Nematode anatomy

A cuticle (), or cuticula, is any of a variety of tough but flexible, non-mineral outer coverings of an organism, or parts of an organism, that provide protection. Various types of "cuticle" are non-homologous, differing in their origin, structure, function, and chemical composition.

Amphids (Greek: amphi, around, double) are innervated invaginations of cuticle in nematodes. They are usually found in the anterior (head) region of the animal, at the base of the lips. Amphids are the principal olfactosensory organs of nematodes. Each amphid in C. elegans is made up of 12 sensory neurons with ciliated dendrites. The neurons have multiple shapes, such as single cilium, double cilia, wing-like cilia, and dendrites embedded in the sheath-cell with villa. Other nematodes, such as Bursaphelenchus xylophilus, have different configurations of specific types of neurons, with B. xylop

Individual stichocytes contain networks of intracellular canaliculi and open into the esophageal lumen by a narrow duct process, likely with secretory functions. Function as a storage organ has al
