Question

Discuss how the relationship between photoreceptors and bipolar cells is different from other sensory receptors and adjacent cells.

a) Photoreceptors are directly connected to bipolar cells, unlike other sensory receptors.
b) Photoreceptors have no direct connection to bipolar cells.
c) Photoreceptors have synapses with bipolar cells that enhance signal transmission.
d) Photoreceptors and bipolar cells have a one-to-one connection.

Answer 1

The relationship between photoreceptors and bipolar cells is different from other sensory receptors and adjacent cells. Photoreceptors are directly connected to bipolar cells and have synapses that enhance signal transmission.

Step-by-step explanation:

The relationship between photoreceptors and bipolar cells in the retina is different from other sensory receptors and adjacent cells. Photoreceptors (rods and cones) are directly connected to bipolar cells, unlike other sensory receptors. When stimulated by light energy, the change in membrane potential of the photoreceptors alters the amount of neurotransmitter released onto the bipolar cells, enhancing the transmission of signals.
