Answer:

3

Explanation:

ganglionic cells

Answer 2

The first cells in the visual pathway that generate action potentials are (1) Photoreceptor cells

Explanation:

1.Photoreceptors are the cells in the retina that respond to light. Their distinguishing feature is the presence of large amounts of tightly packed membrane that contains the photopigment rhodopsin or a related molecule.

2.Two types of photoreceptors reside in the retina: cones and rods. The cones are responsible for daytime vision, while the rods respond under dark conditions. The cones come in three varieties: L, M, and S types (for long, middle, and short wavelength).

3.The optic pathway begins in the retina, which is a complex structure made up of ten different layers. Each layer serves a distinct function.

4.The photoreceptor layers consist of the rods and cones, which generate action potentials with the help of rhodopsin through photosensitive cycles

5.The visual pathway begins with photoreceptors in the retina and ends in the visual cortex of the occipital lobe.
