Final answer:
An axosomatic synapse occurs between the axon terminals of one neuron and the cell body (soma) of another neuron, which is responsible for integrating incoming signals. Therefore correct option is D
Step-by-step explanation:
An axosomatic synapse occurs between the axon terminals of one neuron and the cell body (soma) of a proximal neuron. During synaptic transmission, a signal is released from the axon terminal and passes through the synapse, reaching the dendrites or soma of the next neuron. The soma in particular is the part of the neuron that integrates the incoming synaptic signals before they are transmitted down the axon. Therefore, the correct answer to the student's question is (d) cell body.
