cell as been viewed from the side. The face that is applied to the substrate is ciliated. This face is usually called the right side of the cell because it lies to the right of the mouth. The mouth in this image extends from the anterior (to the right of the picture) to about half way down the ventral (or right) face of the cell. Numerous extrusomes abut onto the membrane of the mouth. There are two rounded macronuclear nodes in the pcture and two small micronuclei (1 o'clock relative to the right-hand nucleus and 10 o'clock relative to the left-hand nucleus).
