excretory canal

Four processes (canals) of the excretory canal cell each contain a central collecting lumen which feeds to a central lumenal canal in the cell body; the central canal forms a specialized membrane to release fluids into the excretory duct. These five canals form a continuous H-shaped channel which extends almost the full length of the body, generally in contact with the lateral hypodermis and the pseudocoelom.

cuticle

a rigid external coating which is secreted by the hypodermis, seam and some transitional epithelial cells which covers the outer body, the major openings into the body cavity from the exterior, and two large sensory bristles, the male spicules. The cuticle of the spicules, the hook, and of some portions of the spicule channels is especially rigid and is probably sclerotized. Similar sclerotic features are occasionally noted in the ventral surface of the male tail fan.

secondary spermatocyte

rectal epithelial cell

These cells include: B, F, Y, U, K' and K. All rectal epithelial cells contain secretory membrane stacks along this region facing the lumenal cuticle and produce some portion of the cuticular lining of the rectum. These are interfacial cells that connect the alimentary system to the main body syncytium.

Neuron class of six motoneurons, with cell bodies in the ventral cord, which innervate dorsal muscles. Each cell has a short, posteriorly directed and a longer, anteriorly directed process emanating from its cell body. The anterior process has a branch, which leaves the ventral cord as a commissure and runs round to the dorsal cord.

Small linear ridges running along the lateral lines of the cuticle, lengthwise along the body; these thickenings lie in register with the seam cells which likely produce them and are present in the cuticle of the L1, dauer and adult stages, but not in other larval stages. The alae are suspected to provide better traction when the animal generates a bodywave. Since the animal usually lies on its side, the alae are in perfect position to catch against the substrate.
