The structure of the photoreceptors of the
vervet monkey (Cercopithecus aethiops) has been
investigated by light and electron microscopy. In this
species the photoreceptors can be readily differentiated
and adequately described by the classical terminology of
rods and cones, with rods being the more numerous.
Rods are long, slender cells while cones are shorter and
stouter. Both rods and cones are highly differentiated
cells and consist of an outer segment, a connecting
cilium, an inner segment, a nuclear region and a synaptic
process leading to a synaptic ending. Morphological
differences are noted between rods and cones for the
various regions of these cells.
