Tegumental glands of Hutchinsoniella macracantha (Cephalocarida)

Elofsson, Rolf LU and Hessler, Robert R (1998) In Journal of Crustacean Biology 18. p.42-56
Abstract
Three types of tegumental glands of Hutchinsoniella macracantha body, limb, and caudal, are described for the first time. Previously described salivary and cement glands also belong to this category. All have the same fundamental construction. They consist of 1 or 2 secretory cells opening into a short cuticular channel ending in a pore. The channel is Formed by a sheath or canal cell and an intermediate cell. The intermediate cell has an actin-like filament bundle encircling the duct. If is a type of tricellular tegumental gland common in crustaceans.

The secretory cells can be very large, the caudal gland in the cerci being 0.5-0.6 mm in length. They are, at least distally, completely filled with secretory granules. Some... (More)
Three types of tegumental glands of Hutchinsoniella macracantha body, limb, and caudal, are described for the first time. Previously described salivary and cement glands also belong to this category.

The channel is Formed by a sheath or canal cell and an intermediate cell. The intermediate cell has an actin-like filament bundle encircling the duct. If is a type of tricellular tegumental gland common in crustaceans.

The secretory cells can be very large, the caudal gland in the cerci being 0.5-0.6 mm in length. They are, at least distally, completely filled with secretory granules. Some contain enormous Golgi-like bodies. The secretory cells vary in cytological details and granular secretion, both within a pair and depending on body position. It is concluded that a common gross morphology of the tegumental glands of Hutchinsoniella houses different functions. (Less)
