Sharp spines in certain animals, like porcupines or certain marine creatures, serve primarily as a defense mechanism. These spines deter predators by causing injury or discomfort if they attempt to attack. Additionally, sharp spines can aid in camouflage or help the animal navigate through its environment. Overall, they play a crucial role in the survival of these species.

The sharp slender process in a human bone is known as a spinous process, also called a neural spine. It is a bony projection that extends off the posterior side of the vertebra, serving as an attachment point for muscles and ligaments.
When feeling a cat's spine, you should be able to feel the individual vertebrae but they should not be protruding or overly prominent. A healthy cat's spine should feel firm and well-covered by muscle and skin. If the spine feels bony or sharp, it could indicate that the cat is underweight or malnourished.
I'm not sure but see a dr !!
The structure you are referring to is likely a "spine" or "spinous process." This sharp, slender projection is found on the vertebrae and serves as an attachment point for muscles and ligaments, facilitating movement and stability in the spine. These processes play a critical role in the overall biomechanics of the skeletal system.
