sensory neurone --> enters spinal cord --> relay neurone --> brain(is not a reflex action) or motor neurone(if action is reflex)
Efferent nerves carry signals away from the brain to muscles and glands, enabling movement and other bodily functions. A nerve impulse travels in one direction along these nerves, from the central nervous system to the periphery.
A nervous impulse is the relaying of a signal from one part of the body to another in response to stimulus and is only conducted when the neuron has recovered from conducting its last impulse. When the body is under continuous pressure affecting blood circulation and the delivery of oxygen and nutrients the processes are impaired and therefore their ability to conduct nervous impulses is reduced as it takes longer for the impulse to rest before the regeneration of a new nervous impulse
The heart has its own "nervous system" called "purkinje fibers", and so doesn't need the brain to beat ... but the thalamus [oldest part of the brain] does have "override" control via the autonomic nervous system (sympathetic by way of several unnamed nerves and parasympathetic by way of the Vagus nerve.
The Nervous System has two separate control system the sympathetic and the parasympathetic stimulation. Both parts of the system work in opposition to each other. The sympathetic nervous system stimulates the heart, blood vessels, lungs and the metabolic system to prepare for the activity. The parasympathetic system is in control of rest and leisure periods, it also works to conserve energy. As you work out the sympathetic system takes over and act on both the heart and the release of hormones to stimulate the body into workout mode. The nervous system maintains homeostasis by sending signals to the brain and to the rest of the body.
It typically takes about 20-30 minutes for a glass of water to pass through your system and be absorbed by your body.
The nervous system takes in sensory information from the peripheral nervous system. This information is then directed to the central nervous system which then responds with a motor reaction that travels back to the peripheral nervous system.
the neuron consist of the million short dendrites that receive electric impulse to the body cell, also the long axon that takes away the electric impulse away from the cell body and also it contain the myelin sheath that helps in contraction on axon to facilitate the quick transmission of the nerve impulse

Sensory receptors
Nervous is much faster. Impulse transmission happens in mSecs to seconds, hormones are usually agonists of nuclear receptors, and affect gene transcription, which takes hours to days to take full effect.
what two critical symptoms may occur when a patients takes an overdose of central nervous system depressants
Nervous system
The nervous system consist of the central nervous systemand the peripheral nervous system. the central nervous system consists of the brain and spinal cord and the peripheral nervous system is made up of nerves that spread throughout the body, joining all of the body parts to the central nervous system.
An ECG pattern the P-Q interval indicates how long it takes for the cardiac impulse to travel from the SA node through the AV node.

The speed of an impulse traveling through a medium is determined by the medium's properties. If the speed of the impulse is known, we can calculate the time it takes to travel a certain distance using the formula time = distance / speed. However, without knowing the speed of the impulse, we cannot accurately determine the time it will take to travel 10 meters.
