XORGAN
x-organ: translation
Groups of neurosecretory cells situated in each eyestalk producing a moult-inhibiting hormone [Ingle, 1983].
Site of secretion of molt-inhibiting and other hormones. Located in eyestalks of most decapods or cephalon of sessile-eyed crustaceans. Also referred to as paired frontal organ in Anostraca [McLaughlin, 1980].
(Order Anostraca):
Neurosecretory structure in dorsal region of head; innervated by brain [Stachowitsch, 1992].
(Order Decapoda):
Neurosecretory structure in eyestalk (ocular peduncle). Secretes hormones that inhibit molting and are involved in gonad development and metabolism. In shrimp-like (natantian) decapod one may distinguish medulla terminalis X-organ and sensory pore X-organ [Stachowitsch, 1992].
