and it is bulging out at the site of the injury. Take care or it may become herneated or rurtured.
A broad herniation means that at least 25% of the disc is affected. A central herniation means that the herniation is toward the spinal column. A broad central herniation of the disc with impingement on the thecal sac is a herniation in which a large portion of the disc is protruding toward the spinal column and is pressing against the membrane which surrounds the spinal cord.
it means that your disc is slightly bulged. which means it sticks out further than it should between your vertebrates
