Web71. A solid metallic sphere has a charge +3 Q. Concentric with this sphere is a conducting spherical shell having charge – Q. The radius of the sphere is a and that of the spherical shell is b ( b > a ). What is the electric field at a distance R ( a < R < b) from the centre. (1) Q 2πε0R. (2) 3Q 2πε0R. (3) 3Q 4πε0R2. WebThe transmission of impulses through the neuron is called propagation or conduction of nerve impulses. The impulse transmission is by electrical potential and wave like. The neurons are two types based on presence and absence of myelin sheath. They are myelinated and non-myelinated neurons.

How Is A Nerve Impulse Transmitted Across A Synapse?

WebNerve Impulse Transmission Within a Neuron. All functions performed by the nervous system—from a simple motor reflex to more advanced functions like making a memory … WebNerve Impulse is transmitted across the Synapse: There are two types of synapses i.e. chemical and electrical, depending upon the nature of the transfer of information across the synapse. Chemical Synapse: The axon terminal divides into many branches and each ends into a synaptic knob. dickinson maryland
