The neck refers to the collection of structures that connect the head to the torso. It is a complex structure of many bones, muscles, nerves, blood vessels, lymphatics, and other connective tissues. The cervical spine is the bony part of the neck. Its primary function is to support the skull while still allowing for movement. It is the most flexible part of the spine. This flexibility allows for large movements to scan our surroundings. Most sensory inputs occur at the head; thus, proper neck movement is vital to survival. The neck also acts as a conduit for the brain to communicate with the rest of the body. Motor and sensory information and nutrients from the body to the head and vice versa must all pass through the neck. The neck is also subject to stress and susceptible to injuries. Given its importance, injuries can sometimes have significant consequences for our functionalities and are even fatal.
