Bony jawless fish, such as lampreys and hagfish, and cartilaginous fish, like sharks and rays, share similarities in being part of the broader category of jawless vertebrates. Both groups possess a primitive body structure and lack true jaws, relying on suction or other means to feed. Additionally, they both have a cartilaginous skeleton to varying degrees, contributing to their flexibility and adaptability in aquatic environments. Despite these similarities, they belong to different evolutionary lineages with distinct characteristics.
hyaline cartilage
osteoblast
Humans do not have the same amount of cartilage in their bodies for their entire lives. Rather, as people age, the amount of cartilage in their body decreases. This can cause older people to experience joint pain.
A bony line of articulating vertebrates - the same as in humans.
Yes, but often imperfectly and it takes a great deal of time. Cartilage tends to have a very poor blood supply, so it takes a long time for the cells to gather enough nutrients to build more matrix and repair the damage. If the damage was too severe, the cartilage will not have time to repair the damage before bony changes take over and prevent a return to normal function.
No, they are bony fishes.
hyaline cartilage
No sharks are not 'bony'. The skeletal makeup of sharks is cartilage. Although cartilage is dense and can be bone-like it is significantly less dense than bone.
bony; the only cartilaginous fish currently in existence are sharks, skates, and rays.
Another word for the noun cartilage is ossein. Another synonym for cartilage is osseous matter. A related term for cartilage is bony process.
No, because a shark is not a bony fish as it's skeletal structure is made of cartilage.
Osteochondroma is a benign growth of bone and cartilage.

yes. bony fish (class osteichthyes) have a vertebral column and a bony skeleton. cartilaginous fish (class chondrichthyes) have a vertebral column as well but their skeleton is made up of cartilage.
osteoblast
For the most part, they do not have bones. They have cartilage.
