Of these five groups, three are placed anteriorly and they form the first nerve to the corpora cardiaca. The utriculi majores, the largest tubules of the mushroom-shaped sex gland complex of P. americana are lined by a single layer of secretory cells with basal plasmalemmal infoldings and apical microvilli, and enveloped by a thin layer of slow-acting muscle. -    Sense The secretion of accessory glands is mixed with the spermatozoa (or in some insects, it concerned with the formation of spermatophores). abdominal segments.

These glands are paired and white structures and are situated one on either side of crop in the prothoracic region. Utricular /Mushroom shaped gland:- It is a large, whitish accessory reproductive gland. 69. Mushroom gland (utricular gland) consists of two types of tubules, (a) the long slender tubules the utriculi majores of peripheral tubules and (b) short tubules, the utriculi breviores, making up of the major part of the gland. This is called mosaic vision. 0000015986 00000 n Male gonapophysis or phallomeres represent the external genitalia.
