anterior horn singular

Morphology

anterior + horn

The phrase is directly compositional: 'anterior' means toward the front and 'horn' denotes a projecting part, so together they denote the front projecting section of a structure. This anatomical naming follows regular English composition (and parallels in other languages), so a learner who knows both constituents can infer the basic meaning even without medical detail.

Etymology

Anterior horn comes from the words anterior (meaning 'front') and horn (because a small, horn-shaped part of the spinal cord sits there). That 'horn' contains the nerve cells that tell muscles to move, so anterior horn means the front part of the spinal cord that controls muscle movement.
