3.2. Topic content.
Nervous and endocrine system controls all activities of body. Primarily, nervous system is divided into two parts:
1) central nervous system;
2) peripheral nervous system.
CENTRAL NERVOUS SYSTEM
It includes brain and spine. It is formed by neurons and supporting cells called neuroglia. The structures of brain and spinal cord are arranged in two layers namely grey matter and white matter. Grey matter is formed by nerve cell bodies and proximal parts of axons and dendrites. White matter contains nerve fibers.
PERIPHERAL NERVOUS SYSTEM
It is formed by neurons and their processes present in all regions of body. This consists of cranial nerves arising from brain and spinal nerves arising from spinal cord. This is again divided into two subgroups:
a) Somatic nervous system and
b) Autonomic nervous system.
1. Somatic Nervous System
It includes nerves supplying skeletal muscles. Somatic nervous system controls movements of body by acting on skeletal muscles.
2. Autonomic Nervous System
It is concerned with regulation of visceral or vegetative functions. So, it is called vegetative or involuntary nervous system with other words. Autonomic nervous system consists of three parts:
a) sympathetic,
b) parasympathetic and
c) metasympathetic.
The idea about the fact that organism having nervous system has possibility to react to external stimuli action by type “buttom-answer” was pronounced by French phylosophist Reneh Decart (XVII-th century).
The term “reflex” was introduced by Irgi Prochazka at the end of XVIII-th century.
The theory of reflectory activity was developed by:
I.M.Sechenov (inhibiting phenomenon discovery; to his point of view, all conscious and unconscious reactions are the reflectory ones).
I.P.Pavlov (science about conditioned reflexes).
Reflex action – 1) is a protective phenomenon which occurs in response to a change inside or outside of the body;
2) responce resulting from passage of a nerve impulse through a reflex arc.
Reflex arc:
It is composed of 5 components i.e.:
Afferent neuron: from receptor to CNS.
Inter Neuron (interneuron) or associative neuron: which lies inside CNS.
Synapse: which is the contact between 2 neurons.
Efferent Neuron: which comes from CNS upto the effector organ.
Efferent Organ: which may be:
skeletal muscle.
smooth muscle.
glands.
Reflex arc types:
1. Simple – without associative link.
Complex – with associative link.
2. Monosynaptic (little amount).
Polysynaptic: tendinous, from skin flexors et al.
3. Somatic (animalous).
Vegetative (autonomic).
Reflex action properties:
1. The law of forward conduction.
2. Localization.
3. Summation:
Temporal summation.
Spatial summation.
4. Facilitation phenomenon.
5. Central fatigue phenomenon.
6. Central block phenomenon.
7. Central delay.
8. Fractionation phenomenon.
9. Irradiation phenomenon.
10. Recruitment and after discharge.
11. Reciprocal innervation.
12. Occlusion.
13. Central inhibiton.
14. Rebound phenomenon (feed-back reaction).
Reflexes classification:
І.According to reflectory arc formation:
Uncondioned or non-conditioned |
Conditioned |
Inborn and transmitted by hereditary to all individuals; they are present at birth. Examples: swallowing, breathing, salivation (sialorrhea or ptyalorhea). |
They are acquired by organism throughout his life. They are absent at birth. |
They are species characteristics. |
Individual ones. |
They have constant reflectory arcs and are closed at spine and brain stem level. |
Reflectory arcs are temporary, they are closed at brain hemispheres level. |
They are practically constant, non-changed. |
Changeable, may appear and disappear. |
They are realized in response to specific (adequate) irritation without any conditions. |
They are realized in response to any irritation percepted by organism. They are formed on the base of unconditioned reflexes. |
They are realized at level of spine, stem and subcortex nuclei. |
They are formed by subcortex but are realized by cortex. |
Biological role: they provide organism’s existance at first moments after birth and then they are the base of conditioned reflexes development. |
Biological role: they encourage to organism adaptation to environmental conditions. |
ІІ.According to reflectory arc components:
Monosynaptic.
Polysynaptic.
ІІІ.According to main arc neurons localization:

ІV.According to receptors character, the irritation of which causes given reflex:
