✦ Synopsis

The three-dimensional gross morphology of the pituitary gland of the garter snake (Thamnophis sirtalis) is presented. Hormone-producing cells of the pars distalis were localized immunocytochemically. Corticotropes and lactotropes occur in the anterior two-thirds of the gland; corticotropes are especially numerous in the area of the pars distalis nearest the median eminence, and lactotropes are most abundant medially. Somatotropes are restricted to the posterior one-third of the pars distalis. Gonadotropes and thyrotropes are scattered throughout the pars distalis and in favorable sections form a network of cells enclosing clusters of peptide-secreting cells.

A high percentage of the animals also possess accessory parathyroid tissue. Complete parathyroidectomy of the snakes produced severe depression of serum calcium values, tetani

Stress and reproduction are generally thought to work in opposition to one another. This is often manifested as reciprocal relationships between glucocorticoid stress hormones and sex steroid hormones. However, seasonal differences in how animals respond to stressors have been described in extreme e

## Abstract For the first time immunoreactive luteinizing hormone‐releasing hormone (LH‐RH) is demonstrated in both the brain and pituitary gland of a teleost (__Xiphophorus maculatus__) using an immunoperoxidase procedure. It is specifically localized in the perikarya and their axons of the ventra
