Question

A home satellite dish receives signals from a satellite, allowing your television to display TV shows. Which part of a neuron is analogous to the satellite dish?

A) cell body
B) dendrites
C) axon
D) varicosities
E) collaterals

Answer 1

The dendrites of a neuron are analogous to a satellite dish as they receive signals from other neurons. The axon then transmits these signals to a target cell.

Step-by-step explanation:

The part of a neuron that is analogous to a home satellite dish, which receives signals from a satellite, is the dendrites. Dendrites are the branching extensions of a neuron that act as input sites, where they receive signals from other neurons. These signals are then transmitted across the soma (cell body), and down the axon, which is the part of the neuron responsible for transmitting an electrical signal to a target cell. Therefore, in the context of the student's original question, the satellite dish, which receives signals, is most closely represented by the dendrites of a neuron.
