Nerve impulse diagram

Neurotransmitter binds to receptor proteins on post-synaptic membrane 7. All the nerve fibres carry information in the form of nerve impulse. Nerve impulse is the sum total of physical and chemical disturbances created by a stimulus (electrical, chemical or mechanical) in a neuron or nerve fibre which result in the movement of a wave along the nerve fibre. The inset diagram shows in detail the structures and processes occurring at a single axon terminal and synapse. At a chemical synapse, both the presynaptic and postsynaptic areas of the cells are full of the molecular machinery that is involved in the transmission of nerve impulses.

In nerve and muscle cells the membranes are electrically excitable, which means they can change their membrane potential, and this is the basis of the nerve impulse. The sodium and potassium channels in these cells are voltage-gated , which means that they can open and close depending on the voltage across the membrane.

Here’s the same diagram we examined at the start of this tutorial (before we knew how action potentials worked). STEP 5: TRANSMISSION ACROSS THE SYNAPSE - Neurons do not touch, the axon terminals stop before reaching the dendrites of the next neuron. - The gap between these two neurons is known as synapse - Impulses are carried across a synapses by neurotransmitters (chemical messengers).

A neuron can receive input from other neurons via a chemical called a neurotransmitter. If this input is strong enough, the neuron will pass the signal to downstream neurons. The nerve impulse (or information) is carried from the first neuron, called presynaptic neuron, and received by another neuron, called the postsynaptic neuron. The presynaptic and the postsynaptic neuron may or may not be separated by a gap which is known as the synaptic cleft. Nerve impulse can define as a signal driven by either electrical, chemical or mechanical stimulus onward the segment of an axon filament.
