check isa - not a true gland? There are two types of interrenal cells identified (1) The noradrenaline type, which contain heterogeneous vesicles with electron-dense granules located asymmetrically within the vesicular membrane. (2) The adrenaline type, in which the vesicles are smaller and contain homogenous electron-lucent granules that are separated from the vesicular membrane by a visible -- halo http://dev.biologists.org/content/130/10/2107.full
An epithelial structure consisting of steroid producing cells interposed with chromaffin cells embedded within the head kidney. The interrenal gland is thought to be the equivalent of the mammalian adrenal cortex in zebrafish. Hsu et al. 2003.[TAO]
All craniates have groups of cells homologous to the mammalian adrenocortical and chromaffin tissues, but they are scattered in and near the kidneys in fishes. (...) The cortical and chromaffin tissues come together to form adrenal glands in tetrapods.[well established][VHOG]
