Adrenocortical and Adrenomedullary Homologs in Eight
Species of Adult and Developing Teleosts: Morphology,
Histology, and Immunohistochemistry

Morphology, histology, and immunohistochemistry of
the adrenocortical and adrenomedullary homologs (adrenal
glands) of the following developing and adult teleosts
were examined: Salmoniformes—Oncorhynchus mykiss
(rainbow trout), Salmo trutta fario (brown trout), Coregonus
lavaretus (white fish); Cyprinodontiformes—Gambusia
affinis (mosquito fish). Perciformes—Dicentrarchus
labrax (sea bass), Sparus aurata (sea bream), Diplodus
sargus (white bream), Oblada melanura (saddled bream).
The anatomical relationships of the gland with the renal
system and venous vessels were also noted. In adults of
all species steroidogenic and catecholaminergic chromaffin
cells were found in the head kidney,which is
pronephric in origin and subsequently transformed
