The intercellular spaces of the inner and outer epithelium are connected. The sinuses are covered by two different epithelia: 1) the epithelium in the caoity of the appendage consisting of irregularly shaped cells with processes, the so called (∼ 30 μ high) podocytes, and 2) the epithelium (∼ 40 μ in height) on the surface of the organ, which is composed of two parts: a) a “lacuna”-forming portion directly adjacent to the basement membrane, which is topped by b) a continuous tissue portion with occasional “lacuna”-canals. The blood sinuses are enclosed by a basement membrane which contains collagen equivalents and fine fibrillar elements.
The neurons are often exposed to the blood. It contains free hemocyanin (often aligned in rows), amoebocytes, endothelial cells, and muscle cells which occur mainly in connection with neurons. This organ is dominated by peripherally lobed blood sinuses.
