The Vietnamese word "đốt sống" refers to a "vertebra," which is one of the small bones that make up the spine (or backbone) in the human body. The spine is important because it supports the body and protects the spinal cord, which is essential for sending signals between the brain and the rest of the body.
In more advanced discussions, "đốt sống" might be used in terms like: - "Đốt sống cổ" (cervical vertebra) — referring to the vertebrae in the neck. - "Đốt sống lưng" (thoracic/lumbar vertebra) — referring to the vertebrae in the upper or lower back.
While "đốt sống" specifically means "vertebra," it can also refer to the general structure of the spine in discussions about anatomy or health. There are no widely recognized different meanings in other contexts.
