The firing of action potentials in the visual system are first observed in the:
A)Ganglion cells
B)Bipolar cells
C)Horizontal cells
D)Photoreceptors

Question

Quizplus · Accepted Answer

Ganglion cells are the first cells in the visual system to produce action potentials, which are then transmitted to the brain via their axons in the optic nerve. Bipolar cells and horizontal cells are intermediate cells that help to process and refine visual information before it reaches the ganglion cells. Photoreceptors, such as rods and cones, do not generate action potentials but rather signal changes in light intensity through changes in their membrane potential.
