The optic nerve is made up of the axons of the _____ cells.Multiple choice question.ganglionconebipolarrod

Breakdown the Problem

We need to identify which type of cells contribute their axons to form the optic nerve.

Relevant Concepts

The optic nerve is primarily formed by the axons of ganglion cells in the retina. Understanding the roles of different retinal cells is essential in selecting the correct answer.

Analysis and Detail

1. Ganglion cells: These cells receive visual information from photoreceptors (rods and cones) via bipolar cells and send the information to the brain. Their axons bundle together to form the optic nerve.
2. Cone cells: These are photoreceptors responsible for color vision and are not involved in forming the optic nerve.
3. Bipolar cells: These cells transfer signals from photoreceptors to ganglion cells but do not form the optic nerve themselves.
4. Rod cells: Similar to cone cells, rods are photoreceptors that help in vision under low light but do not form the optic nerve.

Verify and Summarize

Since we established that the optic nerve is formed by the axons of ganglion cells, the answer to the question is clear.

Final Answer

The optic nerve is made up of the axons of the ganglion cells.
