Cluster of neuron cell bodies within peripheral nervous system are

Options

A. Nuclei
B. Ganglia
C. Laminae
D. Fascicles

Answer

To solve the question "Cluster of neuron cell bodies within peripheral nervous system are," we will follow these steps:

### Step 1: Understand the Terminology
First, we need to understand what is meant by "cluster of neuron cell bodies" and where they are located. In the nervous system, neuron cell bodies are the parts of neurons that contain the nucleus and are responsible for processing information.

### Step 2: Identify the Location
Next, we need to differentiate between the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS consists of the brain and spinal cord, while the PNS includes all the nerves and ganglia outside of the CNS.

### Step 3: Analyze the Options
Now, let's analyze the options provided:
- **Option A: Nuclei** - This term refers to clusters of neuron cell bodies within the CNS, not the PNS.
- **Option B: Ganglia** - This term refers to clusters of neuron cell bodies located in the PNS.
- **Option C: Laminae** - This term typically refers to layers of tissue, not specifically to clusters of neuron cell bodies.
- **Option D: Facils** - This term does not relate to clusters of neuron cell bodies.

### Step 4: Determine the Correct Answer
From the analysis, we can conclude that the correct answer is **Option B: Ganglia**. Ganglia serve as relay centers and intermediates between the CNS and PNS, playing a crucial role in motor control and nerve signal transmission.

### Final Answer
The cluster of neuron cell bodies within the peripheral nervous system are called **Ganglia**.
