Adaptation-trophic function - the influence of the sympathetic nerves in exchange intensity and strength of contractions of the muscle and myocardium.
Adrenergic nerves - emitting from their endings adrenaline or noradrenaline.
Autoregulation of blood vessels is their response to local mechanical and chemical effect without the participation of nerves.
Afferent - upward to the nerve centers.
Batmotropony - changing anxiety (myocardium).
The mesentery - fold peritoneum (contains blood vessels and nerves).
Brown fat - fat, rich in mitochondria. An important source of energy, especially in young animals.
Vasomotor - vasomotor.
Autonomic nervous system - nervous system that ensures stability of the internal environment of the body. Consists of afferent part (mainly interoception), vegetative centers of the brain and spinal cord and efferent departments (sympathetic and parasympathetic).
Vegetative - related functions that are common to animals and plants: Nutrition, digestion, metabolism, etc.
Ganglion nerve node.
Hyperemia - increased circulation.
The hypothalamus area of the brain under visual hillocks, which plays an important role in the activities of internal organs and its coordination with the work of the various systems of the body.
Humoral regulation (from lat. "humor" - liquid) - regulation with the help of substances transported by the blood.
Dromotroponuu - changes the speed of propagation of an excitation in the myocardium.
Capacitive vessels - thin veins, containing a large amount of blood and are in the thick fabrics.
Visual halls (visual hillocks, thalamic brain area, subcortical ganglia) - pair formation, perform complex functions; here are the pathways between the higher parts of the brain and the rest of the nervous system.
The impulses activity excitable tissues.
Inotropic - effect on the strength of heart contractions.
Ischemia - poor blood circulation.
Cutting - located closer to the tail.
CABG (coronary) vessels - vessels that feed the heart muscle.
Cranial - located closer to the head.
Latent (Latin. - latent) period - the time from the beginning of exposure to the response.
The mediator - chemical mediator, conveys the excitement of a neuron to a muscle, gland or another neuron.
Mitochondria - intracellular structures involved in the exchange of energy.
Oncotic pressure - osmotic pressure caused by colloidal particles.
Orthostatic position - vertical position of a body (standing), impeding the return of venous blood to the heart and blood supply of the brain.
Osmotic pressure is the pressure exerted dissolved in a liquid substances.
The parasympathetic nervous system - the Department of efferent part of the autonomic nervous system, the preganglionarnah neurons which lie in the brain stem or in the sacral region of the spinal cord, and postganglionarnyh neurons inside innervated authority or near it; the mediator is usually acetylcholine.
The pacemaker is a place of forming of rhythm.
Perfusion - natural or artificial leakage of blood or other fluid within the blood vessels of the body.
Plasma is the liquid part of blood.
The edge of the trunk (the sympathetic chain) - pair formation, inherent vertebrate and consisting of tel postganglionarnyh neurons (sympathetic). Is the switch of the excitation with the preganglionarnah neurons at postganglionarnye. Participates in reactions of the type of stress.
Pressorne reflex reflex, followed by high blood pressure.
The medulla is the lower part of the brain, bordering the spinal cord. It contains most of the pathways of the brain.
Resistive vessel - a vessel providing the resistance to blood flow, mainly of the arterioles.
Remission - improvement in chronic disease.
Sympathetic nervous system - the Department of efferent part of the autonomic nervous system, the preganglionarnah neurons which are located in the thoracic and lumbar regions of the spinal cord, and postganglionarnyh - in the sympathetic chain or separate ganglia. The mediators - the catecholamines, acetylcholine and other
Synapse - contact nerve fibres with a cell or its process which is used for one-way transmission of excitation.
The somatic nervous system - nervous system, which provides reduction of skeletal muscles.
Transmural pressure (in particular, transcapillary) - the difference between pressure in the hollow body and outside of it.
The chyme - digested the contents of the small intestine.
Cholinergic nerve - efferent nerve allocating their endings as a neurotransmitter acetylcholine.
Chronotropic - affecting the frequency of cardiac contractions.
The cytoplasm is the internal environment of the cell.
Exteroceptors - sensitive nerve endings, perceiving signals from the external environment.
The effector is an organ or cell, reacting to a stimulating effect.
Efferent - coming from the nerve center or the ganglion.
