what is difference between spine and backbone?

Munem Shahriar - 4 years, 1 month ago

A backbone "the series of vertebrae extending from the skull to the pelvis; the spine."

From the link above:

"Insects are often described as “spineless” because they lack a backbone and internal skeleton. It is true that insects lack a backbone but they do have spines.

In insects, spines are cellular outgrowths of the insect exoskeleton that are coated with cuticle. To form a spine, the single layer of epidermal cells that secretes the insect cuticle forms an outgrowth in the shape of a cone. These cells secrete cuticle that hardens over the underlying cells in the shape of a thorn-like spine."
