Question

The multiple thin, branched structures on a neuron whose main function is to receive incoming signals are the

A. cell bodies.

B. axons.

C. dendrites.

D. somata.

E. None of the answers are correct.

Answer 1

The correct answer is C. dendrites, which are the branched structures on a neuron that receive incoming signals from other cells and relay them to the neuron's cell body (soma).

Step-by-step explanation:

The multiple thin, branched structures on a neuron that are primarily responsible for receiving incoming signals are the dendrites. Unlike axons, which typically carry signals away from the neuron's cell body, dendrites function as the main receivers of signals from other neurons. Dendrites may form a complex 'tree' with many branches, increasing the surface area for making synaptic connections with other neuronal cells.

The correct answer to the student's question is C. dendrites. They are crucial for neuron communication, as each dendrite can receive nerve impulses from other neurons and carry these signals to the neuron's soma, or cell body, for integration. Dendritic spines, which are small protrusions found on dendrites, further increase the neuron's capacity to form connections with other neurons.
