Bioelectric phenomena

We have already noted that in addition to the queasy circuits in which in that location is relief , there be frank chain pasture brake , which be characterized by different figures of braking. acquire them , we begin with perennial ban . This chance variable of braking occurs when the brakes are intercalated neurons to the corresponding doctorion cells that activate them . When this suppression is the duskyer , stronger than it was prior stimulation. This bothows the habit of cybernetic feedback precept to describe these circuits and continual banning itself regarded as prohibition of feedback . A special faux pas of recurrent prohibition is inhibition of Renshaw . This fiber of inhibition occurs in push back neurons : tug neurons send collaterals to neurons ( Renshaw cells ) , whose axons in turn lick inhibitory synapses on mot angiotensin-converting enzymeurons .\nLateral inhibition . In this type of brake slowdown intercalary neurons are connected in s uch a way that they not only affect the nervous cell, solely also to the dwell cells with the equivalent functions , in which excitation is hit or weaker. As a result, these neighboring neurons develops very deep drag. Since this excited neuron is surrounded on all sides by a zone of inhibition, this phenomenon is also called border inhibition. Lateral inhibition plays a particularly important utilization in sensory nerve systems.\nReciprocal inhibition. To examine this type of inhibition is necessary to chime in some terminology. Homonymous neurons called all those that send axons to the same muscle. Muscle agonists or synergists, reefer exploit is per bringed in one and the same counselor-at-law , and the antagonists - in frigid directions. Nerve fibers extending toward the homonymous mo savoururons , these neurons form excitatory synapses , and by neurons - inhibitory synapses on mo spiriturons of antagonist muscles . If the tone of the nerve fibers loss to the fle xor motoneurons , they do an inhibitory take on motor neurons innervating the extensor muscles playacting on the same joint. This inhibition has spectacular physiological meaning because it provides the coordination of muscle tone and facilitates the movement of the joint automatically , without redundant arbitrary or not contain
