The objectives were to contribute with systematic data about the position of the thymus gland in relation with the skeleton, its topographical and morphometrics parameters and the type, the origin, the number, and the organization of thymic vessels associated in the organ vascularization. It had been used 26 caprins foetus of Saanen breed for macroscopic study that had had their arteries vessels injected with a latex Neoprene 450 solution and 4 foetus for microscopic study of the thymic arteries vascular wall structure. The thoracic and cervical thymic parts showed an own vascularization by direct and indirect branches with the thymic vessels showing a predominant elastic fiber structure on the middle layer without differences between the types.
