Final answer:
To match neuron parts with their descriptions, we should understand their structures and functions. The correct matches follow as dendrites are branched structures (c), chromatophilic substance corresponds to rough endoplasmic reticulum (e), axons conduct impulses (d), the cell body is where axons and dendrites extend (b), and neurofilaments are fine threads in an axon (a). The correct option is A.
Step-by-step explanation:
To match the part of a neuron with its description, we need to understand the structure and function of a neuron. A neuron is the basic unit of the nervous system and is responsible for transmitting information throughout the body. The three main parts of a neuron include the dendrites, the axon, and the cell body (soma).
Dendrites are highly branched structures that receive signals from other neurons and conduct these signals to the cell body. The axon is a long, slender projection that transmits signals away from the cell body to other neurons or to muscles or glands. The cell body is the metabolic center of the neuron and contains the nucleus and most organelles.
Let's now match the neuron structures with their descriptions:
- Dendrites (1) - Highly branched, multiple processes that may have spines (c).
- Chromatophilic substance (2) - Rough endoplasmic reticulum (e).
- Axon (3) - Conducts impulses (d).
- Cell body (4) - Part of neuron from which an axon and dendrites extend (b).
- Neurofilaments (5) - Fine threads in an axon (a).
Based on these associations, the correct match using the provided options would be:
A) 1-c, 2-e, 3-d, 4-b, 5-a
Hence, the correct option is A.
