Function: The NECK is an essential part of the body, not only to hold the head upright, but also as an important passage for major nerves and blood vessels that support life and body functions. Located at the uppermost region of the spine, the neck allows for increased range of motion, but is also vulnerable to injury and ailment in relation to its smaller vertebral structure, increased movement capability and complex musculature and ligamentous structures (Moffat, 1999).
