The answer is the first one (A): Dendrites.
Explanation for each option:
(A) Dendrites: Correct. Dendrites are the branched extensions of a neuron that receive signals from other neurons. They are specialized to collect information and transmit it toward the cell body (soma).
(B) Axon: Incorrect. The axon is responsible for transmitting information away from the cell body to other neurons, muscles, or glands. It does not receive information.
(C) Soma: Incorrect. The soma, or cell body, contains the nucleus and is responsible for maintaining the cell's health. While it processes information received from dendrites, it is not the primary structure for receiving information.
(D) Myelin: Incorrect. Myelin is a fatty substance that surrounds and insulates axons, facilitating the rapid transmission of electrical signals along the axon. It does not play a role in receiving information.
In summary, dendrites are the part of the neuron that receives information from other neurons.
