In a typical neuron, which structure primarily receives incoming signals from other neurons?

• A. Dendrites
• B. Axon terminals (synaptic knobs)
• C. Myelin sheath
• D. Axon

Answer: (A)

Verified step by step guidance

1. Step 1: Understand the basic structure of a typical neuron, which includes dendrites, a cell body (soma), an axon, myelin sheath, and axon terminals (synaptic knobs).
2. Step 2: Recognize that neurons communicate by receiving, processing, and transmitting signals. The part of the neuron responsible for receiving signals from other neurons is the key focus here.
3. Step 3: Recall that dendrites are branched extensions of the neuron that function primarily to receive incoming signals (neurotransmitters) from the axon terminals of other neurons.
4. Step 4: Differentiate dendrites from other structures: axon terminals send signals, the myelin sheath insulates the axon to speed up signal transmission, and the axon carries signals away from the cell body.
5. Step 5: Conclude that the structure primarily responsible for receiving incoming signals from other neurons is the dendrites.
