Which abbreviation refers to the cervical spine?

The abbreviation that refers to the cervical spine is "C-Spine." This term is commonly used in medical settings to specifically denote the region of the spine comprised of the seven cervical vertebrae (C1 to C7), which play a critical role in supporting the head and protecting the spinal cord.

The other options represent different medical terms: "C-Collar" is a device used to immobilize the neck and spine when there is a potential injury; "C-Section" refers to a Cesarean section, which is a surgical procedure for delivering a baby; and "C-Scan" typically designates a method of imaging, such as a CT scan. Understanding these distinctions is important for accurate communication in a medical environment.
