New Observations on Lymph Gland (LM1) and Thymus Activity in Larval Bullfrogs, Rana Catesbeiana
The lymphoid and myeloid (chiefly, bone marrow) systems are concerned principally with the immune response capacity in most vertebrates. With the exception of birds and certain mammals, the thymus acts alone as a major organ and is necessary for the maturation and maintenance of immune competence. I shall restrict my presentation to a review of new information on the role of lymph gland and thymus in larval bullfrogs. I will not consider the thymus or other organs of the lymphomyeloid complex in other larval anurans (1,2,3,4).
