  • Title: Accessory parotid lymph nodes and hemal nodes in the temporal fossa in three oxen.
    Author: Constantinescu GM, Brown EM, McClure RC.
    Journal: Cornell Vet; 1988 Apr; 78(2):147-54. PubMed ID: 3371004.
    Abstract:
    No description of accessory parotid lymph nodes in the ox was found in the 25 references consulted. Accessory parotid lymph nodes in two fresh ox heads were found. One of the lymph nodes was located in the temporal fossa on the cornual A., between the artery and the zygomatico- temporal N. and the other one on the route of the lacrimal br. (A) and external ophthalmic V., ventral to the zygomatico-temporal N. The lymph nodes were atypical. The supportive tissue was primarily smooth muscle, no subcapsular or cortical sinuses were seen; no medullary region was evident and the lymphatic tissue was diffuse with no evidence of nodule formation. Two hemal nodes were found in the second and a third fresh ox head obtained from the same source. Both were located on the route of the lacrimal br. of the cornual A. The largest hemal node was normal histologically, with blood-filled sinuses and prominent, active lymphatic nodules. The small hemal node was somewhat atypical in that no trabeculae penetrated the parenchyma and the cortical lymphatic tissue was diffuse with no nodule formation.
