Definition
The rectus capitis posterior minor muscle is a skeletal muscle located on the neck. It belongs to the autochthonous back musculature.
Course
The origin of the rectus capitis posterior minor muscle is the posterior tuberosity of the atlas (1st cervical vertebra). It attaches after a straight course to the linea nuchae inferior of the occipital bone.
Innervation
The innervation of the rectus capitis posterior minor muscle is provided by medial branches of the posterior rami from the spinal nerves of spinal cord segment C1. The dorsal ramus of the first spinal nerve is also known as the suboccipital nerve.
Function
When the rectus capitis posterior minor muscle contracts on one side, the head is slightly tilted and rotated to the same side. When contracted on both sides, the muscle supports the dorsiflexion of the head.
Variety
The rectus capitis posterior minor muscle can either be completely absent or very small on one side.
