Epifluorescent image, left lateral view. Each of the bilaterally symmetric amphid nerves contains dendrites of 12 amphid neurons and the process of one amphid sheath cell. The amphid nerves travel on the lateral sides of the pharynx to the lips. The axons of the amphid neurons enter the amphid commissures on each side to reach the VNC and NR. DiI-stained animal expressing ver1::GFP marker in amphid sheath cells. Magnification, 400x. (Strain source: R. Roubin, C. Popovici, and S. Shaham.)
