The small front head flexor
Rectus capitis anterior · musculus rectus capitis anterior
A tiny muscle between the atlas and the skull that helps nod the head.
What it does
This short, flat muscle runs from the front of the atlas to the base of the skull. It bends the head forward at the top joint of the neck and steadies that joint.
Surprising fact
It is one of the smallest muscles in the neck, and it works across just a single joint, between the skull and the first vertebra.
Why it matters
Small deep muscles like this one fine-tune head position, helping you keep your gaze steady while you walk.
