(a) Motor neuron and Sensory neuron
(b) Association neuron and Motor neuron
(c) Sensory neuron and Association neuron
(d) Sensory neuron, Motor neuron, Association neuron
Relevant Equations
Locations of neurons
TL;DR Summary: Location of cell bodies of neurons.

***The cell bodies of which of the following neurons are present in the grey matter of the spinal cord?***

*(a) Motor neuron and Sensory neuron
(b) Association neuron and Motor neuron
(c) Sensory neuron and Association neuron
(d) Sensory neuron, Motor neuron, Association neuron*

This was a test question. (But please don't close the question just reading this line)

I was first confused between A and D somehow. But after a glance at my textbook, I was way more confused than before.
Here are some clicks:

In this picture, they have depicted that the cell bodies of sensory neurons lie in the dorsal root ganglion. Thus, B seems correct.

However, in this picture, they have shown the cell body of sensory neurons (green outline) lies in the grey matter of the spinal cord. Hence D seems correct.


----------

So the final question is where do the cell bodies of the following neurons lie:
1. Sensory -> ______
2. Motor -> ______
3. Association --> _____


----------
I surfed the internet but couldn't find the answer to my confusion about which image is correct. Sorry for English errors.

I've circled out the sensory neuron cell body as depicted in the second image

The cell bodies of most sensory neurons are in peripheral ganglia and therefore not in the grey matter of the spinal cord.
Therefore all the answers including sensory neurons are wrong.

You've circled an interneuron. The sensory neuron to the right is labeled sensory neuron.

Ohkk they have chosen the wrong colour outline. Thanks sir....
