WebA reflex arc is a neural pathway that controls a reflex.In vertebrates, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord.This allows for faster reflex actions to occur by activating spinal motor neurons without the delay of routing signals through the brain. The brain will receive the input while the reflex is being carried out and … WebOn average a nerve cell sends a signal at about 50 meters per second, which is over 100 miles an hour! This means that when you step on something sharp it does take some time for that signal to go from the nerves in your foot to your brain, although not very much time.

WebNeurotransmitters are how we communicate between one cell and the next. Synapses between neurons are either excitatory or inhibitory – and that all comes down to the neurotransmitter released. Excitatory neurotransmitters cause the signal to propagate - more action potentials are triggered. Inhibitory signals work to cancel the signal.
