| Recently, in 1893, Kupffer has also put forward the view that the hypophysial opening is the palostoma. |
| Gametogenesis appeared to be unaffected by hypophysectomy suggesting that the hagfish gonad was independent of hypophysial gonadotropic control. |
| Beard therefore called this opening of the hypophysial tube the old mouth, or palostoma. |
| These neurons project axons to the median eminence where they secrete CRH into the hypophysial portal blood. |
