Deep branch of radial nerve

Deep branch of radial nerve
Nerve: Deep branch of radial nerve
The suprascapular, axillary, and radial nerves. (Deep branch of radial labeled at right.)
Latin ramus profundus nervi radialis, nervus interosseus dorsalis
Gray's subject #210 944
From radial nerve

The deep branch of the radial nerve winds to the back of the forearm around the lateral side of the radius between the two planes of fibers of the Supinator, and is prolonged downward between the superficial and deep layers of muscles, to the middle of the forearm.

Considerably diminished in size, it descends, as the posterior interosseous nerve.
