Dendrite toward the cell body, axon away from the cell body.
Synapses. Net flow of charged ions ("impulses") in neuronal cells trigger additional ion flow (ionotropic signaling) or neurotransmitter release (metabotropic signaling) to both neuronal and non-neuronal cell types ("the body") at junctions called synapses.
The axon is the conducting part of the neuron. It conducts the impulse from the cell body to the terminals, where ion channels open in response to the impulse, mediators are activated, neurotransmitter crosses synapse and attaches at the post-synaptic membrane, opening the ion channels there and depolarizing the cell, and propagating the impulse towards another cell body via the post-synaptic cell's axon.
The part of the neuron that carries impulses towards the cell body is called the dendrite.
The dendrite of a neuron usually receives a chemical signal from another neuron, although a cell body (soma), or sometimes even an axon, of another neuron can receive the signal.Synapses which occur between an axon and a dendrite are called axodendritic synapses, while synapses between an axon and a cell body are called axosomatic synapses, and synapses between an axon and an axon are called axoaxonic synapses.
Axon hillock- a pyramidal shaped region where all axons originate fromInitial segment- an area just beyond the axon hillock where all the stimulatory and inhibitory signals coming into the neuron are algebraically summed and it is decided whether or not an action potential should propagate or not.-----The above describes the structure of the axon where the action potential is created.However, the actual nerve impulse (action potential) is generated in a series of steps based on how the ion channels trigger.In this respect the first segment of the nerve impulse is the stimulus, which has to trigger positive ion influx beyond a given threshold.After that stimulus exceeds the threshold, it triggers the opening of ion channels which pump sodium ions into the axon and potassium ions out, thus increasing the net positive charge on the inside of the neuron, depolarizing it and initiating the action potential (the nerve impulse).
The Axon
The axon is responsible for generating and transmitting a nerve impulse. It is a long, slender projection of the neuron that carries the electrical signal away from the cell body towards other neurons or muscles.
There is one way conduction of impulse into the neuron, from dendrites to nerve body to axon.
Neurotransmitters are the chemical messengers that the neurons use. Neurons have certain parts...dendrites which receives information (about some stimulus or from another neuron)...axon is the part of the neuron that conducts/conveys the signal to the synaptic terminals. The synaptic terminals is the part of the neuron that releases the chemical messenger aka the neurotransmitters.

Each nerve impulse begins in the dendrites of a neuron's. the impulse move rapidly toward the neuron's cell body and then down the axon until it reaches the axon tip.a nerve impulse travels along the neuron in the form of electrical and chemical signals.Brain send the message via nerve impulses involving neurons which use the neuro-transmitter Acetylcholine
The axon is the conducting part of the neuron. It conducts the impulse from the cell body to the terminals, where ion channels open in response to the impulse, mediators are activated, neurotransmitter crosses synapse and attaches at the post-synaptic membrane, opening the ion channels there and depolarizing the cell, and propagating the impulse towards another cell body via the post-synaptic cell's axon.
An axon will carry nerve impulses away from the cell body.
The branching fiber that is the first part of the neuron to receive a nervous system impulse is called a dendrite. Dendrites receive signals from other neurons or sensory receptors and transmit these signals to the cell body of the neuron. They play a crucial role in receiving and integrating incoming information in the nervous system.
The dendrites carry impulses to the neuron's cell body. The axon carries impulses away from the cell body.
