Sensory neurons carry signals from different parts of the body to the

Copy and identify the type of neuron given below :

From the diagram given below name the parts A and B. Also, write the function of Part A and Part B. 

(i) Name the parts labelled A and B in the neuron drawn above.

(ii) Which part acquires the information in the neuron?

(iii) Through which part does the information travel?

(iv) In what form does this information travel?

(v) Where is the impulse converted into a chemical signal for onward transmission?

Electrical impulses are an excellent means of quick transfer of information in animals but there are limitations to the use of electrical impulses. List such two limitations.

Define nerve impulse. Which structure in a neuron helps to conduct a nerve impulse
(i) towards the cell body           

(ii) away from the cell body
