A technique to prepare casts of the renal vessels using unsaturated polyester resin solutions is described. The dimensions, morphology and relations of the vessels are very well represented by the casts. The methods is economical and easy to apply and the casts can be used for both teaching and pathologic research.

During the dissection of a male cadaver, 80 years old, it was observed that the right median nerve was formed by the junction of two nerve trunks, one originating from the upper and the other from the middle trunk of the brachial plexus (C5, C6 and C7 neurotomes), with subsequent absence of formation of the lateral cord of the plexus. The place of junction lay at 52 mm from the exit of the C6 and C7 nerves from the spine. The musculocutaneous nerve arised from the median nerve after a 38 mm course of the latter. Despite the absence of nerve fibers from the C8 and T1 neurotomes in the trunk of the median nerve, the distribution of its branches was normal.
