Cell and Tissue Research Aims and scope Submit manuscript

Summary

By electron microscopy three types of nerve terminals have been identified in adult rabbit pars intermedia (PI). The characteristics of these are described and their development traced. The distribution of nerve terminals and neurons within the PI is documented. In particular the association between types of nerve terminal and the different glandular cells is shown to be precise and selective. Direct innervation of the ACT-type cells in the rabbit PI is described for the first time.

The author is particularly grateful to Dr. J. W. B. Bradfield for help in the preparation of this paper.
