why are neurons called excitable calls ? Mention special featureas of the membrane of the neuron .

Explanation

Different types called excitable cells because these membranes are in a polarised state. Permeable types of ion channels are present in the neural memebrane i.e are selectively peremable to different ions .
When a neuron Is suitably stimulated an electric disturbance is generated , which swiftly travels along its plasma membrane .Arrival of the distubance at the neuron 's ending or output zone triggers events that may cause stimulation of differential concentration grasient of ions (specially natural `K^(+)` ) across the membrane .
the specila features of membrane of neuron are
(i) Excitility Neurrons are able to percieve stimulus and enter a state activity caused by change in electrical potential differnce across its covering membrane .
(ii) Consuctivity Change in potential difference spreads through the membrane to the whole neuron .
(iii) COnnectivity Neurons are conneceted to several others receing and connected to several others receving and transmitting impasse to several others , receving and transmtitting impulses to various directions
( Iv) Response the processed amssage amy elicit a resoponse in the form of a sensaton .
