Amphids
Nematodes have two amphids which are specialised sensilla situated laterally on the head. These bilaterally symmetrical structures are usually of major importance for identification. Basically there are two kinds, spiral or non-spiral. Usually the non-spiral amphid is a pocket-like structure (Fig. 4A) where the external opening (aperture) is in the form of a transverse slit leading to a cavity (fovea) filled with a gelatinous substance (corpus gelatum). In the spiral amphid the fovea is open and elongated, normally turning ventrally (from the nerve) although in a few cases the amphid may be dorsally wound. When the fovea makes just one turn the amphid may be termed loop-shaped (Fig. 4B) while if several turns are made it is multispiralled (Fig. 4D). Variations on this theme include the transverse amphid (Fig. 4E) and the circular amphid (Fig. 4C), but all are essentially spiral.
