Radial Nerve Wrist and Hand

Wrist and hand:

The superficial radial nerve gives rise to branches that spread along the dorsoradial aspect of the wrist and hand and to the thumb and lateral three fingers. 

The deep branch of radial nerve somewhat terminates into a “psuedoganglion” about the fourth extensor retinaculum compartment with the extensor digitorum and extensor indicis. From here it gives branches to the joints of the wrist and hand.
