Which ligament is listed as experiencing tension when the head and neck are lower than the back?

• A. Nuchal
• B. Supraspinous
• C. Interspinous
• D. Ligamentum flavum

Answer: (A)

When the head and neck bend forward relative to the back, the cervical region goes into flexion and the posterior soft tissues above the spine become taut. The nuchal ligament runs from the external occipital protuberance down to the spinous processes of the cervical vertebrae, and its job is to provide passive support and limit further forward bending of the head. In a position where the head and neck are lower than the back, this ligament is stretched, carrying a notable amount of tension to help hold and stabilize the head in that forward-flexed posture. The other ligaments along the spine participate in flexion as well, but they are more general to the entire spine and not specifically the primary structure seen taut with forward head posture. The nuchal ligament’s location and function make it the key structure under tension in this situation.
