Based on their position and morphology, we identified these structures as the ciliated endings of amphid
Each lip bearing two cephalic papillae and one amphid
. Total length 3.59 [+ or -] 0.65 mm (2.3-4.4) [5.9mm] x 163.3 [+ or -] 22.7.
elegans exhibits both gustatory and olfactory components associated with the amphid
Two cephalic papillae and one small amphid
present on either side at level of base of pseudolabia.
aperture about half of the corresponding body width.
The amphidial sensillum, or amphid
, is an important sensory organ found in all nematodes.
It is believed that nematode amphids
have chemoreceptive organs that could be involved in locating hosts (Steiner, 1925).
Mouth terminal and head containing 6 cephalic papillae, no lip papillae, amphids
reduced, and 6 hypodermal cords at mid-body.
