Rods
Receptor
The receptor!
A chemoreceptor can detect changes in hydrogen ion concentration.
bind to receptors in olfactory cilia.
Sensory (afferent) neurons
The eye, specifically rods and cones.
Effector organ is a part of the body that responds to a stimulus and a stimulus is a change in the environment that is detected by a receptor. And is a receptor is a nerve cell that detects a stimulus.
