Fish bone, besides being simply a term for any bone of a fish, is also a term for bony, rather delicate parts of the skeleton of bony fish, such as ribs and fin rays, but especially the ossification of connective tissue lying transversely inclined backwards to the ribs between the muscle segments and having no contact with the spine.
There are several series of fish bones: Epineuralia, Epicentralia, Epipleuralia and Myorhabdoi.
Fish bones support the core muscles without inhibiting their motility.
In cuisine, fish bones are usually removed and not eaten. Because of their slim, tapered shape they may get caught in the windpipe and cause suffocation.
