What is the Origin of Cervical Lordosis?

Derived from the Greek "cervix" (neck) and "lordosis" (a bending inward or concave curve). This anatomical term describes a specific sagittal plane orientation of the vertebral column segments C1 through C7.

What is the Mechanism of Cervical Lordosis?

This curve acts as a shock absorber, distributing axial load efficiently across the vertebral bodies and discs. Maintaining this geometry ensures that proprioceptive input from the neck is balanced, reducing undue strain on associated musculature and nervous structures. Postural imbalances, which can be influenced by chronic stress or hormonal shifts, may alter this natural curvature, affecting afferent feedback to the central nervous system.

Cervical Lordosis

Meaning

Cervical Lordosis describes the normal, inward concave curvature of the cervical spine (the neck region), which is essential for maintaining upright head posture and optimal biomechanical alignment. Deviations from the ideal lordotic angle can affect afferent signaling pathways that influence autonomic balance. Proper alignment supports overall structural integrity, which indirectly impacts systemic function.
