Spinal nerves


 

 

 

 

 

  • Dorsal (Sensory) root “arises” from dorsal horn joins ventral (motor) root from ventral horn, to form a mixed spinal nerve

  • Spinal nerve divides into dorsal and ventral rami to supply respective muscles and skin


  • Specific region of skin innervated by one cord segment is called a dermatome
