Definition

The dorsal branches of the spinal nerves are the dorsal branches of the spinal nerves.

Anatomy

The posterior ramus further divides into lateral and medial branches, each serving specific functions:

  • Lateral branch: Provides motor innervation to the muscles of the lateral tract, which include:
  • Medial branch: Provides motor innervation to the muscles of the medial tract, which include:
    • Interspinal system
    • Transversospinal system

Both branches also provide sensory innervation to the skin of the dorsal region.
