Dendrites of a postsynaptic nerve contain receptors for neurotransmitters released by the presynaptic neuron. These receptors detect and respond to the neurotransmitters by initiating an electrical signal that travels towards the cell body. This signal determines whether the neuron will fire an action potential.

What is the route followed by nerve impulses when one neuron communicates with another?
When one neuron communicates with another, the nerve impulse travels down the axon of the presynaptic neuron, reaches the axon terminal, triggers the release of neurotransmitters into the synaptic cleft. These neurotransmitters then bind to receptors on the postsynaptic neuron's dendrites, initiating a new nerve impulse in the postsynaptic neuron.
What is The purpose of axon?
As far as I understand it, the purpose of the axon is to transmit the electrical impulses (information) of the presynaptic dendrites away from the cell body. The axon therefore acts as a sort of barrier between the postsynaptic dendrites, as it is kind of a one-way street from the cell body to the postsynaptic dendrites. As for why this is necessary, I have no clue. I would assume that if electrical information were to get caught up and stuck somewhere in the cell that it might be damaging to the neuron itself. The purpose of the axon would ultimately be to get the electrical information from the cell body to the postsynaptic dendrites so that chemical production on the neurotransmitter takes place.
Where is information first received by a nerve at?
Information is first received by a nerve at the dendrites, which are the branched extensions of a nerve cell that receive signals from other neurons. The dendrites collect incoming signals and transmit them to the cell body of the neuron for processing.
What part of the nerve are Axons and dendrites?
cell
Cytoplasmic extensions of neurons that act as an antennae for the reception of nerve impulses from what other nerve cells?
Cytoplasmic extensions of neurons that act as an antennae for the reception of nerve impulses from other nerve cells are called dendrites. Dendrites receive signals from other neurons and transmit these signals to the cell body of the neuron.

EPSPs produced by many different presynaptic fibers converging on a single postsynaptic neuron causing summation on the postsynaptic dendrites and cell body best describes?
spatial summation

What process is called a nerve fiber?
Dendrites
What do nerve cells carry messages away from?
From the brain or nerve endings to dendrites
What is the difference between a nerve dendrite and a nerve axon structurally?
The nerve axon is the main nerve from where the dendrites originate.

Cytoplasmic extensions of neurons that act as an antennae for the reception of nerve impulses from other nerve cells are called dendrites. Dendrites receive signals from other neurons and transmit these signals to the cell body of the neuron.
What are the root like structures of a nerve that receive impulses and conduct them to the cell body?
The dendrites are the root-like structures of a nerve that receive electrical impulses The dendrites then conduct the impulse to the cell body. Dendrites are root-like structures of a nerve cell that receive impulses and conduct them to the cell body.
What is the rule of conduction?
· Law of forward conduction: a theory that nerve impulses always travel from postsynaptic membrane of the dendrites to the terminal knob of the axon. The law of forward conduction prevails in nature, but the direction can be reversed under experimental laboratory conditions.
Do the dendrites of a nerve have large number of branches?
No they dont
