In a synapse, chemical signal is transmitted fromA) Dendritic end of one neuron to axonal end of another neuronB) Axon to cell body of the same neuronC) Cell body to axonal end of the same neuronD) Axonal end of one neuron to dendritic end of another neuron

The correct answer is:

D) Axonal end of one neuron to dendritic end of another neuron.

Here’s a detailed explanation:

A synapse is the junction between two neurons, where nerve signals are transmitted chemically. This communication typically occurs between the axonal end of one neuron and the dendritic end of another neuron.

Neurotransmitter Release: When an electrical signal (action potential) reaches the axon terminal (end) of the presynaptic neuron, it triggers the release of neurotransmitters into the synaptic cleft (the gap between the two neurons).

Receptor Binding: The neurotransmitters then bind to receptors on the dendritic end of the postsynaptic neuron, which leads to either excitation or inhibition of the postsynaptic neuron, depending on the type of neurotransmitter released.

Signal Transmission: This chemical signaling allows the transmission of the nerve impulse from one neuron to another across the synapse.

Thus, the transmission occurs from the axonal end of one neuron to the dendritic end of the next neuron.
