Morphine has long been known to act on receptors expressed on cells of the central nervous system resulting in pain relief and analgesia.

There is both an analgesia system in the central nervous system and peripheral receptors that decreases the grade in which nociception reaches the higher brain areas.

Further high frequency TENS reduces excitation of central neurons that transmit nociceptive information, reduces release of excitatory neurotransmitters ( glutamate ) and increases the release of inhibitory neurotransmitters ( GABA ) in the spinal cord, and activates muscarinic receptors centrally to produce analgesia ( in effect, temporarily blocking the pain gate ).

In vertebrates, the axons of many neurons are sheathed in myelin, which is formed by either of two types of glial cells: Schwann cells ensheathing peripheral neurons and oligodendrocytes insulating those of the central nervous system.

Any type of focal lesion of the central nervous system ( such as stroke, brain tumour, multiple sclerosis ) will cause the type of ataxia corresponding to the site of the lesion: cerebellar if in the cerebellum, sensory if in the dorsal spinal cord ( and rarely in the thalamus or parietal lobe ), vestibular if in the vestibular system ( including the vestibular areas of the cerebral cortex ).

Exogenous substances that cause ataxia mainly do so because they have a depressant effect on central nervous system function.

A notable opioid for the purpose of relief of diarrhoea is loperamide which is only an agonist of the μ opioid receptors in the large intestine and does not have opioid affects in the central nervous system as it doesn't cross the blood – brain barrier in significant amounts.

Naming the central ray passing through the entrance pupil the axis of the pencil or principal ray, it can be said: the rays of the pencil intersect, not in one point, but in two focal lines, which can be assumed to be at right angles to the principal ray ; of these, one lies in the plane containing the principal ray and the axis of the system, i. e. in the first principal section or meridional section, and the other at right angles to it, i. e. in the second principal section or sagittal section.

The central storage is near a main artery quite easy to reach with large transports on a short crescent swing, with fewer trucks in the residential streets.
