myelin
synapse is that junction through which impulse can be transmitted from one neuron to another.
synapse
Nerve messages are called an impulse. Synapses are the space between two axons.
The space through which a nervous impulse is transmitted from one neuron to another is called a synapse. It is a tiny gap between the axon of one neuron and the dendrite of another, where neurotransmitters carry signals across the gap to continue the message.
myelin
No impulse is transmitted. Hence the all or nothing principal.
Chemical diffusion
It is most definitely a synapse.
Neurotransmitters in a neuron allow a nerve impulse to be transmitted from one neuron to another by crossing the synapse and binding to receptors on the receiving neuron. This triggers an electrical or chemical signal to continue the nerve impulse along the neural pathway.
neurons?
The impulse has to cross over a synapse to another neuron or an effector.
A sensory stimulus can generate a neural impulse, as can repeated or multiple inputs of neural signals from other neurons.A neural signal is transmitted from one neuron to anotheracross a synapse via chemicals called neurotransmitters, and a neural impulse is transmitted along an axon of a neuron by either an action potential (in an unmyelinated axon) or by saltatory conduction (in a myelinated axon).
