What is the medical term for vertebra?

The term "spondyl/o" is indeed the correct medical term for vertebra. In medical terminology, "spondyl/o" is derived from the Greek word "spondylos," which specifically refers to the vertebrae or the spinal column. This prefix is commonly used in various medical terms associated with spinal conditions and disorders, such as spondylitis (inflammation of the vertebrae) and spondylosis (degenerative changes of the spine).

The other options represent different components of medical terminology. "Menisc/o" refers to the meniscus, a crescent-shaped cartilage in the knee. "My/o" pertains to muscle tissue, while "lith/o" indicates stones or calcified deposits within the body, such as gallstones or kidney stones. Thus, when discussing vertebrae, "spondyl/o" is the specific and appropriate term used in the medical field.
