What is the fundamental structural unit of a biological nervous system consisting of interconnected processing units? a. Synapse b. Neuron c. Axon d. Dendrite

Break Down the Problem

1. Identify the key terms in the question: "fundamental structural unit," "biological nervous system," and "interconnected processing units."
2. Analyze the options provided: Synapse, Neuron, Axon, Dendrite.

Relevant Concepts

1. Neuron: The basic building block of the nervous system, which transmits information through electrical and chemical signals.
2. Synapse: The junction between two neurons, where neurotransmitters are released.
3. Axon: The part of a neuron that carries impulses away from the cell body.
4. Dendrite: The branching structures of a neuron that receive messages from other neurons.

Analysis and Detail

1. The question asks for the fundamental unit.
2. Among the listed options, the neuron is recognized as the core structural unit that makes up the nervous system and is responsible for the processing and transmitting of information.

Verify and Summarize

• The neuron is distinct from the other options, as it is a complete processing unit on its own. Synapses connect neurons, axons are the communication pathways of individual neurons, and dendrites receive signals, but none of them function as the principal structural unit.

Final Answer

b. Neuron is the fundamental structural unit of a biological nervous system consisting of interconnected processing units.
