FIG. 2. The Nerve Supply of the Skin on the Ventral Aspect of the Trunk. 

 The whole of the area shown in the diagram is supplied by branches 

 from the anterior rami (primary divisions) of the spinal nerves. 



G.A, Great auricular nerve; S.C, N. cutaneus colli ; S.CL, Supra-clavicular nerves; 

 ACK, Posterior ; ST, Middle ; CL, anterior ; T.2-I2, Lateral and anterior branches 

 of thoracic nerves; I.H, Ilio-hypogastric nerve; I.I, IHo-inguinal nerve; CIRC, 

 Cutaneous branch of axillary nerve ; L.I.C, Medial cutaneous nerve of the arm (O.T. 

 lesser internal cutaneous nerve); I.H, Intercosto-brachial ; I.C, Medial cutaneous 

 nerve of the forearm (O.T. internal cutaneous); M.S, Cutaneous branch of radial 

 nerve ; E.C, Lateral cutaneous nerves ; G.C, Lumbo-inguinal nerve ; M.C 1 2 , Inter- 

 mediate cutaneous nerves ; I.C 1 , Branch of medial cutaneous nerve ; P, Branches of 

 pudendal nerve ; S.Sc, Branches of posterior cutaneous nerve of the thigh. 



On the other side a schematic representation is given of the areas supplied by the above 

 nerves, the numerals indicating the spinal origin of the branches of distribution to 

 each area.
