Multipolar nerve cells are present in

Options

A. cochlea
B. dorsal root ganglia of spinal cord
C. retina of eye
D. brain

Answer

**Step-by-Step Solution:**

1. **Understanding Multipolar Neurons:**
- Multipolar neurons are characterized by having one axon and multiple dendrites. This structure allows them to receive and integrate a large amount of information from other neurons.

2. **Analyzing the Options:**
- **Option 1: Cochlea**
- The cochlea is a part of the inner ear and primarily contains bipolar neurons, which have one axon and one dendrite.
- **Option 2: Dorsal Root Ganglia of the Spinal Cord**
- The neurons in the dorsal root ganglia are typically pseudounipolar, meaning they have a single process that splits into two branches, one acting as an axon and the other as a dendrite.
- **Option 3: Retina of the Eye**
- The retina contains bipolar neurons, which also have one axon and one dendrite.
- **Option 4: Brain**
- The brain contains multipolar neurons, which are the most common type of neuron in the central nervous system.

3. **Conclusion:**
- Based on the analysis of the options, the correct answer is that multipolar nerve cells are present in the **brain**.

**Final Answer:**
- Multipolar nerve cells are present in the **brain**.
